Windows 10 does not load when turned on. What to do if your computer stops working after an update. Wireless mouse does not work

Windows 10 updates are important because they keep the system up to date. If, after installing updates, the OS stops working and does not even start, you will have to take a number of steps to resolve the error. In this article, we have collected all the main reasons why the operating system does not start or immediately crashes, as well as the main options for solving this misunderstanding.

First, let's outline the 3 main problems that happen:

  • The operating system took a long time to load;
  • The system gets to the point of entering the password and then does not work;
  • A black or blue screen appears and the OS does not load at all;

There are also several reasons:

  • Problematic update;
  • Installation error;
  • Other reasons;

There is good news for you - any system, if it is a software problem, can be restored. As a last resort, Microsoft has provided a complete rollback or reinstallation. The most critical scenario is that you will lose some of your data, but together with you we will try to prevent this from happening and will further consider several main ways to restore normal operation without losing data.

The system starts slowly, but works

The easiest problem to solve. All you have to do is revert back to the previous version of the OS you had before you decided to upgrade. You won't need to download anything. It is enough to patiently wait for the download, no matter how long it may be (more than 40 minutes is unacceptable, which means the OS will not load). Next, go to system settings (open by right-clicking on “My Computer”) and select the item: system protection.

A new window will open where you will find the “Restore State from Checkpoint” option. Select it and click the “Next” button. You will see all available points with the date they were created. If the problem arose after starting the update through the official installation center, then today’s date will definitely be shown here. Before starting updates, Windows 10 always makes a point, just for such situations. Select any one, click “Next” and follow the instructions on the screen.

There is another way, but it is radical. If the OS works, you can always roll back to factory settings. To do this, in the control panel, find the “Update and Security” item, where go to the category: Restore the computer to its original state. Select this item and the OS will offer the following:

Please note that even the “Keep my files” option will cause you to lose some of your data. This especially applies to installed software. It will disappear, and you will need to download and other utilities again. Add our site to your bookmarks to quickly restore all the software you need.

Using bootable media

This option is already for those whose OS does not start, or only reaches the password window. If you have not created it, you will need to create it on another work computer. We connect it to your problematic PC and launch the operating system in safe mode. This can be done in 9 cases out of 10. And then you are required to check the performance of the computer, as well as look at critical and vulnerable spots:

  • Scan the system for viruses;
  • Check the startup area;
  • If possible, disable unnecessary software;

You can do the first thing using or any other free solution. The second you can do with or using another utility. We also recommend disabling various utilities that you even need and removing them from the startup area. This is required in order to eliminate the possibility of a software conflict.

After all these steps, try restarting the system in normal mode, without using a bootable USB flash drive. If the OS starts, then congratulations, the problem is solved. If the situation has not changed, then you will have to move on.

Recovery without a bootable USB flash drive

This option does not require external sources, but may result in the loss of some information. You need to restart your computer, and at the earliest stages of booting, press F8. This will take you to a special diagnostic and recovery menu. Do not confuse this window with BIOS/UEFI, which we wrote about earlier. In this window you need to do the following steps:

  • Go to the “Diagnostics” section;
  • Next “Advanced options”;
  • Open the “Recovery” tab;

This will take you to a panel that will take you to your recent restore points. Follow the instructions on the screen. After selecting a point (not necessarily the closest one), the PC will reboot and everything will be fine. But there are two nuances: there are not always points, and the method does not always help. But of all the less painful options available, this is the main one.

Windows 10 always creates a rollback point when updating, unless you manually change this and abandon this practice. There is also an alternative method. At the "Advanced Options" stage, you can use two other built-in tools:

  • "Return to previous build"
  • "Startup Repair"

They are shown in the screenshot below:

The first one will help you roll back just like in the method described very first. The second will allow you to automatically fix problems that prevent Windows from loading correctly. But neither one nor the other is reliable, since in most cases they either do not find the error, or find it and cannot fix it. Therefore, the rollback method is the best in this context.

Blue or black screen problems

This type of problem is one of the most critical; it is worse only if the PC does not start at all. In this case, you see either a black screen or a white screen with an error code. You need to remember/rewrite it and then find a solution specifically on this issue on the Internet. We will consider only the most (80% of cases) reason, which is associated with the code: CRITICAL_PROCESS_DIED.

In this case, when starting the PC, you need to press F6 (the key may differ depending on the manufacturer of the mother card, check on the manufacturer’s official website) and wait until it boots in safe mode with command line support. Next, if this mode is successfully launched, go to the command line and enter the commands:

  • sfc /scannow
  • dism /Online /Cleanup-Image /RestoreHealth
  • shutdown-r

Strictly in order as we have listed them. After each command, press Enter and wait for completion. The first two will take literally a moment, the third will turn off the device and you will need to start it yourself. Many people get scared, thinking that they have made the problem worse - but no. Start your computer (or laptop, the technology is the same) as usual, but do not press any keys or select special modes. In the end, everything should work.

All this will allow you to manually restore system files to their original state.

The black screen has two varieties - completely black, possibly with text, or black with a mouse cursor. How to solve the latter is described in detail in the video below:

If everything described did not help you, then use the OS recovery capabilities, even reinstalling from scratch. Finally, we note some additional causes of difficulties that can also be solved thanks to these instructions.

Good health, my dear readers, brothers in the computer field, as well as just guests of the site.

Yesterday I updated the operating system and could not boot from it. The fact is pedal, but quite solvable. After delving into the essence and causes of the problem, I found a way out. Therefore, today I will tell you what to do if Windows 10 does not boot after the update. Read carefully and remember!

Why could this happen?

There can be many factors, both consequences and causes. We caught a virus (in this case Comodo Internet Security will help), the update was crooked, the application store did not work, and much more. It is quite possible that the registry structure has simply become damaged, which is why Windows simply cannot find the boot sectors. Monitoring the stability of your personal computer and a couple of support programs will help prevent this situation.

For example, SS Cleaner. Ideal for users with minimal computer knowledge. Also, it’s quite suitable - Reg Organizer. Also excellent software that will help clean and configure the system.

It often happens that the update package comes out quite crude, therefore, due to a conflict with any of the drivers, the operating system may slow down, for example, the computer freezes on the screen saver. This is quite fixable, and we will look at examples of solving this problem below.

It is important to understand that any service packs and patches must be downloaded only from the Microsoft website. Otherwise, you can completely ruin the installed graphical shell with low-quality content, to which, quite possibly, an inexperienced programmer, or even a hacker, had a hand, which is even worse. Since this can harm the most important aspect - security.

What to do if the laptop freezes on the screen saver?

First of all, I would like to warn you right away. In Windows 10, the installation of updates is slow. If the initial operating system startup screen hangs for 2-3 minutes. This does not mean that the system is slow. Perhaps at this time, the process of setting up installed files and script databases is underway. It can even take up to 10 minutes, depending on the size of the update itself. Therefore it is better to wait. And if after this time the OS does not react in any way. Then you can work on solving this problem.

If the laptop freezes on the screen saver, we need to roll back to a stable version.

I want to immediately warn you that this method is not a panacea and it will not help fix all the problems with Windows at once. It only helps to fix the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet. There is no boot menu for the latest working configuration in the latest version of the operating system according to the standard, but this item can be added.

We go to start, and in the execute line we type the command regedit.

The registry will open, we need to move to the section HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Configuration Manager. Here I’ll draw your attention to a parameter called BackupCount. It is responsible for how many times the system will save its state for rollback. According to the standard, there is only one, but you can change this number yourself.

Now we go, as shown in the figure below, to the OS configuration manager. You need to create a subsection there. It should be called like this - LastKnownGood. In it you need to create a parameter called - DWORD, don't go wrong with the name. Set it to Enable.

This should also help if you are experiencing a blue screen after the update.

How to restore the system more correctly?

It happens that after installing the drivers, a black screen appears. A simple rollback will not help here, since the software part of the operating system is affected. a complete restoration is required. You can do this in 5 different ways.

First. We go to the start menu, there we go to our system settings and select “ System protection».

Now you need to choose restoring state from a checkpoint and press Further. A table with time parameters will appear in which you need to select the earliest point. Click it and restore it. In this case, we will not lose files and we will not have to go into the BIOS.

Second. A more radical method. It is based on resetting Windows to its original factory settings. This is like a reinstallation, however, you will not need to copy and then restore files. The OS will not erase them. We go to the settings of our laptop, then to the update and security section. Then click on the restore line and select - return the computer to its original state.

Third way, which uses file backup. Suitable when error 1607 appears. The latest version of the operating system has the ability to copy virtually all files for recovery. If necessary, they can be extracted and installed as the main version of the software, thereby solving problems with new versions. But in this case, you will need to enable a feature called file history. You will also need an external storage device – a flash drive or hard drive. Go to the settings of our computer and open the section recovery and security.

On the left side, select from the menu archiving service. Now on the right side you need to click on the plus sign and select external drive partition, to which the data will be saved after it has been copied.

If everything is completed and carried out correctly, a switch will appear. It should be blue, which means the function is enabled.

All now selected files, which can be configured manually, will be compressed and sent to the external device.

Fourth. Using a recovery disk. An extremely useful method, although it requires quite a lot of time. Helps with incorrect installation of video card drivers. It will also help if the mouse on your laptop does not work. So, we insert a clean flash drive into our USB port. Next, go to the start menu and there in the search bar we type the words - recovery disk. A section for creating one will appear.

The same can be done by pressing the key with the Windows icon and the K key (R in English).

A window will appear with a description of why such a feature is needed in principle. We need to click the checkmark at the bottom and click next.

I would like to immediately warn you that a flash drive needs at least 4 gigabytes. This is due to the fact that Windows 10 is quite large in itself and the hard drive with recovery data will be quite weighty. This will be written in the next window. If everything is in order, the operating system itself will find the media and delete all data from it.

The formatting of the flash drive will then begin. It will take no more than 5 minutes. Next will be copying the files. Here you have to wait from 10 to 30 minutes.

If everything is fine, then you will see a sign like this.

If you get a black screen or key f8 does not work does not work, then you can use this recovery disk. Just boot from it and select the very first icon on the top left.

Fifth. Using the installation disk. If you don't have one, I'll explain how to do it. We take a flash drive of 8 gigabytes or more. We copy all the necessary files and format it. Downloading the image operating system and check it for viruses using AVG AntiVirus Free.

A from here UltraISO program. Next, install it and open it. Next click here.

If Windows 10 does not boot, there may be different reasons. The main thing is to know exactly how to act in such a situation.

Main reasons

There are many reasons why the operating system does not start. The main factors are the following:

  1. Another operating system is installed on another drive. As a result, the boot loader of the old operating system will be replaced by a new one.
  2. Experimenting with disk partitions. For example, they can be divided again, combined, compressed, formatted, and other actions.
  3. Incorrect manual editing of the registry itself.
  4. Using various cleaning applications in Windows 10 to speed up the system and decorate it. As a result, such programs can accidentally change registry keys and various files that should not be touched at all. Because of this, Windows 10 will not start later.
  5. Incorrect update of the operating system or shutdown of the personal computer when the system was just being updated and started.
  6. Driver failures. Usually in such cases the screen is blue or black. Sometimes the name of the driver that caused the problem is written.
  7. Some programs that are on autorun. In this case, failures occur in the late stages, when the computer turns on, but before the desktop appears.
  8. If a black screen appears on Windows 10, then the cause may be viruses and anti-virus programs, which can cause no less harm than the viruses themselves.

If Windows 10 won't boot, there may also be hardware reasons. These include the following:

  1. The order in which bootable media is polled in the BIOS has been changed. For example, the whole process is slow due to the fact that the computer looks for the bootloader on the flash card, and not on the system disk.
  2. The drive is connected to a different port on the motherboard where it previously functioned. As a result, crashes and blue screens occur.
  3. Problems with RAM. Because of this, the personal computer starts the same process again after rebooting.
  4. Malfunction of video subsystem parts. In this case, the operating system will start, but the person will not see it, only a black screen. Sometimes you can tell when the system is loading only by characteristic sounds.
  5. Other equipment malfunctions. For example, this applies to the motherboard, power supply, and peripheral devices. In this case, the computer does not start the first time.

There are many other factors that must be taken into account.

Preparatory work

First of all, it is recommended to prepare for the worst in advance. In 90% of cases, Windows 10 does not start due to software problems. Then you can deal with the problems yourself. If Windows 10 won't start, everyone should know what to do.

In this case, the computer will boot into the recovery environment. If a person had previously used version 7 of this operating system, and did not have a ten, then the recovery environment was installed together with the main system on disk. To find it, you need to go to the additional boot methods menu. To do this, press the F8 key, then select the “Troubleshooting” category.

In version 10, the recovery environment is also included, but compared to version 7, the time to download it has become significantly shorter.

To have time to launch it, you must simultaneously press F8 and Shift. But this will only help if the fast boot function is disabled in the settings and the system was installed on an MBR hard drive. If the software was running on a GPT or SSD disk, then bootable media is required. For such emergencies, it is best to keep a flash card or disk nearby, and the system capacity should be the same as on a laptop or computer.

As for the recovery environment, in most problematic cases the operating system tries to repair itself - for the second, third and other times. If she succeeds, the user will not receive any error messages. In this case, the computer will simply take a long time to start. If the actions had no effect, a message or a black background with a blinking cursor appeared on the screen.

If a message appears on the screen, you need to select "Advanced options" to get to the recovery environment that is on your hard drive. In this case, you will not have to download it from another medium.

If the computer does not show any signs of life at all except for a black or blue screen (perhaps the appearance of a sad emoticon), then you need to have a distribution kit with the tenth version of the operating system.

The media must be connected to the computer and selected as the first device to boot.

As a result, windows start up. In the first one, which appeared immediately after turning on the disk or flash card, you will need to select the appropriate language and click “Next”. Then proceed to installation and restore the operating system. To do this, select the “System Restore” option. In the Select Actions dialog box, you need to click on the Troubleshooting option.

Startup recovery

  1. Recovery. In this case, run rstrui.exe - this is a standard utility that is intended to roll back the system to one of the save points.
  2. Image restoration. In this case, the Deployment Wizard will restore the operating system from the backup that was created earlier.
  3. Boot recovery. It will help you restore various partitions and files and correct their errors.
  4. Command line. Various utilities start working.
  5. Return to the previous build. In this case, a rollback to the previously used version is launched on Windows 10; it was updated to the tenth version.

If Windows does not start, you can begin boot repair. This option is effective if boot files have been damaged or deleted. In addition, this method is suitable if there was accidental formatting or actions were taken with the “System Reserved” category.

If the operating system does not load for a long time, you can rollback to a checkpoint that was created recently. This remedy is considered the best for various system failures. Moreover, this option will help even if the causes of such problems are still unknown. You need to click on the first item. As a result, the recovery utility will start. In it you need to select the time and date until which you want to rollback. Then follow the instructions that appear on the screen. But to use this option, you need to have at least 1 save checkpoint. In addition, the restore function should also work.

If the tenth version of Windows does not load for a long time, you can return to the previous build.

This recovery method can only be used for a short time after updating the seventh and eighth versions to the tenth - depending on the conditions in the license, this is from 10 days to a month. This option is only available if the previous version was saved in a separate file called Windows.old. In this case, personal files will remain the same, however, everything that was already there after the update will be cancelled.

Another option is to restore the system image. In this case, a backup copy is also used. It can be returned in case of any failures, but the problem is that rarely does anyone create such images. If it really was done before, then you need to select the item, indicate to the program the location where the image is stored, and then follow the instructions on the screen. This method is considered very effective, but is rarely used.

Conclusion

Many people are wondering what to do if the Windows 10 operating system does not load on a personal computer for a long time. In fact, this can happen at any time; the most important thing is to know exactly how to restore the system correctly.

Every second Tuesday, Microsoft releases a new batch of updates for its operating systems, which are installed on all computers through the Windows Update service (updates are obtained from Windows Update servers), internal WSUS, or manually using . In most cases, updates fix a specific vulnerability or problem (bug) in Windows or other products. However, in some cases, new updates may cause various problems in the system (due to incomplete testing, engineering errors, incompatibility with hardware, etc.), and the installed update must be removed. This is easy to do (see article). But what should you do if, after installing the update, the system does not boot, displaying a blue screen of death (BSOD)? In this article we will look at just such a case: how to remove problematic updates in Windows 10/8/7 if the system does not boot.

First of all, check whether the system boots in one of the safe modes (enough 3 times in a row interrupt the system boot with the power off button).

Advice. If your computer stops booting after updating the Windows 10 build with the “ ” error, you need to use the system recovery method from the link.

If Windows does not boot in safe mode after a bad update, you need to boot from any available disk or flash drive: this can be a Windows recovery environment (), Windows installation disk, ERD (aka) or another boot disk.

Note. Windows 10 and 8, if the system does not boot, the recovery environment with the command line should automatically load.

In our case, I will boot the computer from the Windows 10 x64 installation disk.

Advice. Any installation disk is suitable for downloading (the main condition is compliance with the OS bit depth), taking into account compatibility. Thus, the Windows 10 installation image can be used to restore Windows 7, but vice versa it will not work, because Older OS versions may not support all commands and options.

On the second screen prompting you to start installation, you need to click Repair Computer or press the keyboard shortcut Shift+F10.

In the first case, select Troubleshoot -> Command Prompt(Command line).

In the command prompt window that opens, you need to determine the drive letter that is assigned to your Windows system partition (this may not be the C:\ drive).

Issue the command: DISKPART

List the partitions in the system: list volume

End the diskpart session with the command: exit

In our example, you can see that the system drive is assigned a letter D:\.

Let's display a list of packages installed on the system located on the specified disk:

If you know which specific update (KB) caused the problem, its number can be used as a filter:

DISM /Image:D:\ /Get-Packages /format:table | find "4056887"

Or you can filter the list by installation date:

DISM /Image:D:\ /Get-Packages /format:table | find “01/18/2018”

Note. If the list of updates is very large, and you don’t know exactly which of the latest updates caused the BSOD, the full list can be downloaded to a text file and opened using Notepad (you can use the search in it).

DISM /Image:D:\ /Get-Packages /format:table > d:\updates.txt
Notepad d:\updates.txt


Now you need to copy the identifier of the problematic package to the clipboard (select the package name in the command line and press Enter to paste the text - just right-click).

You can use the following command to remove the update:

DISM /Image:D:\ /Remove-Package /PackageName:Package_for_KB4056887~31bf3856ad364e35~amd64~~10.0.1.0

If you don't know exactly which specific update caused the problem, remove all recently installed packages one by one (rebooting and checking the system).

After removing the “update” bug, try booting Windows in normal mode. The system should boot normally

If you have an MSDaRT recovery disk, uninstalling updates is even easier. Just boot from the MSDaRT disk (the bit size must be the same), select Diagnostics -> Microsoft Diagnostics and Recovery Toolset. In the list of utilities you need to select Hotfix Uninstall(Remove patches).

Just highlight which updates you need to remove and click Further.

Many users experience some malfunctions and malfunctions in their computer device after updating Windows 10. The main ones are the following:

  1. Windows 10 does not boot for a long time.
  2. The system does not want to start and work.
  3. Black screen.
  4. A blue screen with errors appears.

To eliminate them, you need to understand the sources of operational failures and possible ways to get rid of these sources.

If the system does not start after the latest Windows 10 update, remember how it behaved before shutting down or rebooting. Perhaps some program was downloaded, or the error appeared after connecting a new device and virus software. In the course of troubleshooting such problems, the system may improve or deteriorate its performance. Therefore, it is necessary to be prepared to restore it and return it to its original, working condition.

The system does not start or takes a very long time to load

The system takes a long time to load or does not load at all - this problem occurs when a large number of additional programs are launched or malicious software is connected to the process. Therefore, you immediately need to check your computer for viruses and prepare an electronic medium with Windows 10 installation files.

To solve the problem, take the following steps:

  1. Using the media, we boot the device in safe mode. In the menu, select the source from which the system modules and drivers needed for your computer will be loaded.
  2. Open Task Manager. This can be done using the Ctrl + Shift + Esc keys. Find the Startup tab.
  3. Startup contains the entire list of applications that can be loaded when the system starts. It is necessary to select from among them the minimum that is needed for normal operation of the computer, and disable the rest.

These simple steps will help reduce system boot time and improve system startup.

Working with safe mode is useful when removing viruses, unnecessary programs, fixing driver errors, and activating an administrator account.


In addition, you can optimize and defragment the disk:

  1. Click on Start.
  2. Select the Computer tab, drive C.
  3. In the window that opens, find the Properties item and click the Optimize button.

Using the CCleaner program, you can remove all junk files from the disk and erroneous keys from the registry.

If Windows 10 does not work after updating, restore the system to an earlier working state. This method is only suitable if the computer creates system rollback points or restore points. To do this, you need to carry out the following procedure:

  1. Reboot your system. Once it turns on, press F8.
  2. The recovery menu appears.
  3. Go to Diagnostics, then Advanced Settings.
  4. Find the Recovery tab.
  5. Following the instructions, select a Restore point to a rollback state from the available list.
  6. Restart your computer. The current version of the operating system is removed.

Blue screen appears

CRITICAL_PROCESS_DIED. The error code is accompanied by the warning “The computer did not start correctly” or “Windows did not boot correctly.”

In such cases, a regular reboot helps.

INACCESSIBLE_BOOT_DEVICE. The error may appear after updating to Windows 10 or the motherboard BIOS, when restarting the computer after a system rollback, partitioning the hard drive, or when files are damaged.

The easiest way to resolve this error is:

  1. In the Automatic Repair window, select Advanced options.
  2. Among the list of parameters, you need to find Boot options - Restart.
  3. After the system restarts, press the F6 button to reboot into Safe Mode using the Command Prompt.
  4. Enter the command phrases one by one:
    • sfc /scannow;
    • dism /Online /Cleanup-Image /RestoreHealth;
    • shutdown-r.

System files will be scanned and restored if they were damaged.

Black screen appears

There are malfunctions in which the computer device does not turn on, and the screen is black after the update. This problem occurs when video card drivers are installed incorrectly, exiting sleep mode, removing a virus, or downloading updates.

The screen can have 2 types:

  1. With a mouse cursor.
  2. No cursor, solid black display.

In the first case, the screen can have not only a mouse cursor, but also a rotating wheel. What does this mean and what to do in such cases?

Software glitch

This happens when the system booted only for the first time before Windows 10, when you turned off and immediately turned on or rebooted the computer. A software glitch occurs as a result of an update.

To restore the system, you need to update it again.

System conflict with primary drivers

Previously installed drivers may create a conflict with the system, so to resolve this issue, do the following:

  1. Find Start - Control Panel. Under Power Options, click System Settings.
  2. Under Shutdown Options, uncheck the Enable fast startup (recommended) box.
  3. Save your settings.
  4. Click on Start. Find the Computer tab.
  5. Right-click Properties and do the following: Hardware - Device Manager - Video Adapters.
  6. Find your video card and Update drivers. Drivers are installed either automatically from the Internet or from special software.

In the second case, when the screen is only black without a cursor, start the system in safe mode:

  1. Hold down the Shift key on your keyboard and continuously click on the F8 button to open Safe Mode. This system launch is simple, but does not always work.
  2. In the window that opens, find the following sections: Diagnostics - Additional parameters - Command line.
  3. Type bcdedit /set (globalsettings) advancedoptions true.
  4. Click the Enter button.
  5. In the newly opened window, click Continue. The download continues.
  6. In the new window, select Enable Safe Mode.
  7. Press Enter.


Correcting virus activity

If the computer does not boot, the screen is solid and black, then most likely the system has been damaged by malicious virus software. Try to use the simplest method.

Boot Windows 10 in safe mode, scan with an antivirus application and delete infected files.

If viruses have damaged the explorer.exe file, which is responsible for the operation of the graphical interface, you can perform the following operation:

  1. Press Ctrl+Alt+Del keys simultaneously or open the Start menu.
  2. Go to Task Manager, then Run new task.
  3. Write explorer.exe in the line and run the task.
  4. Through the Run line, pressing the Win + R buttons, enter the regedit command.
  5. Expand the HKLM branch.
  6. Go to the Software section.
  7. Next, click the Microsoft - Windows NT - Current Version tabs individually.
  8. Open the Winlogon folder, then Shell and double click.
  9. Change the value to explorer.exe.
  10. Save your settings.

Getting rid of system malfunctions after upgrading to Windows 10 is not particularly difficult and does not require technical knowledge and skills from the user. After completing one of the operational procedures, the system will boot without delays or failures. Your computer will work better.
