Could not start Diagnostic Policy Service

There are cases when you want to undo some changes you’ve made to your computer and to do that you have to perform the System Restore task. However, if you encounter an error that states “To use System Restore you must specify which Windows installation to restore”, when doing so, read on as this post will help you fix the problem. This kind of error in System Restore could be due to corrupted files in the system. There are also situations where you are not able to boot up once you encounter this error which could be a big problem. On the other hand, this error might have something to do with corrupted BCD files. Whatever the cause is, here are some potential fixes you have to try.

Option 1 – Try to run System File Checker offline

Like pointed out, since the error might be due to corrupted system files, you can try to run System File Checker offline. How? Refer to these steps:

• You need to go to the Advanced Startup Options and from there select Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• After opening Command Prompt, type the commands given below and tap Enter right after you type each one of them.
  • Cd /
  • Dir

• If you can see the “Users” folder, that is your system’s drive. However, if you can’t see it, you can just change the drive-by assigning “D” as its alphabet volume.
• Then execute this command where “C” is the system drive: sfc /scannow /offbootdir=C: /offwindir=C:Windows
• Now repeat the given steps sequentially.

Option 2 – Try to run DISM tool

You can also run the DISM tool to repair the potentially corrupted system image. First, you have to check the health of the system like checking the integrity of the system files and Windows services. To run DISM, follow the given steps below sequentially.

• Open Command Prompt from the Advanced Startup options.
• After that, execute this command where “C:” is the system volume: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:C:WindowsWinSxS
• If you encounter an error after executing the given command, insert the Windows USB or DVD and then execute this next command where “E:” is the USB or DVD drive: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:esd:E:SourcesInstall.esd:1 /limitaccess
• In some cases, “install.esd” would be “install.wim” and in such case, you have to modify and execute this command: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:wim:E:SourcesInstall.wim /limitaccess

Option 3 – Try to repair corrupted BCD

As mentioned, the error could also be due to corruption in BCD, and to fix it, you can use Bootrec.exe – a built-in command-line tool used to troubleshot issues related to boot up and Windows Startup. Before you run this tool, make sure that you have inserted a bootable USB or DVD into your computer. Once you have that covered, follow these steps:

• You need to go to the Advanced Startup Options.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• Once Command Prompt has been pulled up, enter each one of the following commands and in the sequence that they are given to rebuild BCD files and repair MBR files:
  • Bootrec /Fixmbr
  • Bootrec /FixBoot
• After you execute the commands given above, you should see a confirmation message that says, “The operation completed successfully”.
• Now type the “Bootrec /RebuildBCD” command to rebuild BCD.
• Finally, close Command Prompt and then restart your computer to successfully apply the changes made.

Option 4 – Try to run the Automatic Repair Utility

You might also want to use Automatic Repair in fixing the error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 5 – Try to use the Windows Recovery Environment

If the four options given above didn’t help fix the problem, you could try running Windows Repair and a Windows bootable USB or DVD.

• First, insert the bootable USB or DVD and boot into it, and select the “Repair your computer” option.
• Next, once you see the manufacturer logo on your computer, tap the key to enter into Windows Recovery Environment.
• After that, change the Boot sequence to DVD drive under the UEFI Firmware settings and restart your computer.
• Once your computer has restarted, select the boot order and make changes accordingly as displayed in the BIOS.

Option 6 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “exe /OFFLINE:C:Windows” and hit Enter to execute the command which will start the System Restore process.

Note: You need to replace “C” with the drive where Windows Installation is located.

In case you don’t know, Windows 10 actually allows users to set the Keyboard Repeat Rate and Repeat Delay. Both of these terms are interrelated and when you make active, any text field or an editor and then press and hold a single character key, it will quickly type the character for the first time and will show delay until the second and later characters appear. This is what you call the Keyboard Repeat Delay. On the other hand, the rate at which the later character appears is known as Keyboard Repeat Rate. There are two ways you can set the Keyboard Repeat Rate and the Keyboard Repeat Delay on Windows 10. The first one is using the Keyboard Properties while the second one is using the Registry Editor.

Option 1 – Set up Keyboard Repeat Rate and Repeat Delay via Keyboard Properties

• First, tap the Win + R keys to open the Run dialog box and type in “control keyboard” in the field, and hit Enter to open the Keyboard Properties.
• From there, you can use the slider to make the respective options for both Keyboard Repeat Delay and Repeat Rate shorter or whatever you prefer them to be.
• You should also see a text field in the mini window where you can test out your preferences. Once done, click on the Apply and OK buttons to save the changes made.

Option 2 – Keyboard Repeat Rate and Repeat Delay via Registry Editor

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERControl PanelAccessibilityKeyboard Response
• From there, you can set your own value for both the AutoRepeatDelay and AutoRepeatRate registry keys so that you can set the Keyboard Repeat Rate and Repeat Delay in Windows 10.
• Once you’re done, exit the Registry Editor and restart your computer to save the changes made.

As of late, users have been reporting about getting an error saying, SAFE_OS phase error during Replicate_OC operation when they tried to upgrade their Windows 7 or Windows 8.1 computers to Windows 10. Although the error code in this problem could vary, in this situation, it states:

0xC1900101 – 0x20017, The installation failed in the SAFE_OS phase error during Replicate_OC operation

To fix this issue, you need to follow the given options below. But before you do, you need to create a System Restore point first so that if anything goes wrong, you can always undo the changes you’ve made.

Option 1 – Try to change the Windows 10 installation

According to security experts, one of the main causes of this error is the KB3064209Windows Update. This particular update is the one responsible for updating the CPU Microcode for processors made by Intel. Thus, if you don’t use an Intel processor, you can skip this option and proceed to the next one. However, if you use Intel, make sure to follow the instructions in this option carefully. Take note that in this solution, C: partition is referred to as the OS Partition while H: partition is referred to as the USB Pen Drive.

• First, you need to download the Windows 10 ISO from the Windows 10 Media Creation tool and then copy its contents to the Pen Drive H.
• Next, tap the Win + X keys and click on the Command Prompt (Admin0 option. If a User Account Control appears, simply click Yes.
• After opening Command Prompt, type the following command:

dism /Mount-Image /ImageFile:H:sourcesboot.wim /index:1 /MountDir:C:UsersUserDesktopmount

• Now navigate to the following path in the Windows File Explorer:

C:UsersUserDesktopmountWindowsSystem32mcupdate_GenuineIntel.dll

• From there, right-click on the file named “mcupdate_GenuineIntel.dll and click on Properties.
• Next, go to the Security tab and click on Advanced. In the Advanced section, change the Owner to your User Account and click OK.
• And then back to the Security tab, click on the Edit button and check on Full control to make sure that your User Account has all the privileges.
• Now click on Apply and then OK.
• After that, delete the file you saw earlier which is named mcupdate_Genuine.dll.
• Then close all the Windows File Explorer instances and go back to the Command Prompt window and unmounts the image you mounted before by typing the following command:

dism /Unmount-Image /MountDir:C:UsersUserDesktopmount /commit

• Afterward, repeat the steps from mounting up until here for these files:
  • wim /index:2
  • wim /index:1
  • wim /index:2
• Now delete the mount folder and remove the USB Pen Drive and then boot with the installer.

Option 2 – Try to perform a Disk Cleanup

Chances are, some unnecessary files in your computer might be interrupting the installation process which explains why you’re getting SAFE_OS phase error during Replicate_OC operation instead so you need to perform a Disk Cleanup in order to fix the problem.

Option 3 – Try updating all your drivers

Every now and then, drivers get corrupted or outdated so it’s no surprise that they conflict with the operating system and cause errors like the SAFE_OS phase error during the Replicate_OC operation. To fix the problem, you need to update all your drivers. Follow the steps below to update your drivers.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it.

Option 4 – Try to update your system’s BIOS

Aside from outdated drivers, outdated BIOS could also be the reason why you’re getting the SAFE_OS phase error during Replicate_OC operation which is why you need to update your system’s BIOS in order to resolve the issue.

Option 5 – Try checking the Windows Services status

• In the Cortana search box, search for “Services” and then click on the Services icon.
• After that, the Services utility will be opened in a new window.
• Next, look for the following services:
  • BITS (Background Intelligent Transfer Service)
  • Windows Update Service
  • Cryptographic Service
• Then right-click on each one of the services and click on Properties. From there, select Automatic from the drop-down of the Startup Type menu.
• Now click on OK for each one of them and restart your PC to apply the changes made.

Option 6 – Try to check the RAM modules

There are many times when all the components of the RAM weren’t able to be used by the computer so you need to check the RAM modules.

• You need to first turn off your PC and then take out your RAM physically.
• Next, clean it with a soft cloth and blow some air into the RAM slot in the motherboard.
• After that, put your RAM back in the same slot.
• Then try updating your computer system again.

If you were trying to install a program on your Windows 10 computer but encounter an error instead that says, “Error 1310, Error writing to file: <PATH>, Verify that you have access to that directory” then read on as this post will guide you on how you can fix it. This kind is a fairly common type of error encountered by many Windows users. You can get this error when you try to install certain programs like Excel, AutoCAD, Adobe Photoshop, and some other Adobe products on Windows. One of the most likely causes for this error is that the required files or location is already used by some other software which means that Windows finds that you are trying to overwrite a software that is already installed. Aside from that, it could also occur if the program installer does not have access to write to that directory. To fix Error 1310, here are some potential fixes that could help.

Option 1 – Clear up temporary or junk files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.

Option 2 – Reinstall the program in a Clean Boot State

You can also troubleshoot Error 1310 in a Clean Boot state. It could be that there are some third-party applications in your computer that's preventing the program from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the program again.

Option 3 – Try to unregister and re-register the Windows Installer Module

• Tap the Win + R keys to open the Run dialog box.
• Then type the “msiexec /unregister” command and hit Enter to unregister the Windows Installer Module.
• Next, type the “msiexec /regserver” command and hit Enter to re-register the Windows Installer Module.
• Now restart your computer and see if un-registering and re-registering the Windows Installer Module fixed the problem or not.

Option 4 – Take ownership of the location where you want to install the app

The next thing you can try to do is to take ownership of the particular folder as this worked for some users who experienced the same problem. But before you do that, you have to create a System Restore Point first, once that’s done, proceed to the given steps below.

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.
• Finally, try to install the application again.

Hello and welcome everyone. In today's article, you will learn how to lock folder and content in it. Please be aware of few things:

1. The method is shown here works, but you need to be careful and follow step by step or you will damage your files permanently,
2. If you forget your password, you can not access your files anymore
3. Your files altho protected can still show up in recent files of some applications

All of that being said, let us start with locking the local folder on the computer with the password. Go to the folder where you have files that you would like to hide and lock with a password. Enter the folder and create the new text file inside it. Skip the name for now and go inside it. Copy and paste the following code inside the file:

---

cls @ECHO OFF title Folder Locker if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK if NOT EXIST Locker goto MDLOCKER :CONFIRM echo Are you sure u want to Lock the folder(Y/N) set/p "cho=>" if %cho%==Y goto LOCK if %cho%==y goto LOCK if %cho%==n goto END if %cho%==N goto END echo Invalid choice. goto CONFIRM :LOCK ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" echo Folder locked goto End :UNLOCK echo Enter password to Unlock folder set/p "pass=>" if NOT %pass%==Your-Password-Here goto FAIL attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker echo Folder Unlocked successfully goto End :FAIL echo Invalid password goto end :MDLOCKER md Locker echo Locker created successfully goto End :End

---

Now locate this line of code in the document: if NOT %pass%==Your-Password-Here goto FAIL and replace Your-Password-Here with your password. !!! Write down somewhere your password, if you lose it you will lock the folder even for you !!! Save the file as FolderLocker.bat and double-click on it to execute it. If everything was done correctly, a new folder with the name: Locker Move files that you want to hide and protect inside that folder. Double click again on FolderLocker.bat The command prompt will appear with the question do you want to lock the folder, press Y, and press ENTER. The command prompt will close and the Locker folder will disappear. In order to unhide and access the folder, you will need to double click on FolderLocker.bat again but this time command prompt with ENTER your password will appear. Type in your chosen password and the folder is back. If you wish to hide and lock it again just double click on FolderLocker.bat again, confirm with Y and it is hidden again.

Program and features are Control panel section where once accessed contains all programs installed on the operating system. From these windows, any logged-in user can modify applications, uninstall them, etc. If for whatever reason you want to limit this access to users and remove this group from the control panel please do keep reading as we show you how you can achieve this desired result using two methods: via policy editor or registry editor. Feel free to use any provided method as both works (except on Windows 10 Home edition) and achieve the same thing, it all comes down to preferred preference on how you wish to do things.

Local group policy editor method

This method is more straightforward and easier perhaps than its counterpart but it has one significant drawback, it will not work on Windows 10 Home edition which does not have in itself a policy editor included. If you are using Windows 10 Home edition then feel free to skip this method and do it via registry editor. That being said let's start:

• Press ⊞ WINDOWS + R to open the run dialog
• Inside run dialog type in gpedit.msc followed by ENTER to open Group policy editor
• Go to User Configuration\ Administrative Templates\ Control Panel\ Programs\
• Double-click on the setting named Hide Programs and Features page
• Change the toggle option from Not Configured to Enabled
• Click on the Apply button and then the Ok button to save the changes
• at this point, everything is supposed to be applied and your changes should take effect immediately. However, it has come to our attention that sometimes this is not the case. If you are one of these users which for whatever reason have not experienced applying to set momentarily do not despair and follow this quick guide on how to refresh settings and apply them right away.
• Press ⊞ WINDOWS + X to open the hidden menu
• Click on command prompt (admin)
• In command prompt type in gpupdate /force and press ENTER in order to force update and set setting right away

Registry editor method

The registry editor method is a more complex one but it will be your only way of doing it if as mentioned you are running Windows 10 Home edition. As always it is highly recommended to make a backup of the Windows registry before tempering with it.

• Press ⊞ WINDOWS + R to open the run dialog
• Inside run dialog type in regedit and press ENTER to open the registry editor
• If you would like to make a backup of the Windows registry go to File > Export and save the backup on a secure location naming it as you wish
• Locate the following key inside the registry editor HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Programs
• Right-click on the right pane of the Programs key and choose the New > DWORD (32-bit) Value option
• Name the value as NoProgramsAndFeatures
• Double-click on the NoProgramsAndFeatures value to open it
• Change the value data to 1
• Save the changes
• Reboot the computer in order for changes to take effect.

note: you can always change values back in order to show again panel by changing the value to 0 in registry editor or choosing Not Configured or Disabled in the local group policy editor

The Winload.efi file is an Extensible Firmware Interface or EFI file. EFI files are executable files for the firmware of the computers that are mainly based on UEFI and execute the tasks of loading the files to the bootloader of the computer. They are used for a specific set of tasks such as turning on the computer, installing Windows, restarting the computer or resetting it, and so on. This is why the Winload.efi file is a significant file so if it gets corrupted, lost, or damaged, it would be impossible for the Windows operating system to proceed. Here are some errors you can encounter that are related to the Winload.efi file:

• efi is missing
• efi cannot be found
• efi is missing or contains errors
• This program can’t start because winload.efi is missing from your computer
• This application requires the file winload.efi, which was not found on this system.
• There was a problem starting [path]winload.efi. The specified module could not be found.

In addition, the 0xc0000225 , 0xc00000e and 0xc0000001error codes are also associated with the Winload.efi file. Before you start troubleshooting the problem, you can try to perform System Restore first. This will help undo any changes you’ve made in your computer that might have triggered the Blue Screen error. To perform System Restore, here’s what you have to do:

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

If System Restore didn’t help in fixing the Blue Screen error, now’s the time for you to resort to the troubleshooting tips provided below but before you get started, make sure that your create a System Restore point first.

Option 1 – Try rebuilding the Boot Configuration Data (BCD) and repairing MBR

• Once you get to the Welcome Screen part, click on Next.
• Afterwards, click on the Repair your computer option located on the bottom-left part of the window.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• Once Command Prompt has been pulled up, the following commands to rebuild BCD files and repair MBR. Don’t forget to hit Enter right after you type each command.
  • bootrec /repairbcd
  • bootrec /osscan
  • bootrec /repairmbr
• Once the command line is successful in finding out a Windows installation, hit Y to let it boot from the list which will successfully rebuild BCD.
• Now type “exit” to close Command Prompt and then restart your computer to successfully apply the changes made.

Option 2 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve errors related to the Winload.efi file. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 3 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the error. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them

• Reboot your computer.

Option 4 – Disable the Early Launch Anti-Malware Protection

• You need to restart your computer in the Start Menu first while holding down the Shift key on your keyboard.
• After that, it will restart your computer to Startup Settings.
• Now ensure that the 8^th option is labeled as “Disable early launch anti-malware protection.
• Then tap the F8 key since the aforementioned option above is listed at number 8. This should launch and load Windows on your PC with the Early Anti-malware protection disabled for that session only when you try to carry out the same task and then check if the error related to the Winload.efi file is now fixed.

Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”

This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.

Option 1 – Uninstall programs you installed lately

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Perform System Restore

Performing System Restore can also help you fix the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run the System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why you’re getting the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Rebuild the BCD and fix MBR

Rebuilding the BCD can help you in fixing the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• Next, select Command Prompt and type in the commands below one by one, and tap Enter right after you do so.
• exe /FixMbr
• exe /FixBoot
  • exe /RebuildBcd

The commands you entered should rebuild the BCD and repair MBR.

Option 5 – Run the CHKDSK utility

You can also run the Chkdsk utility to resolve the problem. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in.

Manually cleaning your PC registry may be the worst or best thing you ever decide to do. Registry keys that lie around on your computer, unused, can cause your computer to lag. This can end up in your computer not being able to load the easiest of programs and being slow at loading anything, let alone something that would take up a decent amount of memory. If your computer has slowed to almost an absolute stop, it is most probably the registry’s fault and the only option then is to clean it. You can get programs to do this for you, but they can be riddled with inaccuracies and viruses that could harm your computer even more. This is why some people choose to manually edit their computer. However, this is not without its flaws.

Registry Keys

Registry keys tend to have really long names. These names will be full of numbers and hyphens and will most likely give you no indication of what they do. Even some computer experts find it hard to understand what every computer’s registry keys do. This can make it very hard to see which ones are causing the problem; and if you don’t know what’s causing the problem, then there is no way you will be able to fix it. Some registry keys will be completely menial in what they do but some could be vital to even allow Windows to work on your computer.

Manual Registry Repair

Registry keys can also cause huge problems if you manually delete the wrong one. A lot of registry cleaners have the option to revive a key that they have deleted on you, which means that fixing an error that they made would be easy enough to do. However, when you manually delete registry keys, it will be an awful lot harder to get them back to work again afterward. This can cause your computer many problems and if you delete even one wrong key it is possible your computer will not even start. With the horrid naming system they have as well, it makes it very hard to determine what is important and what is not, which means it is all too likely that you will delete something important. However, those are the risks you have to take when you are cleaning out your registry. A registry cleaner has the same likelihood of messing with your computer and deleting something wrong that you have, so it is the same either way however a registry cleaner will do it with less hassle. But, some people say that if you do it yourself, it’s more likely to be right; that is why they prefer to do it manually and that is alright.

Conclusion

So, if you are manually deleting your registry keys that are unused, you’ll have to use a program that comes with Windows known as ‘regedit.exe’ which is incredibly difficult to use but may just be worth the hassle in the end. So, you don’t really need to put up with a slow computer, but be careful when messing with your registry manually!

If you encounter a Blue Screen error that points to the Wdf01000.sys file, then this post might be of help. Wdf01000.sys is a file related to the Windows Driver Framework which is the one that manages the system drivers. So if this file ends up being corrupted, the drivers would start to cause trouble in the system which would lead to a Blue Screen of Death error eventually. There are lots of error descriptions that are associated with the Wdf01000.sys file such as:

• DRIVER_IRQL_NOT_LESS_OR_EQUAL

• Open Command Prompt as administrator and execute this command – verifier /querysettings
• The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
