Windows 11 Pro, WU 0x800f0983, sfc errors

[R4to0]

Hello,

First of all: thank you all the staff for making a free service for helping people with Windows issues with such high quality that even paid ones can't provide!


Now for the issue, I've been trying to fix this this entire week. Windows Update is unable to install updates, giving error code 0x800f0983. SFC report that there are files to fix but it couldn't, and log files mention a few files related to Hyper-V component. I've tried to uninstall (to then install again, I need it for WSL2) this component but it failed with code 0x80073701.

SFC output reports:

sfc /scannow

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files but was unable to fix some of them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.

Logs are attached.

DISM output reports:

Dism /Online /Cleanup-Image /RestoreHealth

Deployment Image Servicing and Management tool
Version: 10.0.26100.1150

Image Version: 10.0.26100.3476

[==========                 17.4%                          ]
Error: 2

The system cannot find the file specified.

The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

Also, attached.

ComponentScanner report attached as well.

Additionally, I ran dism /online /Cleanup-Image /StartComponentCleanup /ResetBase and it succeed although it didn't help in fixing both my issues above.

And last, in a bit of desperare I ran SFCFix with no parameter or scripts, and it crashed while scanning CBS log. I've allowed the app to submit a crash report, hope that's useful for the application too!

Hi and welcome to Sysnative,

Upload your COMPONENTS hive.

• Navigate to C:\Windows\System32\Config and locate the COMPONENTS file.
• Please copy this file to your desktop.
• Note: If you receive an error that this file is in-use, simply reboot your computer and try again.
• Right-click on this file on your desktop and select Send To > Compressed (zipped) folder. This will create a file named COMPONENTS.ZIP on your desktop.
• If the file is too large to upload here, upload the file to www.wetransfer.com and post the link in your next reply.

 

[R4to0]

Attached COMPONENTS file.

I ran dism /online /Cleanup-Image /StartComponentCleanup /ResetBase

After running this command some things hs been changed, so please run the following command again and provide the new CBS logs.

DISM /online /cleanup-image /RestoreHealth

 

[R4to0]

After running this command some things hs been changed, so please run the following command again and provide the new CBS logs.

Oh, sorry about that. Have ran only DISM /online /cleanup-image /RestoreHealth command again and here's fresh DISM logs, attached below.

 

[Maxstar]

Here's the first fix.

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFixScript.txt and save it to your desktop.
• Drag the SFCFixScript.txt file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

 

[R4to0]

DISM still failing, attached SCFix and CBS logs.

 

[Maxstar]

Additionally, I ran dism /online /Cleanup-Image /StartComponentCleanup /ResetBase and it succeed although it didn't help in fixing both my issues above.

Hi,

Did you make backups before running DISM with the /ResetBase parameter?

 

[R4to0]

Hi,

Did you make backups before running DISM with the /ResetBase parameter?

No, I didn't... Did I something bad with that?

 

[Maxstar]

Normally, DISM with the /ResetBase parameter will merge some subkeys in the COMPONENTS hive, but in this case it failed with an empty key. So please do he following first.

Step 1. Replace Components Hive Manually

Warning: this fix is specific to the user in this thread. No one else should follow these instructions as it may cause more harm than good. If you are after assistance, please start a thread of your own.

1. Download COMPONENTS.ZIP and save to your desktop.
2. Right-click on it and select Extract all.... Make sure the "Show extracted files when complete" is checked and click Extract.
3. Now we have the COMPONENTS file that we will be using to replace your current one.
4. Navigate to C:\Windows\System32\config
5. Right-click on the current COMPONENTS file and select rename. Rename it to COMPONENTS.bad.
   Note: If you get an error that the file is in use, reboot your computer and then try again.
6. Take the file from the Components folder on your desktop and paste it into C:\Windows\System32\config

Step 2. Reboot the system and run

ComponentsScanner again.

• Right-click ComponentsScanner.exe and select "Run as administrator", click Yes on the UAC (User Account Control) prompt which appears.
• Follow the on-screen instructions.
• Once complete, a report will be saved to your desktop called ComponentsScanner.txt.
• Post the logfile ComponentsScanner.txt as attachment into your next reply.

 

[R4to0]

File replaced, ComponentScanner result attached below.

[R4to0]

Ran SCFix, it applied some registry keys, then ran dism and it did completed with "The restore operation completed successfully." message after a few hours (that one took a long time to complete!). I've ran dism again for a second time to ensure there's nothing corrupted left to fix but it failed again.
