Hello
Thank you for posting in Microsoft Community forum.
The errors you’re seeing, 0x800f081f for both DISM and SFC, typically indicate that the source files could not be found. This can happen when the utility is unable to access the necessary files to repair the system image.
Here are some steps you can try:
Check the System File Checker (SFC) log: The SFC tool should generate a CBS.log file that provides more details about the errors. You can find this file in the C:\Windows\Logs\CBS directory.
Specify a source file: If DISM can’t find the source files, you can specify a source file using the /Source flag. For example, if you have a known good copy of the Windows image that you’re trying to repair, you can specify it like this: DISM /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess.
Use Windows Update as a repair source: If you don’t have a separate repair source, you can use Windows Update by running the following command: DISM /Online /Cleanup-Image /RestoreHealth.
Perform a Windows repair install: If the above steps don’t work, you might need to perform a repair install of Windows. This should fix any system file issues without affecting your personal files.
Remember to run these commands in an elevated command prompt (run as administrator).
