Hi,
These are the few things you need to do to fix Windows Update Error 0x800f0801 in Windows 11 or Windows 10. It usually occurs with a Feature Update.
1.Use Windows Update Assistant
- Run Windows Update Troubleshooter
To do this, you can follow the given steps.
Launch Settings by Win + I.
Click Update & Security > Troubleshoot > Additional troubleshooter.
Select Windows Update and click Run the troubleshooter.
Wait for the process to complete and check if it fixes the issue.
- Repair .NET Framework

c:\windows\SoftwareDistribution c:\windows\SoftwareDistribution.OLD

Finally, restart your computer and check if it fixes the Windows Update error for you.
- Run DISM to repair Windows Update components.
To do this, launch Command Prompt as an administrator from the Start Menu and run the following commands.
DISM.exe /Online /Cleanup-image /Restorehealth
Check if it fixes the issue.
if your Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or
use a Windows side-by-side folder from a network share, as the source of the files.
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAcces
You need to wait for both of these commands to complete their task.
Once the process is complete, DISM will create a log file in %windir%/Logs/CBS/CBS.log and capture any issues that the tool finds or fixes.
Finally, check if the Windows Update error is fixed.
