I tried this earlier in the day but it still failed. The only option I can change is Virus and threat protection settings which I disabled. It might be a conflict with something I have installed but no idea what. I don't have much installed. A few games and such.
I looked at your posts and watched youtube. KB5014697 was successfully installed on mine.
So you had tried deleted Windows Update cache, disabled Windows Defender, ran Windows Update Troubleshooter, ran Windows Update Reset Tool did not help it.
I googled 0x800f0988 Windows 11 found some links that may help you to fix issue.
I looked at error code 0x800f0988.txt and compared to Windows Update Reset Tool batch file found some difference.
error code 0x800f0988.txt
Code:
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
Windows Update Reset Tool
Code:
del /s /q /f "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"
del /s /q /f "%ALLUSERSPROFILE%\Microsoft\Network\Downloader\qmgr*.dat"
Windows Update Reset Tool batch file to delete only one file gmgr*.dat but not all files!
Let try
error code 0x800f0988.txt as batch file to see if it will fix your issue.
If it still not worked then try DISM and SFC.
Code:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
DISM /Online /Cleanup-Image /RestoreHealth /Source:E\Sources\install.wim /LimitAccess
SFC /scannow
if all above still not help then do you have additional languages installed? Tried manually install KB5014697 from Microsoft Catalog?
Resolve the update failed with error code 0x800f0988 on your Windows 11 PC with these simple instructions.
