Hi gurus,

I am trying to uninstall Hyper V using Optionalfeatures.exe (in Admin mode) but failed with an error code 0x800f0831.

When chasing the error, I tried manual removal

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Having strong doubts about a corrupted Windows package, I came across couple of logs when unsuccessfully run

Dism /Online /Cleanup-Image /RestoreHealth

Dism.exe /online /Cleanup-Image /StartComponentCleanup

sfc /scannow



A capture of error flags from CBS.log are below:

This log clearly shows a corrupted KB.

My Questions are:

1- Need a confirmation that the corrupted KB clearly is the root cause.

2- Need a solution?
