Hi, I was troubleshooting something on Windows 11 build 22000.282 and I messed up with Servicing/Packages mum/cat files (specifically all hyper-v related) and wanted to reset the original files through

sfc /scannow
dism /online /cleanup-image /checkhealth
dism /online /cleanup-image /scanhealth
dism /online /cleanup-image /restorehealth
sfc /scannow

but that likely didn't do anything, it just kept saying "No component store corruption detected"
I thought then to dism remove-package for all hyper-v components, and then pulling files from a install.wim (same build) to Servicing/packages and then dism adding packages again.
well, that made windows optional features window blank.

I went to uninstall the last update rolling back to build 22000.258 and in that build, optional features was working fine except it didn't include hyper-v, hypervisor and virtual machine platform. Hyper-v tools also went missing from Windows Tools.
It is like it got completely uninstalled, I didn't know how to restore hyper-v based features, and by looking in the web, I didn't find even any similar issue.

I ran:
sfc /scannow
dism /online /cleanup-image /checkhealth
dism /online /cleanup-image /scanhealth
dism /online /cleanup-image /restorehealth
sfc /scannow

again for a chance to get everything back to normal but it stayed the same.

please I need some help here, I am not an expert, I was trying to fix a weird issue in the first place, that makes Windows 11 moves the date to year 3209 somewhat often when any hyper-v feature is enabled, I thought by replacing those files in Servicing/packages with a build of Windows 11 that has no issue related to year 3209. And then it all went bad. I wasn't messing up for no reason.

Anyway, I don't want to end up with a clean install, so that's why I am seeking help here.

Thanks.

in Windows/Servicing/LCU there is a rollup fix amd64... for my current build which is 22000.258 and by looking for those mum and cat files I did find some related to hyper-v, how can make use of that file?

Welcome to Eleven Forum.

You could try an in-place repair upgrade.

Or you could try System Restore first as it is a bit more straight forward to do.

Ok, by restoring system do I need an ISO with same version?

And still wondering how to fix this issue, I reported it to Microsoft, it is told to be fixed on build 22478 but it didn't came from Microsoft, nor was it in the changelog/news wire, some dev insider told me?
What could be the cause of the issue and how to solve it?
It happens also to the recent insider builds of Windows 10 and I am afraid it could affect Windows 10 21H2
