Re: Windows 10 2004. Certainly seems a bit wonky + Older Nvidia Driver Workaround.
Just to update:
The start menu broke completely after applying the latest update through June 2020 Windows Cumulative Update:
"2020-06 Cumulative Update for Windows 10 Version 2004 for x64-based Systems (KB4557957)"
There is a PowerShell script to restore a broken Start Menu, but it only remembered that afterwards, so unsure if it works or not.
Again, didn't find a (quick) solution other than reinstalling Windows 10 2004 over the top of Windows 10 2004, which seems to have fixed things (for now).
I still find it odd that the least damaging way to repair a damaged version of Windows 10 2004 using an in-place "over the top" upgrade using the Windows 10 2004 ISO, is still not part of the OS. (it keeps personal info, most toggle switch settings except Cortana, saves having to lock down Privacy settings again and keeps current installed apps). Even better, would be to be able to do the same type of repair, from outside Windows in safe mode, by booting the ISO. (setup has to be run from Windows itself still).
It may not (yet) be on par with Windows 1909 in terms of the worse rollout yet but it's up there (and that wiped the contents of 'my' "Documents"), which was a shock to see an OS upgrade could still do such a thing, again only saved by a good backup beforehand.
I dread to think the numbers of people Microsoft screwed over during the 1909 update episode, that got no recompense, for those who didn't have a good backup).
This really isn't software as a service in any shape or form, Software as a disservice more like.
