Repair Install Windows 10 with an In-place Upgrade  

The previous reg file did not change the ownership or permissions of the registry key. This batch file does, then applies the reg file so it does it all.

Here is a zip file that includes SETACL.EXE. Unzip to any folder, double click on Allow_20H2_Repair_Install_Keep_Everything.bat and it should work.

Allow_20H2_Repair_Install_Keep_Everything.zip

And the final batch file:

Okay, finally got it working. Had to switch to SETACL from Helge Klein instead of REGINI or SUBINACL.

Here is the working code:

Confirmed. I took it this far, and bailed out.

Thanks TC. I had already installed both CAB files so didn't try them again. Good to know it works as advertised.

I wonder what the Windows Update version does to the registry key:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion"

Powershell Get-Acl -Path 'HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion' ^| Format-List

I can tell you one thing this .reg does that was totally unexpected. After I had run (ran?) your .bat, I tested the ISO and bailed out, I neglected to put the .reg entries back the way they were. Next time I restarted, I was greeted with the Startup Tab in Task Manager updating again! I left it and got an update this morning, also. No idea whatsoever what the relationship is, only that your .bat and it's .reg tickled the process to work again. Almost like the OS is programmatically looking at these 2 sub-keys, and somehow deciding to run the Impact calcs or not. I do not know.

I verified all this on a second 20H2 19042 and got same results. Just those 2 sub-keys was enough to trigger the results.

SO those two keys fixed the problem? That is really strange.

I don't have the problem so can't test it. I have been running with the keys set aat the batch leaves them for a couple days now with no observable affects.

- that's what's discussed in a long string of posts above where people have been working on just that... that's the latest...

Please confirm that you didn't also have this problem with earlier major builds.
