Okay. Looks like it went well...

LOL. I like that all of the ": ("s became frowny faces.

I watched for a bit, and the first several commands appeared successful.

The ICACLS C:\Windows\Winsxs /setowner "NT SERVICE\TrustedInstaller" /T /C /Q command failed with Access is denied errors on every file. The results of the earlier commands scrolled back too far. Here's the end of it:

Shall I still reboot and run the commands from post #20? Or do we need to fix what happened here first?

Here are the results from that. Reboot now? What next?

C:\Windows\system32>TAKEOWN /F C:\Windows\WinSXS /A

SUCCESS: The file (or folder): "C:\Windows\WinSXS" now owned by the administrato
rs group.

Still comes back with Access Denied.
