Glad you solved it. You could have done it yourself using windows explorer GUI!
My commands only did:
- take ownership of everything in f:\windows
- delete all explicit permissions on the files
- activate inherentence.
Probably most of the files did actually delete on first try(?)
You forgot to populate ownership to files/subfolders(?)
You forgot to populate permissions to files/subfolders(?)
that's why I gave you the cryptic commands.
