Is there a way to reset permissions on Windows'
files/folders to their default values?

At present, and because I don't have much time to investigate, my quick
guess is that you have to do a Reset of Windows to make sure the
permissions get set correctly. That basically restores Windows, like an
in-place upgrade. You get to choose to keep or discard your data;
however, I'd back it up before the reset to make sure there really were
copies available. Actually I'd make an image backup just in case the
Reset ****s up.

Since that requires re-installing applications, I'd probably just try to
get the update to the newest OS level working.

Since the Upgrade install will move Windows to Windows.old,
whatever "smell" is in the Windows tree, might get fixed.

For other areas of the disk drive, I would not expect
any repair of such. For example, if you'd inadvertently
added ownerships to your own profile folder, they're
not likely to get rewritten.

The WinXP actually had some sort of script for
establishing default permissions. And you could run
that at any time (if you dared).

If you take a snapshot (with icacls) after the upgrade
is finished, you can then use that later for a (partial)
repair, where any files received after the Upgrade,
would not be in your icacls output file.

From my notes file, I also have this...

"Putting back permissions on System32 items.

cd /d "%Windir%\System32"
icacls MusNotification.exe /remove:d Everyone
icacls MusNotification.exe /grant Everyone:F
icacls MusNotification.exe /setowner "NT SERVICE\TrustedInstaller"
icacls MusNotification.exe /remove:g Everyone
"

but I really wonder if that works. TrustedInstaller is normally
delivered through a token path, a token acquired from a
service, and could an administrator actually "setowner"
like that ? Since so few things work when I try to fix
them, I have my doubts.
