[tex-live] Windows: admin installed vs non-admin installed

I had a chat with one of the windows admins. ACL is the way to go, I think they are going to control it via AD somehow.
I did a test on a standalone win7 just to test it.
The key group is the pseudo group "Authenticated users", on my Win7 it has the same permission as "Users" plus "Allow Write". Removing that "Alow write" is a bit hairy (note that using "Deny write" is not a good idea as then even admin cannot change the files), but here is how I did it in a vertual win7 just as a reference for others
right click on c:\texlive, properties, security
Choose "Authenticated users"
Hit the advaned button
Under the "permissions" tab, again choose "Authenticated userrs", also
remove the tick mark under "Include inheritable permissions from object's parent" (otherwise we cannot edit it)
now press "Change permissions"
Again choose "Authenticated user" and press "Edit"
For my test I gave "Allow" to the following entries
Traverse folder / execute file
List folder / read data
Read extended attributes
Hit OK/Apply all the way back out.
Now tlmgr can only be executed via run as admin or via admin dos promt, normal users get a read only error.
Seems to be a good solution for computer labs.

Yes, this is a loophole. The UAC prompt was only intended for
accidental mishaps, but I can understand that for a computer lab it
is not good enough.
Look at the icacls command-line utility to set the ACL (access
control list) for the TL directory.
