Installing PCSchool with UAC enabled – Mapped Drive Security Issue – Windows 7
Previously some users had to turn off UAC for the install of the PC School client or couldn’t see the mapped drive when trying to browse to the PC School server location. If UAC was turned back on after the install, then wsautoup wouldn’t work. Wsautoup runs from the server rather than the local client.
Local administrators are given two security tokens at login, a standard user token that is used by default plus an administrator token that is only used when you answer Yes to an elevated privilege prompt. One of the issues with mapped drives is that in certain scenarios the standard token is used when in fact you want the administrator token to be used. There is a registry key you can add to get Windows 7 to use the administrator token as desired.
Add the new registry key as per the linked article below, reboot, then log on as the local administrator. Do a standard PCRemote2009 install to C:\PCSLaunch and you should still be able to see the mapped drive as the server location during the client install (with UAC on). After doing the standard copy of the license files, start PC School and wsautoup runs without a hitch.

It is probably easier to roll this out with a group policy
