Hmm, got another idea. Not sure whether it works or not but we'll see.
Idea 1: Create a new link to the Windows Explorer and set the 'Run As' property in the link properties to the local administrator. My hope is that all executables launched from within the newly linked Explorer will inherit the Explorer admin credentials.
Idea 2: Redirect the shell for users. As you might be aware, the default shell for users is explorer.exe whioch can be redirected to e.g. the command prompt or Winword, or anyy other program. So, the idea is to redirect the shell to a program that launches the actual Explorer executable under the local administrative account. Maybe you could even integrate Idea 1 into Idea 2 or use a batch file that starts the Explorer under an administrative account with SU.EXE.
