To test a list of CLSIDs use test_clsid.bat.
NOTE All our tests were conducted impersonating the
NT AUTHORITY\LOCAL SERVICE. To have a shell as
NT AUTHORITY\Local Service, use
psexec (as Administrator)
.\PsExec64.exe -i -u "nt authority\local service" cmd.exe
Some CLSIDs impersonate the current logged-in user in first session, interesting if the DA is logged in ;-)
