Running thread with different permissions

[a6amsunrise]

Running XP, i dont log in as admin all the time, but one program i wrote needs to have admin permsission. Normally i use the
RUNAS /USER:a6amsunrise C:\pyprogram.exe
command, but is there some win api function that will just escalate privileges by itself? Like a runas(functionname/thread, username, password)?

Yes, take a look here: Client Impersonation (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/client_impersonation.asp)

Thanks, that wasnt exactly what i was looking for, but it led me to this:
