[H] Vista batch file elevation

[Thane Sherrington]

Is there a way to have a batch file launch a second batch file at an 
elevated privilege level?  I have a batch file (named "runme.bat") 
that calls a batch file that does some registry changes, and I'd like 
the runme.bat to call the second at an elevated privilege level (and 
ask the user once to allow the elevation rather than multiple times.)  I tried:

runas /user:administrator fixit.bat
 but then the system asks for an administrator password and there isn't one.

I know that I can right click on RunMe.bat and choose Run as 
Administrator, but that's a bit clunky.
