I have a script that uses the ShellExecute function to run wscript.exe in 
Windows 7 as an elevated user (with the "runas" verb). When it runs, a UAC 
window pops up and the user must click "Other User" and then enter the 
username and password of an administrative account to continue. Is there a 
parameter I can include in the script which will pre-populate the username 
box in the UAC window so the user only needs to enter the password?

Thanks...
