Windows – How to launch a file properties dialog from the command line

If you logged in account is an "administrator" then you should be able to right-click cmd.exe, "Run AS Administrator", Hit "OK" to UAC, and from there the mkdir should work in Program Files without any further prompting.

If you are not a admin user, and/or open the cmd in the regular user context (not "As Administrator"), then you'll be denied access to Program Files (as you have found).

Are you sure the error you're getting (once you are successfully using a known Administrator account/ password) with RunAs is the SAME error ("1327: Logon failure: user account restriction") and not "2: The system cannot find the file specified."?

Because I get error 2 when I try to RunAs MkDir (as an admin) because Mkdir is NOT an executable file (it's a system command), and that's all RunAs can launch.

You can use CMD.EXE in combination with RunAs, and then feed it the mkdir command. This is tricky due to nested double quotes, but in the end you should be able to use:

runas /user:administrator "cmd /C \"mkdir \"c:\\program files\\foo\"\""

From any command prompt (administrator or not) to pull off what you want.

(The extra backslashes are escape characters)

You're looking for the EndpointVolume API. This is part of the new audio APIs that were released in Windows Vista, and it can be used to get or set the master volume.
... There's a complete managed wrapper library available on CodeProject: Vista Core Audio API Master Volume Control.
