Windows 7 Run as non admin user from command prompt

I run as admin on my machine and want to run an executable as non admin user from the command prompt (without logging off).
I'm running on windows 7 64 bit OS.
Is possible?
Thanks.

Solution 1:

If you Shift + Right click on the icon to launch the Command Prompt, you'll see the option to "Run as a different user"

You can then specify a non admin account. Anything launched from that command prompt will be executed as the user you specified.

Solution 2:

Try the Commandline: runas /user: programm.exe

This only works for .exe files in the Windows directory. For other programms, you need to tell Windows the correct path.
