Best practice is to try and have users log onto their desktop computers using non-admin creds instead of as local admins. But not everything works as expected when you are logged on as a non-admin. Here’s one more quirk along this line and how to work around it.
Log on as a non-admin and open a command prompt. Then use runas /user:administrator cmd.exe to open a second command shell running with admin creds. Type the following directory listing command to display every file on your C: drive: dir /a /s c:\
While this listing is being displayed, try to stop it by pressing CTRL+C. Nothing happens! If you ever get in a situation like this where you need to stop a command from executing, there is a way though–press CTRL+BREAK instead.
