Who's Logged On Window 7 VC Console

I am looking for a hack (ok not a hack) a script or a process or something that i am just missing? That will enable me to see if a Windows 7 VM is in use and by whom in Virtual Center. This will be helpful when doing after hours work and I am not sure if the user is logged on or not.

In XP you normally see this when an XP session is in use or locked;

But in Windows 7 all you see is:

See win7_jdoe.gif (and please dont say hit the ctrl alt del becasue that just takes you to the log screen which is blank see the next pic.

Any help or direction

Thanks in advance
