Other people are logged on to this computer. Restating Windows might cause them to lose data.
Do you want to continue restarting?

I received this “error” after i wanted to reboot the virtual machine. The interesting question about this is who logged on to this machine. Therefore you need to run the command qwinsta
This displays information about sessions on a terminal server.

Open command prompt xxx use the ip number of the “target” server:
C:\>qwinsta /server:xxx.xxx.xxx
SESSIONNAME USERNAME ID STATE TYPE DEVICE
console admin2 0 Active wdcon
rdp-tcp 65536 Listen rdpwd
rdp-tcp#6 admin14 1 Active rdpwd


This will list the connections.
