It's my life

You could do it using Computer Management. Open Computer Management on your machine (run : compmgmt.msc)and connect to Bob's computer, then right-click on Bob's computer and select Properties. Switch to the Advanced tab, and click Settings under Startup And Recovery options. Now go to Shutdown and under Action click Log Off Current User and then OK.

Of course some things are easier to do using a script:

strComputer = ""
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colOperatingSystems = objWMIService.ExecQuery ("SELECT * FROM Win32_OperatingSystem")
For Each objOperatingSystem in colOperatingSystems
ObjOperatingSystem.Win32Shutdown(0)
Next
