I usually write quite a lot of scripts to automate tasks that would otherwise consume my whole day. I am a big fan of Microsoft PowerShell but occasionally do write a few scripts in VBScript. I uploaded one such script on the Technet Script Center. This VBScript uses the Win32_OperatingSystem WMI class to output the last reboot time of a computer specified in a text file.
The script can be viewed at the ScriptCenter Repository at the link below:
