Run the command “systeminfo” from a dos/CMD window.
Outputs:
Computer Name, OS info – including version, registration info, Windows product id, original install date, system uptime, make and model of the computer.
It also shows processor, pagefile and ram useage, timezone, Windows hotfixes, and network card info.
A lo of useful information from the command line…
I’ve tested this on Windows XP and Server 2003, I would expect it works on all MS OSes, XP and newer.
Update: Does not work with Windows 2000
