Windows "Uptime"

Windows XP and its brethren lack an uptime command. Yeah, the reason the probably obvious, but sometimes it would be nice to know. A user says they restarted their workstation... but most user's [including recent college graduates] don't know the difference between logging out and restarting. So how to know how long a workstation has been running?

On the command line just execute net statistics server, the line that starts with "Statistics since" provides the time the server component of the operating system has been up. In the case of a workstation this is almost certainly since the last boot.

And nope, the user had not restarted their workstation for almost three weeks.
