How to know how long has the computer been up?

Start > Run, type in CMD, click OK

at the DOS prompt:

NET STATISTICS SERVER | MORE

--or--

NET STATISTICS WORKSTATION | MORE


The first line is:

Statistics since: date and time [of boot]

For single computers, (not on a network), try the workstation option, although both works for me. The | is Shift + \ on the keyboard, (UK keyboards).
