I'm about to format my XP installation I have had on for years.

How can I find out how long its been on? Just curious to know really since back in the day Win 98 was reinstalled about once a month and this has been on atleast 2 or 3 years.

Hmm system info tells me I installed on January last year. Im pretty sure thats wrong.
