Crucial.com has a utility available, Belarc Advisor, in their memory selector which audits your pc and then provides you with a webpage with the hardware details, software installed on your pc, hotfixes installed/broken, user ids etc etc. A Very useful auditing tool. The only problem is that they say its not meant to be used on corporate pc’s and should only be used for personal use. (which is a bit weird as its given on Crucial’s website which corporates would use to order more memory. Anyway, check out the utility as it is a great way of knowing all about your pc!
