Bleh, when I used to use windows...I remember there was a way to output a huge file containing everything about your pc...but can't remember how...someone remind me?
Ah, but that one is built in. Its not my specs I want to save. Easier to request the dxdiag file from someone than it is to get them to download a new program.
I like using Belarc Advisor. It's small and quick. They run it, save the results, and then give it to me. It lists all the hardware as well as the software, versions, and updates.
