windows 7 is all wow… doesnt use up too much resources and is very quick
and as of right now you can download windows 7 (32 or 64 bit version) from microsoft’s website.. you need to have a hotmail account or sign up for a new one and fill out some questions and boom you can download it.. and use internet explorer when doing this, doesnt seem to work right in firefox (it downloads some download manager to your computer first then starts downloading the file).. yesterday, when i downloaded it, it was pretty fast with speeds up to 1.8 mbps, so the 3 gb downloaded in about an hour..
