I'm planning on building my own computer but I need a operating system. I've been using windows vista for awhile and I love it. I know windows 7 is better but I don't want to buy windows 7 for $99.99.
Uhm, no, you can still buy it off of newegg. However, you've used Vista, was it on a prebuilt machine? If so you will need to buy a new copy of windows.
