Windows 7 download

I'm not sure if this is the right place to post this but I'm downloading the "Windows 7 ALL EDITIONS [FULL] * Games4theworld *" torrent

Right now I currently am using a Windows 8 and Sims 2 isn't compatible with windows 8 & before I install it I was wondering if Sims 2 would read my computer as a windows 7 ? because I know it's compatible with a windows 7 & also I was wondering if I can do a dual boot ? Like have windows 8 & the torrents version of windows 7 on the same computer because , I love windows 8 but I'm really tweaking to play Sims 2 D: lol , and also are there any risks of something happening to my computer because my warranty is over with I think LMAO , anyways :newfag:

Actually, it is possible for you to have two different OS's on your computer. Here's a guide I found for you on dual booting Windows 8 with Windows 7
