I run windows seven that I got from piratebay on this 12 year old computer of mine. My old HD crashed so I bought a new one and installed W7 on it, it was W7 before as well.
I have a three year old laptop and a newer computer as well, but I don't have any wifi right now and I'm too lazy to crawl under my desk and tinker with all the cables and stuff. Besides, the laptops wifi stopped working a long time ago, it ran out of battery and when I recharged it the wifi connection was gone. Haven't used it since. But I might have to try and scare it back to life now, I just found it under a pile of old things and, of course, its out of charge. I don't know where the charger is so I might have to buy a new one, and then get one of those wifi things that you plug in to the USB port. And then I'll have to go to the grocery store and use their free wifi.
Nothing is ever simple with computers, if any other product was that faulty out of the box consumer organizations would be all over their case, but for some odd reason the computer and software companys get a free card.
Win7 was available in 32 and 64 bit versions and unless you had good reasons, it would be better to install the 64 bit version. Unfortunately, now 7 has been discontinued, you are going to find things harder and harder (though there is little good reason other than Microsoft wanting more money). I was hoping to stay with 7 myself but I upgraded to newer processor and motherboard and 7 just refused to install and I had to go to 10. You might want to start preparing yourself to do the same. Though I am really not that happy about it and I'm considering finally getting back to Linux.
Yeah, it did give me a choice when I installed it, but since I don't know anything about computers I just picked one randomly. This is actually the first time I've had any problems with it.
