Hey guys, Just bought a new desktop without an OS. The exact same system was £100 (I'm in the U.K by the way) more expensive. And after doing some research, I discovered you could get Windows 7 for around £70. So I figured I'd save a bit of money, seeing as I'm on a tight budget. But whilst browsing the net, just before ordering a copy of Windows, I came across a number of cheaper OEM versions etc. My initial thought was that it probably wasn't a good idea to buy anything other than the distribution copy. Mainly because most of the OEM copies were available on Ebay, Amazon or some other dodgy retailer. But anyway, I just wondered what other people thought? If I am to buy the full retail copy, where is the cheapest place to buy? Also, which version is best and why? I.e, Professional, Home Premium, etc, etc??? And finally, just to clarify, if I do get Windows 7, it'll just be because it's the cheapest way to get the free upgrade to Windows 10. Am I right in thinking I can do that yeah? Any advice or information would be much appreciated. Many thanks, Steve.
