Not that computer savvy so apologies!
I have been given a laptop with no OS and want to install Windows 7 as it's a little older and i prefer this to Win 8
I have been looking on Amazon and am getting confused reading the reviews of 'OEM' which seems to be what i don't want - seems i need a 'retail' version
Also there are loads of Amazon reviews where people say they bought it from them and it stopped working after a month saying the licence key was used elsewhere so I want to be able to buy a legit copy to install on one laptop only.
Any ideas greatly appreicated
