Can you buy Windows 7 Product keys?

Hi I have a genuine copy of windows 7 disc but the product key was 1 use only. I want to use the disc to install windows onto other computers but I need to get another product key.

Can you buy a Windows 7 product key without having to buy another windows 7 disc?

If you can where can you get them. (Im in the UK btw.)

Cheers

Off course you can!

You can either choose to buy a new physical copy to be shipped, or just a digital download + licence.

It wouldn't be any cheaper to buy just a product key, so you may as well just buy another boxed copy.
It's the product key that is the only thing that really matters. You can use any copy (of the same edition) to install Windows, you just need a product key for each installation. This is handy to keep in mind if you want to re-install Windows on a system that has the product key on a sticker, but you don't have the 'original' disk.

Ahh cool thanks as i have already got windows 7 installed on the other computer all i need is a licence which version of windows would i download? like i could get this version http://emea.microsoftstore.com/UK/en...o-Home-Premium its a upgrade key from starter to home premium. Would that licence key work on an already installed version of Home Premium.

Upgrade keys won't work. You need a key of the exact same version you have installed. That is, if the other computer has Home Premium installed, you need a key for Home Premium.

They actually fixed that from Vista to 7. Now all versions have the same x64/x86 installers so 7 will unlock the features for the version of key you add.
