Windows 7 sp1 vs windows 7 full version!

Ok, so I want to build a pc and I do not know which operating software I should get?!?

Windows 7 service pack 1 or the full version of windows 7.

The full version is around £100 more than the service pack on amazon!?!

Help!

what did I just read?!

This question belongs in the "Windows" section on the Forum.

But the diffrence between the 2 versions you talk about on amazon, they both are home premium X64 but, the cheaper one is a OEM version, and the other one, is retail, or full license.

Main Diffrence between oem and retail is that a OEM version gets linked to your hardware after activation. so you cannot theorethicly take it to a new computer wenn you buy a new one.

Retail version will not be linked to your hardware, after activation, so if you buy a new pc, you will be able to install and activate it on new hardware. "But you can only use a retail version on one PC at the same time!!"
