Hi there i always google and i always look extensively but 3dGame man is always the place i can trust for answers.
So i am a PC builder starting out as a company and i want to know if i get a OEM version of Win7 64-bit Pro Can i upgrade my hardware (anything but my HDD) and still use that Disk to reinstall or repair etc.?

  • **An OEM operating system is registered to the system it is originally installed on and the support for the software is handled directly by the installer and not Microsoft or ourselves. You cannot transfer this software to a different PC once activated. We recommend the purchase of retail software if you plan on upgrading major hardware in the future.
Thats what scares me. This copy would be for my home computer and i know i dont get the phone call service free but do i get updates and service packs etc. What are the troubles i might experience as a Hardcore gamer/Customiser/Victim of Virus's/Video Editor?
Any help would be great, thanks.

It's basically the same as the retail version with all the updates but if you change hardware a lot you may get some "This copy of Windows is not legit" messages and then you'll need to call MS for them to reactivate it. You also can't re-install it on another computer if you no longer need the license, can only be re-installed on that same computer.

Yeh i heard that but how major do the changes have to be before i get that kind of message? And if i bought OEM but im not a registered computer builder yet will they have a problem or will they help me out?
And im planning on using this copy only for me.
Also out of interest how does it know its only allowed to be copied onto your computer if the SID and any other personal stuff is wiped? Thanks for the reply.

Bugger. The hardware section has always been more active.

I've changed hardware before and YES, you do get a "This version of windows is not genuine" message but all you gotta do is go to the MS website and download and install some genuine checker software and you're good to go. If you change hardware alot then you might have to call MS.

Also if you're a system builder there are discounts when buying windows 7 in bulk
