Sticker on underside of Laptop - Win7 Pro OA

[windows7r2d2]

Hi,

My laptop has the code Windows 7 Pro OA and the license key underneath, printed on the sticker.

I have a different hard drive installed now as the original wasn't very big. I downloaded the Ultimate x64 Version and it is working but will run out of license soon.

Can I use the code to activate the version installed? If not could I downgrade or alter the version without reinstalling? If not please can you tell me if I download another version which one do I need and will it just activate straight away?

Thanks R2

There is no sae/approved way to downgrade Ultimate to Pro- you'll have to reformat and reinstall using the proper media.
If you have the Pro Key, you need the Pro media (32-bit or 64-bit) although you can delete the ei.cfg file from the download you have already to enable all versions to be installed.

Thanks a lot for your help.

I tried to search for the right version and there seems to be people talking about so many. Also the pro version x64 on the Microsoft website is giving me a page not found error 404.

Is it possible to check using the code on the sticker what exactly the version should be and download that specific one? Also do you know if Microsoft are still offering the download official link anymore?

Regards

You say the sticker is for Windows 7 Pro OA?
in that case any retail Windows 7 Professional disk will work with it - either Retail (as all MS downloads are) or OEM System Builder.
Windows isn't fussy about 32-bit or 64-bit.

As I say, if you can delete the ei.cfg file from your ISO, you can create a new generalised disk which will work with the Key
