My laptop, which was bought 4 years ago, has a windows 7 home premium key on its back. 2 years ago, I formatted my entire hard disk and installed windows 8. However, I want to go back to windows 7 now. Can I use the key again on the same laptop?

  • When I try to download windows from the OEM website, it says, "The Page or File You Requested Could Not Be Provided". Link: msft.digitalrivercontent.net/win/X17-58997.iso

  • When you have formatted and install windws 8 i presume that you would have lost all windows 7 key intomation. Look for the microsoft sticker (if there is one) on the bottom of your laptop. May be the sticker has the key

Yes.

As long as you use the same product version. (E.g. Home Premium or Professional)

Architecture (x86 or x64) doesn't matter with regards to activation.

Also as this is usually a point of confusion, it does NOT matter if your media is OEM or Retail. (i.e using a generic, non OEM media WILL work)

As long as the product version is correct you shouldn't have any issues with activation.

  • It did not matter. I downloaded the same product with same architecture and the key worked perfectly. Thankyou

Yes. Provided you can find the installation media for your model computer. The key will only work with the right software. A generic Win 7 installer will not work.

  • I am downloading "windows 7 home premium". This is exactly written in the back of my laptop above the key. I dont care about the drivers becoz i can manage all those. Will the key work?
