32 bit and 64 bit windows 7 license

A customer who wants you to reinstall Windows must provide recovery media from the direct OEM, because the software is licensed to the customer for use on that PC by that OEM. You cannot use your own OEM System Builder media to reinstall the operating system, or any other version of media e.

A customer who doesn't have a backup copy of the software for reinstallation will need to contact the original OEM and request replacement recovery media; you can use that media to reinstall the operating system on that machine.

You can find the product key in the battery bay on the certificate of authenticity COA , as mentioned by BetaJake. Note the the product key doesn't contain OEM anywhere. If it doesn't work, you can contact the Lenovo support and request for a bit DVD.

The product key remains the same for bit and bit releases. The product key can be found after "Product Key: " in the format xxxxx-xxxxx-xxxxx-xxxxx-xxxxx 25 digits. I think most of the folks commenting have never tried this.

They seem to be wrong!! After installing the 8gb memory, I HAD to have a 64bit system to use it all. Did the whole flash to USB, etc, then booted from my flash drive instead of media discs , and have been running 64 bit for the past week. Just today I was surprised to see a prompt for authentication, a window had popped up asking for my product key again.

I simply re-entered this product key, and it did it's thing. About 45 seconds later it said "Key accepted" and to enjoy my genuine Microsoft product. So far so good, and have found other sources say that, even with an OEM windows activation key, either 32 or 64 bit can be used with it. You wont know till you try, and you can always go back to 32 if it doesnt work.

To hell with the nay sayers I was reluctant to try, but ended up doing it thanks to your post. It also worked without any problems for me. Office Office Exchange Server. Not an IT pro? Windows Client. Sign in. United States English. Report abuse. Details required :.
