How to Identify Windows Version From the Product Key
- 1). Flip your computer over, either on its side or bottom side up depending on your model.
- 2). Examine the case for the sticker that gives you your operating system's product key. The purpose of the sticker was so you'd be able to re-enter the product key should you need to reinstall Windows and you lost the original product key.
- 3). Look above the product key on your sticker and the version of Windows it is for will be listed. It will tell you exactly what version of Windows your product key is for. You have now identified your copy of Windows from your product key.
