But first, let’s discuss the elephant in the room: free Windows product keys.

Downloading free Windows product keys

Microsoft closely monitors the usage of product keys since they are a vital step to guarantee that only legal copies of Windows are used. As a result, attempting to find free Windows product keys is an ongoing fight. Even if you locate a valid Windows 10 Product Key on certain piracy-friendly websites, Microsoft will undoubtedly revoke and ban those so-called free Windows 10 product keys sooner or later. Even if they claim 100% activation or declare their product keys are 100% functional, or any other marketing jargon.

As a result, you should never use a website that offers free Windows product keys. These keys aren’t authentic at all. If you buy them, you may be helping fraudsters steal credit card information. Alternatively, you may be rewarding those who take use of programmes created to help children while also encouraging their closure. Furthermore, such keys are shared among users and will either not function at all (even if the websites say they are 100% working Windows 10 Product Keys!) or cease working shortly after Microsoft blacklists them.


There is no such thing as a free lunch. Instead, look for your misplaced product key. You may do so by following this simple guide.
