4. MSKeyViewer Plus

During my test, I felt MSKeyViewer Plus has outdated design but the developer-focused more on compatibility and user experience. MSKeyViewer Plus works flawlessly and recognizes the Windows operating system and Microsoft Office product keys, and provides proper information on it.

You have two options available, 1) Copy selected information to clipboard and 2) Copy all information to the clipboard. Either way, you can copy and paste the Product Key information to notepad and use it later. However, I haven’t found newer updates and sometimes it fetches incorrect Product Key, but this is a good alternative to find product keys.
