If you need to retrieve your Windows key to install Windows 10 (or any other reason) this simple file will do it quickly and easily for you.
I needed to retrieve my Windows key to clean install Windows 10 so I created this to share with others having the same problem.
There is no install or anything else added with Easily Retrieve Your Windows Product Key. Simply right-click on key.vbs and select "open" or double click the key.vbs file. Your key will be shown and seen in the screenshot below.
If you press CTRL + C it will copy the key so you can paste it into Notepad or your favorite text editor to save for later.
