Have you ever found yourself in a position where you never saved your license key in windows 10 and needed it? It just happened to me recently so here is a quick and easy way to accomplish.
Click on the windows key
Right click on Command Prompt and select run as administrator
$ wmic path SoftwareLicensingService get OA3xOriginalProductKey
Your output should look like the above with your license key
Pretty easy but I hope y’all found this useful.
