As you know, the below commends in CMD and Powershell are the common way to get the product key, but this is about when the below commands are not working. --------------------------------------------------------------------------------- wmic path softwarelicensingservice get OA3xOriginalProductKey or powershell "(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey" --------------------------------------------------------------------------------- Since the above are not working, I had to download software to get it. I downloaded several and the third one worked. RW-Everything (didn't work) get-win8key (didn't work) ShowKeyPlus (Worked!) --  https://github.com/Superfly-Inc/ShowKeyPlus/releases/tag/ShowKeyPlus7060

We can cleanup Windows 10 in a very simple way by using built-in cleaner which is Disk Cleanup. We can simply type in 'Disk Cleanup' at the Start menu. Then you will open this. Now we can see the cleanup list and you can select what you want to clean. However, in this menu, we cannot clean up system files, so let's hit 'Clean up system files' button. Then we can see the below. Now we can see more comprehensive list of cleanup. Let's select what you want to clean and then hit the OK button. We will see the above image and will be finished!
