This method of removal might not work if you have the key is hardwired into the BIOS! Because the operating system automatically picks up the license code when you boot up! In this case you can only change the key, not remove it.

But sometimes you want to give someone else your PC, or sell it to them, but you don't want to give them the Windows operating system you have activated and installed on it.

You can deactivate Windows 10, but only in an account on a PC that has administrative rights.
