  1. Reinstalling Windows 10 with same activation key


    I have on computer a Windows 10 Pro version 1607. I want to update it to 21h2. Since I cannot update it to latest version via Windows Update, I have to reinstall the operating system. The current Windows 10 was installed through an upgrade from Windows 7, it's activated, but I'm not sure if the activation key is a Windows 10 Pro, because it was upgraded from Windows 7 so I don't know if:1. Windows 7 was activated before Windows 10 or 2. Windows 10 was activated after Windows 7 upgrade. In first case, will the Windows 10 key acquired from Windows 7 upgrade be valid on a clean Windows 10 install

    :)

  2. How to reinstall Windows 10 if my computers used the free upgrade from 7 and 8?

    Will windows 10 still accept the license keys from 7 and 8 now if I reinstall my computer?

    Does Microsoft keep a list of users who upgraded to Win 10 using their 7 and 8 keys so that when users need to reinstall windows 10 the old keys would work?

    Do I need to call in Microsoft to ask them to activate my Windows 10 when I give them my win 7 keys?

    Both computers are laptops. The windows 7 machine had the serial printed on the back, and I needed to enter that when I upgraded to 10. The windows 8 machine had the serial built in inside its boot system so I didn't need to enter the key when I upgraded to 10, but I did manage to write down the keys using a fetcher program.

    Your ild keys should work but if you registered the key to your online ms persona (email address) it should be tied to your account , install without a key login with your credentials , then activate.

  4. Reinstalling Windows 10 with same activation key

    Installing Windows 10 using Windows 7 key

    Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

    As for getting rid of Windows, delete the Windows folder.
