    Reinstalling Windows 10 after installing Windows 7


    Hi,
    so here goes:
    If I install* Windows 7 atop Windows 10, and then reinstall* Windows 10, will it activate itself or not?


    Note - all installs are clean installs.


    Thanks in advance!

    Yes. If you are just going to reinstall Windows 10 then why would you install Windows 7 first?

    I'm having problems on Windows 10 that I never experienced on Windows 7. I've tried reinstalling and resetting Windows 10, to no avail.

    K. Since the computer has been upgraded once and activated, all future installs of Windows 10 will activate on it by retrieving the digital entitlement from Microsoft activation servers when connected to the internet - regardless of how many times you back to Windows 7.

    I just used the Reset on a Win10 Notebook and received a warning that doing so would remove the possibility [files needed] of going back to Win8.1.

    OK. How is the information stored - as in, how will it know that on this computer Windows 10 has been activated before?

    When you install Windows 10 first time, the MS activation servers register your hardware id (like a mac address but more secure).

    So next time you install it, it checks to see if previously registered and if so activates it.

    You do not need to save anything on pc.

    You can always go back to Windows 8.1 by reinstalling from scratch using MS iso.

    Alright, thanks! A little more curiosity:
    a) What exactly is the info it registers?
    b) How many times can it be activated?

    Thanks in advance!

    Re info - do not really know but it is derived from info on your mobo/bios - MS do not openly say what info, presumably to prevent piracy.

    Re. Activations - unlimited as far as I know for digital entitlement.

    If you activate using a Windows 10 key ie product key activatin, I assume it will be same as for previous versions i.e. a soft limit of 5 times, after which you will need to use telephone activation to reset the activation count to zero.
