  1. Failed Windows 10 Home activation at reinstall


    Greetings,


    My PC that was already activated after switching from Windows 7 Home to Windows 10 Home.

    Then, I accidently used Windows 10 Home > Pro tool from Microsoft Store.

    Now I've got Windows 10 Enterprise which is obviously inactivated.

    Trying to reinstall Windows 10 Home, but I don't remember my WIndows 10 Home key.

    I only got my Windows 7 Home key, but it's invalid now.


    Is there any solution?

    :)

  2. Windows 10 fails to update


    When you finish testing the Avast suggestion, make sure that you restart your machine.

    Then if the issue persists, please return to the trouble shooting list in post# 89

    I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

    [Solved] Windows 10 keeps reinstalling KB3119142

    I noticed quite some time ago that KB3119142 (Update for Microsoft Visual C++ 2012 Update 4 Redistributable Package) kept reinstalling itself for some reason. At least once daily. Sometimes up to several times a day. I just ignored it. It didn't seem to be doing any harm. And I figured they'd eventually fix it. Well...days turned into weeks, weeks into months, with no end to the problem in sight. It dragged on unsolved for at least the last few months. Literally reinstalling itself hundreds of(at least a hundred, felt like more) times in that period of time.

    So I finally googled it a couple days ago. And just got around to fixing it today. Which appears to have worked. And it couldn't have been easier to do. I feel so stupid to have let it intimidate me for so long.*Oops! Failed Windows 10 Home activation at reinstall :oops:
    Below are links to the thread that I got the fix idea from, and the official MS support info page for KB3119142(from which I quoted the above).

  4. Failed Windows 10 Home activation at reinstall

    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.
