  • Kapil, neither “Clear Contents Of Software Distribution Folder” nor stopping Windows Update helped. I still get an error message from the Anniversary update: “Uninstall this app, because it is not compatible with Windows.” But no app name is shown.
    Any idea? Thanks.

    ^^ Suggest you to download latest Windows 10 ISO (having AU) from here:

    microsoft.com/en-in/software-download/windows10ISO

    And then upgrade using it:

    ^^ Glad we could help 😊

  • Hi Kapil, can you please help me. First I tried to update to windows 10 from windows 7. It got stuck at 99%. After a reboot, I tried it again and got stuck at 99%, left it like that for 24h. Then I tried to install windows 10 from a bootable USB drive. I formatted the drive and did a clean install, but installation didn’t finish even after a day, at the end the screen goes black. When I reboot the pc, I got an error that the installation was not completed and I have to restart the installation. Then I tried installing windows 7 from USB, it installs very quick, about 15 minutes, but hangs at the last step: finalizing installation, but stays like that for hours. What more can I try? I can burn the ISO to DVD? Thank you very much.

    Kind regards,
    Toby

    ^^ I believe there is something wrong with the upgrade on your system. Considering you’ve tried all possible options, and problem still persists. I suggest you to go ahead with clean install.

  • Hi Kapil,Tried to install windows 10 home on mac mini through bootcamp asst. Downloaded ISO file, gone through partition, copy files, updates and when restarts at loop 33% error on Computer restarted unexpectedly, tried regedit, does not work. Solution please

  • Kapil Arya

    ^^ Make sure you’ve installed latest version of Bootcamp drivers. If you’re upgrading, try to make clean install instead.
