    Hello,

    I had a problem with my old Windows 10 and reinstalled the Windows 10 as a new virtual machine since there is no other way.
    However, there is an issue about Windows Activation because I have upgraded Windows 10 from Windows 7.
    So, I need to reinstall Windows 10 to same virtual machine that installed my old Windows 10.

    I have tried using DISM and Reset this PC at Settings, none of them working.

    Anyone knows how to reinstall it?

    Hi @SaehoonD
    Install Windows 10 virtual machine again. You can perform an upgrade installation that keeps your existing files or a clean installation that wipes your system drive. When you're asked to enter a key, enter the Windows 7 key. This article helps to reactivate Windows virtual machine. The installer will accept this key and the installation process will continue normally. If the issue persists, please check out this article to fix the problem.

    We are glad to hear that. Yes, if you have upgraded from Windows 7 to Windows 10 then you can use Windows 7 key to complete activation of Windows 10.
