    How to downgrade from pro to 8.1?

    I was looking around the settings and found add features. I did that and set it up. I now started it and it says I am unable to activate it, so I would like to remove it and just go back to 8.1.

    Thanks all.

    P.S. I know it's possible to activate it using a program, but I support Microsoft and would like to acquire it legally.

    P.P.S Please don't say "Just contact them" I know I can, but for the time being I want to revert.

    Windows 8.1 Pro


    If I understand you correctly, you upgraded to the windows pro pack, and need to revert back to the version that you had before?

    There is a way to do this, albeit, it is a bit unorthodox.

    You'll have to open your registry, and navigate to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion and change the keys EditionID and ProductName to reflect the operating system you want. So if you want 8.1 pro, change them to Professional and Windows 8.1 Professional, respectively.

    After those alterations, you can insert the Windows 8/8.1 disc, and run the setup from Windows. Do an in place upgrade, and you will be left with the OS you have the registration for, while keeping all your programs, files, and settings.

    *disclaimer* I am not responsible if you are in over your head and mess up your computer.
