    This is when you realize how important doing an image backup before upgrading is

    How big is the Windows.old folder? Maybe things have been deleted from it?

    You could download a Windows 8.1 ISO and use it to create a flash drive or DVD to install 8.1 from, especially if the recovery doesn't work. Windows 8 and Windows 8.1 ISO - Download or Create

    I count too much on what MS said " 30 days " .. " Dawn you MS " ..
    I can go back to wds 8.1 any time , just that it will take me long time to install all the programs and settings the way i like ..

    Wouldn't hurt to try it since you are going to clean install 8 anyway. Would be nice to know if it does work, could help others in a similar situation.

    The following conditions may cause the computer can't rollback from windows 10 to windows 8.1:
    Create a new account
    Remove the $Windows.~BT and $Windows.~WS folders required by the system to perform the rollback operation.
    tried other reduction / restore factory settings function
    Remove the verification file installation
    after a month of upgrading to Windows 10
    See Windows 10 -- : windows
    His Windows.old still there, check if it is the same reason:
    Found the reason why it happened - The answer is most likely because I used the media creation tool to download a second copy and make a bootable USB. However that second copy apparently replaces the original windows upgrade folder (~BT).
