Have Windows 10, pc issues, trying to go back to windows 7, to see if its just a compatability issue, has Windows 8 on pc body, has windows 7 in control panel, whatever. Has been a few months since upgraded to Windows 10, along came the problems along with it. Thought it would be very easy to do, with the recovery disk I have, to reinstall Window previous, but appears nothing is as easy as it should be. It worked with a new Hard drive. Tried to reset, restore, factory settings, boot from recovery Dvd,, its amazing, nothing works. Anyone have a simple way to do? Thanks for any help.
