Most folk I know stick with 8 after installing Classic Shell or Start 8.
http://www.classicshell.net/ is free so try that first before you go driver hunting and then hunt down Windows 7.
Did you call the maker and ask if they have the instructions for this?
In closing, without the make, model number the forum can't check it out.
After 7-8 months of incessant problems, issues, and hidden menus, I cannot confortably use Windows 8. As usual, Bill has released a product that is either not ready or is poor in design. (why such large ICONS - is the country entering a phase of poor eyesight?!)
I undertstand/heard that there may be a fix to rid oneself of Windows 8 and install Windows 7. I am a XP fan, but as that is being phased out, Win 7 is its successor.
Would like to be able to rid myself of 8, and go to 7 - any recommendations ?
