It is possible to downgrade from Windows 8 to Windows 7, but on a tablet, it may be trouble. For one thing, a tablet does not have a disk drive at all, so a Windows 7 CD could not work. If you managed to download it from Microsoft.com and manage to downgrade, Windows 7 is not as optimized for touch screens and tablets as Windows 8. So all in all I am not fully sure, but Windows 8 is really not all that bad. Do you have Windows RT or Windows 8? (Windows RT does not include desktop mode).
