Just go back to 7 for the time being. Win 8 has a number of irritating "features" and exhibits some strange behavior on certain systems.
MS has really had hit-and-miss luck with the Windows OS.
- Win 95 was ok
- Win 98 was crap
- Win 98 SE was incredible (for the time)
- Win ME was a disaster
- Windows XP was beyond incredible
- Vista was interesting to say the least
- Win 7 is still great
- Win 8 not so much
- Win 8.1 from what I can see so far looks fantastic
