Exactly this for me. I simply don't want to deal with new interfaces. I feel that Windows has reached its interface peak around Win7 and Office around version 2003. Everything since has been driven by the need to justify having a team which develops new interfaces for each platform. Incidentally I feel the same way about OSX - I stopped upgrading my machine with 10.9.5. Don't like the new look and feel that there isn't anything worth upgrading to in the new version that will make me look at that candy-store like design all day long. Will hold out as long as I can - probably until I get a new machine.
