Lucky windows 7 users like me and Windows 10 users who haven't upgraded.
Pull up the floor boards and tear down the house.Have you tried some memory wipe procedure using Dism++? I think Windows 10 is R2 droid needing memory wipes for perfect working.
Clean old SxS files, update cache, update history, assembly and .net cache. Reboot the machine and compile ngen with update argument for both x86 and x64 archs and you might get some options back in Settings or you should see better/faster compile times(its only a minute faster, though!)
