In relation to the first few posts, I upgraded to windows 8.1, fine for the first month or 2, after that my actual windows programs became really slow and barely did anything, couldn’t even get on control panel to restore it etc, left it for a while loading and managed to return to windows 8, much, much better, only thing is if you do that you have to reinstall some programmes but don’t lose your files so back up any programmes you want/ need.
