All my own video did not work, MP4 and AVI just locked up also graphics looked awful. Probably may have needing tweaking in settings, but searching via start menu was difficult. Whole resolution was thrown out. The clumsy big tiles are not for me, all the silly news feed streaming in annoyed me. Clicking on the search, just brought up things for me to purchase !
I resolved all this so easy, I just reverted back to 7. Computer is running lovely and smooth, all as was before..Heaves I sigh of relief.
Oh I do like windows 7
