My Sony Vaio has been wanting to upgrade from Windows 8 to 8.1 since I bought just over a year ago. I have been avoiding it because I already hate Windows 8, and have heard horror stories about 8.1. Tonight I was half asleep and the pop up came up, and instead of clicking "Ask Me Later" I clicked yes. So what can I expect? Is it really worse and what are the problems I will encounter?
