I am currently using windows 7 and I want to ask if Windows 8.1 is worth the upgrade since I did hear that it does perform in many areas but do you think it is worth it? Also is there any way I get to keep everything I had on win 8 including taskbar settings registry settings and of course files and aplications. I want to upgrade since I am using a pirated copy of windows 7 and I want to get the legitimate copy of an OS. What do you think?
