I also have quite a long time is one of those who bothered to the new operating system from Microsoft for the so-called Modern UI. Meanwhile, however, I must say that to me as a normal PC user, the concept like. I use the example often News, Mail, Calendar, or Skype, and I think the tiles have a good utility to quickly and easily obtain information or time to look just like the weather is. Therefore, I have the optional boot directly to the desktop but not enabled Off always with the tiles. Also with the mouse they are good to use. With the update to 8.1, some visual and functional improvements have been implemented, for example, I find it very nice, on the Modern UI the same as on the desktop background to have. The new Start button brings naturally the corresponding Start menu from Windows 7 does not return, but provides for a right mouse click some system control and logout options, as well as the desktop acts thus again somehow completely. The main programs that could be used to reach the Start menu will now simply pinned on the home page and can be reached so quickly. Even the new, somewhat flatter design pleases me now pretty good, I just wish that the folders and icons had been designed in the new 8-style. The Windows Defender is now a solid antivirus equal on board and performed in the background his service. In addition, the file version history will regularly back up the libraries represent a positive innovation. For the operation, I can only say that Windows 8.1 is swift as an arrow, it starts in zero-comma-nothing and goes down as quickly. In conjunction with an SSD has so rapid BS, which barely provides increases in speed. Even hardware conflicts there were not with me, but where I also have a relatively current system in which all drivers are available. The installation went anyway without any problems. All my programs and run to play, I can not say anything because I'm not a gamer. All in all, I find the new Windows 8.1 really succeeded, it's become such as Windows 8 from the outset should have been. Anyway, I have now but said goodbye after a long delay of Windows 7 and can give the new Windows with a clear conscience 5 Stars.
