Windows 8.1


Quick Review :
Includes the operating system Windows 8.1 a set of improvements and new features , which is the second crack in the operating system , and that has been taken lightly on a large scale by the reviewers and customers when he appeared for the first time last year .
MS also added some new applications , such as voice recorder , a calculator that uses modern user interface . Good calculator , voice recorder and not what it is supposed to , but it really does not need to be a full-screen application . Application -mail is new is better , and it seems more like an email client real , but we do not see users who are not tablet -making much use , because it forces you to full screen mode – unless you use the new re- multitasking quite a situation for it and let the left or the right of the screen .
Music application , now brilliant . Planning is clearer and easier to navigate and is divided things much more logically . It’s called Xbox Music , which makes some sense if you subscribe to the music service . It also gives you access to radio stations. So now everyone can get 10 hours of free flow per month.
