I have been using windows 8 os from last few months. The functioning of the windows 8 os is very smooth compared to previous os i.e windows 7, windows xp. The windows 8 os has new user interface, which gives user friendly experience to the customers. The new interface comes with live tiles in replacement of start menu in earlier versions, one can download and get notified different microsoft apps with live tiles. The installation of windows is very easy, user needs to insert the os cd and run it in boot mode and then select the drive to install the os. Windows 8 has features like live tile updates, improved performance, access to download microsoft apps and games etc. Though windows 8 has good functioning and improved features it has many disadvantages. The live tile for apps like photos doesn’t get updated, i.e even if you delete media from the folder that the photos app has access to the tile still shows the photos, The second disadvantage windows 8 is not compatible with many software installations, Too many updates, no matter if you update all the updates downloaded you will be asked to download new updates within no time, Frequent rebooting is one of the major problem in windows 8, computer just reboots without even notifying, the usage of the disk goes to 100% even if there is no task running in the pc the maximum usage of disk results in decreased performance of pc which in turn puts pressure on cpu. I have fed up with updates and turned of the update service, but still the os turns it on automatically and downloads without notifying, one can’t have access to microsoft store if they have turned of update service. The service and support from Microsoft is not that good, as they have too many problems to solve they take too many months for the bugs to solve.
