Window 8.1 have not much effective concept than Apple operating system have . Window get hanged if I don’t get update it. It is compulsory to use antivirus where as Apple have not compulsory to download the antivirus. Window does not have much feature to use where as Apple has.
Window 7 is better than window 8.1. It is difficult to use by those user who are unknown to use computer much.I should prefer Apple os or window 7 or xp.
