Windows is simply the best operating system for computers.
I am using windows 7 ultimate since last 3 years, it is extremely easy to install. It is of very less size and works effortlessly on low tech systems also.
I does not hang the system as it is very light. Features offered are very nice and helpful. The interface is the best part of it. It is very user friendly.
If any problem occurs then it will either repair itself or guide the user what to do. Itself check for updates. Even a new user can use it without any difficulty.
I am very much impressed by it and also reommend to others for daily purpose use.
4 out of 5 stars.
