This is one more common problem of computer. When we setup Microsoft window operating system, after few time later we face this problem. This problem is like, if you start your computer, it will be take much time to open computer desktop. And when you shutdown you computer that time it will be take so many time to shutdown. When it shutdown that time it will be show don’t power off, the update is installing. I face this problem many times.
And you already in this problem but you can’t see it. Because that time you was not use internet. When you use internet that time window should automatic update and after that you face this problem. So the simplest way is off the window update. Then you never can face this problem. If want to do this then follow the step. At first go the control panel and open window updates. And select never check for update. After that it will be solved.
