When I used the WINDOWS7 system, one time I downloaded the update, and when I was not installed, I just had to reboot the computer because of something, and I was asked if I should install and update it. If I choose to install, then I may have to wait a long time to reboot the system, delayed more important things, in order not always face this dilemma I have to think of a way.
In fact, it is easy to solve, as long as we block the WINDOWS7 system of this some superfluous hints on the line. Just run the Group Policy Editor, expand User Configuration → management module →windows update (Figure 1), and double-click the "Do not show the ' Close Windows ' dialog box to display ' Install and update '" in the right window.
The system then pops up the interface shown in Figure 2, clicks Enabled, and then the OK button saves the settings.
