You don't know about the three things that must be done after the win7 installation.

After installing win7 with the system disk (not using the ghost clone installation), often encounter such a situation: the system will automatically install the update patch when shutting down. It takes a long time to shut down; every time there is a security prompt on the Internet; the system automatically updates, causing the system to become larger and larger, and the automatic update slows down the Internet until the end of the update. In order to solve these problems, install window7 with the installation disk. After that, you must do the following three things.

1. Disable system updates, use third-party software updates (such as 360 Security Guard, Jinshan Guardian, etc.) to avoid over-large system: Enable or disable automatic update settings under Control Panel - System and Security - Windows Update For never checking for updates (not recommended).

2. Install system update when shutting down: gpedit.msc-user configuration-management template-windows component-windows update-will“do not close the windows” dialog box to display “ install update and Shutdown & rdquo; item enabled.

3. Turn off UAC (User Account Control): Control Panel - User and Family Security - User Account - Change User Account Settings Set to Never notify.
