How to disable Windows Security Center

Windows Security Center helps you to protect your computer, especially by giving you notifications about important security risks. But sometimes it's also a great annoyance, when it keeps giving out warnings that you already know. Here is how to disable it:
1. Click on Start button, then select Control Panel.
2. Select "Administrator Tools" (if you don’t see it, double click on "Performance and Maintenance" first).
3. Double click "Services".
4. Find and right click on the service named “Security Center”, and select "Properties".
5. In the "General" tab, beside the "Startup type:", change the setting from "Automatic" to "Disabled". This will permanently disable Security Center forever.
6. Reboot your computer or click on "Stop" button at the bottom of the dialog window to stop Security Center immediately.
