1. First, go to the Control Panel. This can be reached by clicking on the Start button, most often found at the bottom left of your screen, and choosing either Control Panel or Settings and then Control Panel.
   
   
2. Choose Security Center. This will show up regardless of your Control Panel display choices.
   
   
3. When the Security Center appears, look to the bottom section, under Manage security settings for: and choose Automatic Updates.
   
   
4. If your machine stays on all night, choose Automatic. If not, choose Download updates for me, but let me choose when to install them. If you choose the second, you must be on the lookout for warnings appearing on the taskbar calling for your attention. When you are informed that updates are ready to install, you must do so.
   
   
5. Click OK at the bottom of the window to finish.
