While it’s always wise to let Microsoft keep your computer updated and secure, sometimes your apps are running well and a restart will only cause downtime to set everything up again. When you’ve run out of days to delay the restart, here is how you can disable Automatic Updates using a Microsoft approved method made for enterprise IT.
1) Press Windows Key + R to open the Run dialog, then type gpedit.msc and press Enter.
2) Local Group Policy Editor will open. Select Computer Configuration > Administrative Templates > Windows Components > Windows Update from the left panel, and open Configure Automatic Updates on the right panel.
3) In Configure Automatic Updates, change Not Configured to Disabled and save the dialog.
Now Windows won’t notify, download or install any updates. You can still install updates manually by going to the Windows Update control panel. There are more options if you change the above setting to Enable which you can discover in the help area of that dialog.
