Note: This method only applies to Windows 10 Pro edition. Given the nature of this edition of Windows 10, it’s probably advisable to leave updates turned on for security reasons.
Step 1: Press Windows key + R to gain access to the Run dialog.
Step 2: To gain access to the Group Policy Editor, type the following command into the Run dialog box: gpedit.msc and press Enter.
Step 3: Navigate to the following directory: Computer Configuration\Administrative Templates\Windows Components\Windows Update.
Step 4: Locate and highlight the Configure Automatic Updates setting in the right hand panel. Double-click to enter.
