Hello,
Thank you for posting in Q&A forum.
You can use the Group Policy Editor to disable update notifications. Please refer to the following steps:
- Press the Win key + R key combination shortcut to open the Run window, enter "gpedit.msc" in the dialog box, and then press Enter.
- Navigate to "Computer Configuration" -> "Administrative Templates" -> "Windows Components" -> "Windows Update" -> "Manage End User Experience", and find "Display Options for Update notifications".
- Double-click to open it, select "Disabled", and then click "OK"
I hope the information above is helpful.
Best regards
Zunhui
