Method 4: Using Registry Editor to prevent the alert

There is one permanent way that will allow you to get rid of the “This app is preventing shutdown” warning message. This method involves using a Registry Editor hack to program your OS to ensure that all open software which includes unsaved data will close automatically as soon as you commence the shutdown procedure in Windows.

While this makes it certain that you won’t receive the alert ever again, it also has the potential of making you lose some unsaved data if you mistakenly commence the shutdown procedure before you’re ready to.

Here’s a quick guide on preventing the “This app is preventing shutdown” altered by modifying the Registry:

  1. Press Windows key + R to open up a Run dialog box. Then, type “regedit” and press Enter to open up Registry Editor.

    Computer\HKEY_CURRENT_USER\Control Panel\Desktop

    Note: You can navigate to this location directly by pasting the location directly in the navigation bar at the top of the Registry Editor screen and pressing Enter.

  3. Once you reach the correct location, move over to the right-hand pane and right-click on an empty space. Then, select New > String value and name it AutoEndTasks.
