Windows Defender exclusions don’t work

If Windows Defender exclusions aren’t working, do the following:

  1. Keep the item intact
  2. Check the group policy setting
  3. Check the registry values
  4. Restart the Microsoft Defender Antivirus service
  5. Allow Windows Defender to scan archive files

To learn more about these steps, read on.

1]Keep the item intact

When you add a file or process to the exclusion list in Windows Security, the file is retrieved by path. For example, if the path of an image file named my-image.png is: C:\Users\username\Desktop\my-image.png and you have added the file to the exclusion list, you cannot rename the file or modify it the file path.

If you change the file path, you must update the list manually. Otherwise, Windows Security will rescan the file in the new location.
