The UI is suitable for the application's function of setting or deactivating Windows Defender, despite its lack of aesthetic appeal.
When you initially open the program, you'll be welcomed by a simple graphical user interface (GUI) that presents the utility's main features. It's a good idea to add the software to the 'Add it to the exclusion list' option after the first run so you don't receive any false alerts. Defender Control may be downloaded, unzipped, and then executed.
