How to Unlock and Toggle Microsoft Defender Settings Easily

Microsoft Defender, the built-in security tool in Windows, is all you need most of the time. While it excels as an automated tool, Defender is notoriously hard to configure manually. One has to jump through multiple menus and settings to do basic tasks like disabling SmartScreen or adding an exclusion. The developers at Voodoosoft created DefenderUI that unlocks many Defender options and settings and allows users to toggle on/off Microsoft Defender settings quickly.

Getting Started With Defender UI

How to Disable and Enable Defender Easily

Note that disabling Defender permanently is a bad idea as it is protecting your computer from all sorts of cyber attacks like viruses, malware, and ransomware attacks. Do so if you are troubleshooting something, installing a 3rd party app, or something else that’s temporary in nature.

1. Open up DefenderUI and click on the Home Page.

How to Start a Scan for Threats

Initiating a manual scan to check for threats and vulnerabilities in Microsoft’s Defender is a tedious process. DefenderUI makes it super easy and here’s how.

1. On the Home page of DefenderUI, you will see a dedicated section reserved just for scans.

3. Click on Scan now to select the mode of scanning.

The Quick scan option would do a fast scan of the most vulnerable and usual locations of an attack. A Full scan triggers a total scan of the whole system. An Offline scan would do an offline-only scan without using the internet. Custom Scan lets you select the location you want to scan on your PC. We will be selecting Custom Scan in this instance.

How to Add and Manage Exclusions

Microsoft Defender has a good system level threat detector. It however can go overboard occasionally and delete files that are not a real threat to the system. DefenderUI lets you easily manage these false positives.

1. Click on Add exclusion option on the home page to start adding an exclusion. From the dropdown menu select the option you want. We will be selecting File/Folder to prevent it from being scanned by Defender.
