If you are looking for a extra everlasting option to that pesky Windows Defender, use your registry. This will close Windows Defender off for right until you manually turn it returned on once more.
Note: Tread gently while poking around the registry. A incorrect edit to the registry can cause irreversible damage to your device. Back-up your information before persevering with down this path.
1. Open the registry
Open the Run command using the keyboard shortcut: Windows key + R. Type in “regedit” and click ‘OK.’
A pop-up window may appear asking if you want to allow this app to make changes to your device. Click ‘Yes.’
2. Browse the below path
Copy and paste the below address path into the search bar at the top of the window and hit enter:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
3. Right-click on Windows Defender folder, select ‘New’ on the drop-down menu and choose ‘DWORD (32-bit) Value’
Only do this if you do not see DisableAntiSpyware in the folder. If you do see it, you can skip to step 5.
4. Name it DisableAntiSpyware and hit Enter
A new item will appear in the folder, with the text highlighted. Delete out the current text and type in ‘DisableAntiSpyware.’ Then press Enter. The item should now be saved in the folder.
5. Double click DisableAntiSpyware and change ‘0’ to ‘1’
Double-click on the new DisableAntiSpyware item. A window will pop-up to edit the DWORD. In the ‘Value data’ field, enter ‘1.’ Click ‘OK.’
6. Restart your device
Restart your Windows device to install the new edits. Your Windows Defender should now be permanently disabled.
