Unofficial third-party Windows tools and utilities are pretty popular among Windows enthusiasts. However, these tools can often break certain aspects of the OS. Recently, a popular Windows 11 debloater app was found to be causing conflicts with the operating system. Although the issues were seemingly fixed, the app has been banned from the Microsoft Store which led the developer of the app to call it "a tragedy".

In a somewhat similar situation, developer of another third-party application, Defender Remover, has confirmed that their app was indeed causing issues with Universal Windows Platform (UWP) apps. Good thing, though, is that the issue has been resolved in the latest version, 12.4.1. They write:

- update: this uwp issue is caused by unregistering classes of windows smart screen, so that is needed for uwp functionality (sometimes). The class which i'm talking about is SmartScreen Settings Checker. The next version of Defender Remover will not unregister SmartScreen anymore.
- fixed in 12.4.1

According to my experience, some removal on ISO:s get reinstalled when updating the system. When removing Ms Defender with NTLite either on ISO or running Os, it gets reinstalled at the next update. How is it with this tool?

With NTLite you can remove it over and over on a live Os, this tool is pointless if Defender gets reinstalled since there is no way to remove it, again.

Oh no.. Shocking.
Of course those things can do that sort of thing. That's why I never use them. You should never remove a part of the OS just like that.
Why would anyone want to remove defender anyway, just turn it off completely by installing other AV.
