Describe the bug Windows Defender can detect FanControl.sys and remove it so the app no longer works.

With no ability to restore or exclude other than using complex options.

"Your administrator has....", so you are not admin on that machine or you are part of an enterprise domain?

I noticed that too, the user is Admin. Windows Defender just acts and deletes the suspected file.

Can't you whitelist it?

Nope, no easy option for that except for complex manual methods: Add exclusions for a false positive.

The problem still exists in V186 on Windows 10. https://www.defenderui.com/ - ASR - Change the "Block abuse of exploited vulnerable signed drivers" to audit mode seem fix it.
