Windows 10: How to force windows defender to ask me what to do with a "Threat" every single time...

As a individual who works with files that windows may see as a threat and automatically remove it is extremely annoying to have to deal with this. Is there a settings that I can choose where the files in question can be forcibly placed in quarantine and we can be asked to decide what to do with the file? I now have to go back through hours of work because something was removed and broke a program. Yes I understand there is a exception section but that does not work for me when there are hundreds of files or multiple temp areas where files will execute from and attempting to notate and enter al

Windows defender false positive - forced to allow threat

Windows defender has started to identify C:\Windows\System32\mshta.exe as a threat [normally reported as a Trojan Powessere.G]. I use mshta.exe to run an hta custom MsgBox - I have been hoping to keep using my current CustomMsgBox tool [batch file calling a vbs-hta file] until later this year when I hope to have had enough time to replace it with a PowerShell alternative.

Windows defender's notification lets me "allow the threat" but that seems to me to be a bigger security hole than is necessary - it will now ignore a potentially real intrusion when all I want to run is a genuine Windows component. My immediate problem is fixed but I would prefer to fix the false positive using the exclusions list.

I cleared the 'Allowed threats history' so I could use the exclusions list instead. I added C:\Windows\System32\mshta.exe to the file exclusions list and I checked that it had taken properly by checking the exclusions list both in the UI & in the Registry. But the exclusion made no difference, it continued to detect and block the exe.

I have repeated the attempt several times [by clearing the allowed threats list & exclusions list beforehand] and the results are the same every time
- allowing the threat works,
- using the exclusions list has no effect.

I studied the relevant tutorial but have not spotted an error in what I have been doing - Add or Remove Windows Defender Exclusions

Does anybody with experience of using the exclusions list to counter false positives have any suggestions for me?

Threats detected by Windows Defender

If you really want to be sure if those threats are removed completely then I would suggest to clean install Windows. That’s the only way to know for sure. And always disconnect from the internet next time you encounter malware. That’s the first step to take, especially if you have more than one computer sharing the same network.
