Clear Windows Security Center (Defender) Protection History

Did not work for me. After going through all steps I still have protection history full

 

Windows Security Protection History

I found the switch to turn off Malwarebytes in the Malwarebytes settings, Security tab, Windows startup.

I'm going to give Defender a try again on its own and keep you informed.

I nearly forgot to add the following. Malwarebytes did not clear the list of Defender protection history as you had indicated earlier. When Malwarebytes was turned off and Defender turned back on, guess what reappeared again? Surprise! Defender's protection history was back in full view.

I'm discouraged with Defender, but I'll give it another try if for no other reason than to add data for further analysis.

 

Windows Security - Protection History

Whoa! Hold on... I see a couple of things wrong here at a few different levels.

Command line vs. GUI: Using PowerShell to change settings in Windows Security?

So you're telling me that there is no graphical way of "setting to block potentially unwanted apps" in "Windows Security"? Even though the message is coming right from the GUI of "Windows Security"? In other words, I have to use "PowerShell" to accomplish the
task? Fancy! Now, how many normal/regular Windows users know what PowerShell is or how to use it with confidence?...

@Micrsooft: Is this some inside joke that I'm not getting? If you as a programmer present such a message graphically in the context of "Windows Security" where you rant about some setting for "unwanted apps" being
turned off, then I expect you to graphically present the option to remedy that problem. Albeit there is a contextual "Actions" drop-down menu, but it has no "off" option as presented in the message, and there is no "on" option (as implicated by the message).
So even if these actionable commands so to speak do remedy the problem (I haven't actually tried it), this is not the way to interact or communicate well with the user. There needs to be an option to flip this setting
on or off right there in the GUI of "Windows Security", instead of issuing some PowerShell command in the background.

Truths about the state of things in Windows Security and Windows

Let's try to establish some truths about what is and what isn't true about Windows Security. I invite you to correct me if I'm wrong at any point.

• "setting to block potentially unwanted apps" is equal to "PUAProtection".
  
• "PUAProtection" is equal to "SmartScreen".
  
• "Microsoft Defender" is equal to "Windows Defender Security Center".
  
• "Windows Defender Security Center" is equal to "Windows Security".
  
• "PUAProtection" is disabled by default.
  
• "PUAProtection"/"SmartScreen" cannot be changed from within "Microsoft Defender"/"Windows Defender"/"Windows Security".

Windows Defender Security Center vs. Windows Security

Here are a couple of things that are not matching in my version of Windows 10 and "Windows Security" with the linked article on Windows Central and "Windows Defender Security Center". Today is 2019-12-06, and that article was published 2018-08-20.

• There is no "Threat history" under "Virus & threat protection". I can see why. It would seem redundant to say the same thing twice: "Threat history" and "Protection history". (Pun! Protection is history!)
• There are no "Quarantined threats" under "Virus & threat protection". This is now "Allowed threats". I can see why: "Allowed" is simple English.
