windows defender not showing the quarantined files

Right-click on the Start button and select Windows PowerShell (Admin) (if it’s not in the menu, you can right-click on the taskbar; select Taskbar settings; and then add it to the menu) – or –search for PowerShell and then right-click on the listing and choose Run as administrator.

Now copy, paste, and enter this command at the prompt:

Set-MpPreference -DisablePrivacyMode $true

See if that changes the game.

I can now view the items in the History tap of Windows Defender.  Hope this change doesn't affect any other functions.  For example, will future updates to this version of Windows still work OK?

Unfortunately, when I got back to testing this today, I found that the error will come right back again whenever we try to actually do something in the History tab – so that was a dead end; and it looks like we’ll just have to wait for a bug fix for the old interface. But the old interface is already on its way out, and we really need to concentrate on the new interface:

Since the default action for the eicar.com test file is now removal, and since Automatic Remediation is enabled by default, I wasn’t able to start testing the basic functionality of the new interface without first turning off Automatic Remediation. So far, I don’t see any serious issues with the Scan history page in the new interface – and the new interface is hopefully going to be the best workaround for any and all problems that we find in the old interface.
