Windows 10: No recent actions in protection history

I've had this problem for several months. At first it just showed no recent actions. But just now it prompted me for Reputation-based protection, and it still shows no recent actions when I click review to check. So, is there any way to solve this problem without reinstalling the system? Please advise...Thanks

:)

 

Protection History shows "No recent actions"

The normal behaviour is to initially open with the "No recent actions" heading then, after no more than a second (presumably while it scans its records) that changes to a list of previous actions. The window should not close on its own. That, and the hourglass when its should be reading its records, suggest that its record of past actions is corrupted.


In older versions of Defender there was a button to clear the history, but that was removed some time ago. You could try this method of cleaning out your protection history and see if it starts working again. You should probably also run a Chkdsk on your drive in case there is other corruption. SFC /Scannow wouldn't be a bad idea either.

It definitely works. This is the procedure that does indeed work.
I previously had tried deleting the folder before with no success but turning off, then on said protections is what apparently allows this to work. Thank you and the OP "LiNer2" from windows forum for this.

To anyone who wishes to try this and you don't happen to have any current protection history...
you can utilize the "EICAR Anti-Malware Testfile" to check the solution. Clear Windows Security Center (Defender) Protection History - post #8

 

Protection History shows "No recent actions"

When I go to Settings --> Update & Security --> Windows Security --> Virus & Threat Protection and then either to Current threats --> Protection History or Ransomware Protection --> Manage ransomware protection --> Block History I get "No recent actions". Then the pointer changes to an hourglass figure for two to three seconds and the window closes.

Until a few days ago I used to be able to see the Protection History or Block History after entering an administrator password. I'm using a standard user account. However, even if I do the above using an administrator account I get the same result.

About one time in ten I may actually get a result showing the Protection History or Block History. Something must have happened in the last few days, but I cannot really understand what it might be.

I'm on Windows 10 Pro v.2004 OS Build 19041.546 on a Dell Inspiron 5482 2-in-1.
