remove recent events from Protection History


I have read many ways to remove recent items from Defender's protection history but none work or only apply to Windows 10.
When I reboot these items are still listed.
I have built up quite a list over time.
Or am I better off leaving them there. I wonder why others can but I cannot; I suspect something wrong may be wrong with my system; I did get a reply from M.S. that some users are having trouble with this task but a cumulative update just came out and I still cannot remove them.
I prefer not to hack the reg as my skill level is not that good. I did follow file explorer 's folders to the end of the chain and deleted as told.
Is there some way to accomplish this?

I think that something, a program or app, broke something in Defender a while ago and so the protection history is now stored in a different location. It has to be, otherwise it wouldn't record it. Question is where?
It's still recording.

Just to compare which makes me wonder if I should clear all after scans?
Since I did a repair I have no history or service.

I tested the windows security fix and restore. I restarted the pc. After that, History\Service\DetectionHistory is still there.
You could try an in-place upgrade to fix it.

Repair Install Windows 11 with an In-place Upgrade Tutorial

Personally, I probably wouldn’t do that if the protection and scanning worked normally.

Edit: I tested that batch script which was in the first post, and it also deleted the DetectionHistory folder, not just history files
After that, I created DetectionHistory folder myself. I restored the history folders and files I deleted there. After that the defender shows up again in the protection history events. In other words, you could also try to create the folders you need there yourself, but that may not fix the original problem

I don't think so as all, except one, of my laptops have been upgraded. None have had a clean install of Win 11.

I realize I am raising the dead here but wish to clear those recent entries in protection history. -you seem successful.
Apparently you were able to clear the recent entries in protection history.
In post 16 I have the same as fabler, do you? On my last click after service I see a gray , "unknown" and delete it. I cannot clear the recent entries. I wonder if your file explorer chain is the same as fabler and mine. If so we should be able to clear it. If not there is a problem out of my control.

As I once said Microsoft told me there is the problem with some people not being able to clear protection history's recent issues.
I suspect that many who can were using 10 and upgraded not clean install. I could be wrong.
Thanks all-I guess case closed unsolved.

This one worked for me:

DefenderUI

DefenderUI significantly improves usability
& unlocks many hidden security features of Microsoft Defender.
Compatible with Windows 10 / 11 & truly free. Free 100%
and safe to use.

Delete_Windows_Defender_Protection_History.png
it boots to safe mode automatically to completely delete the protection history.
Restart to normal mode and check it out on security panel. Done
