Reliability Monitor is blank

I check Security and Maintenance\Reliability Monitor every so often but recently it has completely stopped showing reports/events. It used to show minor app crashes and events like Windows Defender updates but now shows nothing. I cleared "reported problems" hoping it would reset but still nothing, though the graph line still appears.

A sfc scan did find issues but I cant repair them. The log file indicates a problem with Windows Defender and it somehting I found others experiencing after a search online.

The system runs fine otherwise. Any help appreciated

That Defender problem in SFC is actually a bug, now corrected by the latest Defender Antivirus platform update. You need to use DISM's RestoreHealth option, restart, then use SFC again to fix this. Whether or not that will also fix your reliability report problems remains to be seen.

Use DISM to Repair Windows 10 Image

Well, does anybody know what the hell happened here - yesterday?



Only failures are suddenly shown in the whole period.

And before you ask: although I do use CCleaner I did not clear any logs (do not have habit of doing so).

SFC and DISM are obviously returning fine results as well.

When you select the flagged date,12/06/2020,what shows up in the details?

It may be working normally, but does not report everything it should.

Please see how it does pan out on my laptop:

As you can see in case of my main PC so-called 'information events' and 'warnings' are suddenly missing.

Defender and perhaps Ccleaner are the problem,not Reliability monitor.
When you ran dism,as recommended by Bree,what report did it give?
Try ---dism /online /cleanup-image /restorehealth---
Go to Settings>update etc>check for updates and see if Defender is fully functional.If it does not give security updates and dism hasn't given any errors,then give serious thought to a clean install.
Use Macrium and a USB HDD for the image before clean installing.
The use of third party programmes,Macrium excepted,is no longer necessary because of the numerous tools included with Win 10.The practices of XP etc. are over.

Appreciate your input, but had your read my previous posts you would have seen that SFC and DISM report fine results.

I also entirely fail to see what Defender has to do with this situation (and yes, it does update itself fine as well).

As you dropped 'clean install' bombshell which is never a solution to such rather trivial but no doubt annoying problem at all, I think I will await rather more creative input if you don't mind (notwithstanding investigations my end that continue in the background).

Your courteous reply is noted.
In Post 1,para 2, you claimed a problem with Defender.
In para 2 stated it was continuing.
Nowhere in subsequent posts was it ever "fixed".
The "obvious" operation of dism is not obvious via your posts.
Reliability Monitor is reporting faults,as it should.Defender carries out the downloading,Monitor only confirms success or failure.
Should Defender not operate normally,neither will Monitor.
