Windows 10: Windows defender operational event log not updating

for some reason, the windows defender event log, as visible through the Windows Event Viewer application has stopped receiving new events. Previously, Windows Defender Antivirus would log events under Applications and Services Logs->Microsoft->Windows->Windows Defender/Operational. There, I could see when a scan started, completed, found/responded to malware, and other events.However, starting a little over a month ago, the log in Event Viewer was no longer listed under its previous location and was instead directly inside the Application and Services Logs folder with the name "Micros

Windows Defender notification of malware detection

Hello,

Thank you for keeping us posted and we appreciate your continued patience on this issue.

At this point, I suggest you to update the Windows Defender program and check if it helps.

To check for new Windows Defender definitions manually:

• Open Windows Defender.
• Click the arrow next to the Help button, and then click Check for updates. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Also, check if the detection is of the same malware file or not. Again, see if it is any specific program or a file you try to access which triggers the detection.

Additionally, view the log in Event Viewer to check if the malware is removed every time it is prompted.

To open the Event Viewer. To do so, follow the below steps.

• Go to the Control Panel and choose to click on the
  Administrative Tools icon.
• The above action will open up a new window of the Administrative Tools where you will see the
  Event Viewer.
  

You can view Windows Defender "Operational" events in Event Viewer under Applications and Services Logs -> Microsoft -> Windows -> Windows Defender.

Kindly keep us posted, for us to be able to assist you further.

Thank you.

 

Location of Windows Defender events saved in Event Viewer

In this Microsoft Defender Antivirus event IDs and error codes | Microsoft Docs.
According to the the mentioned link the generated events should be displayed at the following location in the Event Viewer:- Application and Services Logs/Microsoft/Windows/Windows Defender Antivirus/Operational.

But on performing actions, Events are getting stored at this location in the event viewer:- Application and Services Logs/Microsoft/Windows/Windows Defender/Operational.

How can I get Microsoft Windows Defender Antivirus folder at this location:- Application and Services Logs/Microsoft/Windows in the event viewer. So that events start getting stored at this location:- Application and Services Logs/Microsoft/Windows/Windows
Defender Antivirus/Operational.

Windows Updates failed to instal

I'm not sure how differant XP media center Edition is but you could clear the history \ cache if these folders are there.

Step 1 Register DLL files.

=================

By trying this step, we can check if the update engines are working properly.



1. Close all instances of Internet Explorer.

2. Click Start and Run, type "Regsvr32 atl.dll" (without quotes) in the Open box and click OK.



Note: There is a space between regsvr32 and atl.dll



3. Similarly, one by one, register the files listed below:



Regsvr32 msxml3.dll

Regsvr32 wuapi.dll

Regsvr32 wuaueng.dll

Regsvr32 wuaueng1.dll

Regsvr32 wups2.dll

Regsvr32 wucltui.dll

Regsvr32 wups.dll

Regsvr32 wuweb.dll

Regsvr32 qmgr.dll

Regsvr32 qmgrprxy.dll

Regsvr32 jscript.dll



Note: If you encounter errors while registering any of these files then skip that file and continue with the next one.



If the issue persists, let's move on to the steps below to verify Windows Update services and temporary folders.



Step 2 Verify the relevant Windows Update services.

=========================================

1. Click Start->Run, type "services.msc" (without quotation marks) in the open box and click OK.

2. Double click the service "Automatic Updates".

3. Click on the Log On tab, please ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.

4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.

5. Click on the tab "General "; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the button "Stop" under "Service Status" to stop the service.

6. Then please click the button "Start" under "Service Status" to start the service.

7. Please repeat the above steps with the other services:



Background Intelligent Transfer Service

Event Log

Remote Procedure Call (RPC)



Note: Event log service is enabled on all of the hardware profiles; this service does not have an option to enable or disable on certain hardware profile.



If it still does not help, let's proceed to step 3.



Step 3 Reload the Update temporary folders.

===================================

One possible cause is that the temporary folder for Windows Update is containing corrupted files. Let's erase all the files there to get the system clean.



1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net stop WuAuServ



2. Click Start, Run, type: %windir% and press Enter.

3. In the opened folder, rename the folder SoftwareDistribution to Sdold.

4. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net start WuAuServ
