Microsoft Security Client is Microsoft’s own free security client to scan the system for malware and external attacks. The program is free of cost and and works in the background,thus protecting your system all the time. However, at times it gives the following error:
Session “Microsoft Security client OOBE” Stopped Error 0xC000000D
This error might also cause a Blue Screen of Death error. Thus, it is important to resolve this issue as soon as possible to keep your system secure.
Note: For systems using Windows defender, we need to perform the same troubleshooting for Windows defender since that would be the current security client. Eg. Kill the Windows defender process in the Task manager.
The following steps could be helpful in resolving the issue:
Solution 1] Kill the Microsoft Security Client (msseces.exe) process in the Task Manager
One reason the Microsoft Security Client program stopped working suddenly is that the process might have gone corrupt. Restart the system and check if it helps. If it doesn’t kill the Microsoft Security Client process in the Task manager.
1] Press CTRL+ALT+DEL and select Task Manager from the options.
2] In the list of processes, check for the process msseces.exe. Right-click and select End process.
3] Restart the system now and check if the issue persists.
If you are unable to find the process in the task manager, you could stop it from the Command Prompt as well.
1] Press Win + R to open the Run window. Type the command cmd and press Enter to open the Command Prompt window.
2] Type the following command and press Enter:
3] Restart the system.
Solution 2] Delete the EppOobe.etl file
1] Navigate to the following file in the File Explorer:
C:\ProgramData\Microsoft\Microsoft Security Client\Support\EppOobe.etl
Where C: is the system drive.
2] Delete the EppOobe.etl file.
3] Restart the system and check if it helps with the issue.
Solution 3] Uninstall the Microsoft Security Client completely
The reason I mentioned to “completely” uninstall Microsoft Security client is because simply uninstalling it from the Programs and features menu wouldn’t be enough.
Go to this link and download the tool mentioned in the “Fix it for me” section. Run that tool to scrape off all components of Microsoft Security Essentials from the system.
Solution 4] Disable the Program Compatibility Assistant service
1] Press Win + R to open the Run window. Type the command services.msc and press Enter to open the services window.
2] In the alphabetically arranged list, search for the service Program Compatibility Assistant Service.
3] Right-click on the service and then click on Properties.
4] Change the Startup type to Disabled from the drop-down menu and the Service status to Stopped.
5] Apply the status and restart the system.
Solution 5] Update Windows
Since it is a known issue, Windows might launch a fix pretty soon. The fix would be in form of a Windows update. We could update Windows from time to time to make sure we do not miss the same.
Solution 6] Update graphic card drivers
While the issue is with Microsoft Security Client, it’s a known fact that it is caused by faulty graphic card drivers. We could update the same as mentioned here.
