When attempting to start defender in services.msc I get this message: The Windows Defender Serviceservice on Local Computer started and then stopped. Some services stop automatically if they are not in use by services or programs.

This started after today’s update 8/7/2015.

I was able to start Windows Defender Network Inspection Service but it says startup type is Manual. That doesn’t seem right.

Solution 1 – Disable and remove third-party antivirus solutions

Running two antivirus solutions at the same time causes various technical issues. Use a dedicated software removal tools to completely remove any third-party antivirus files. Restart your Windows 10 computer and start Windows Defender again.

If you don’t manage to fix the problem, you can always switch to a third-party antivirus solution. There are many great antivirus tools, but if you’re looking for a new antivirus, we suggest you try Bitdefender.

Solution 2 – Install the latest Windows Updates

Sometimes you might be able to fix problems with Windows Defender service simply by installing the latest updates. By keeping your system up to date, you’ll ensure that everything is running smoothly on your PC. Windows 10 usually downloads the necessary updates automatically in the background, but due to certain bugs you might skip an update or two.

However, you can always check for updates manually by doing the following:

1. Press Windows Key + I to open the Settings app.
2. Now go to Update & Security section.
3. Click Check for updates button.
   

Windows will now check for available updates and download them in the background. Once the updates are downloaded, simply restart your PC to install them.

Solution 3 – Run an SFC scan

According to users, sometimes Windows Defender service won’t start because of file corruption. Your system files can get corrupted and that can cause this error to appear. However, you can fix the problem simply by running an SFC scan. To do that, just follow these steps:

1. Press Windows Key + X to open Win + X menu. Now select Command Prompt (Admin) or Powershell (Admin).
   
2. When Command Prompt opens, enter sfc /scannow and press Enter.
   
3. SFC scan will now start. The scan can take up to 15 minutes, so don’t interrupt it.

Once the scan is finished, check if the problem still persists. If the issue is still present, or if you weren’t able to run SFC scan at all, you might want to try running DISM scan instead. To do that, you need to do the following:

1. Open Command Prompt as administrator.
2. When Command Prompt opens, enter DISM /Online /Cleanup-Image /RestoreHealth.
   
3. DISM scan will now start. The scan can take up to 20 minutes, sometimes more, so you need to be patient and not interrupt it.

Once the DISM scan is finished, check if the problem still persists. If the problem is still there or if you couldn’t run DISM scan before, be sure to repeat SFC scan and check if that solves the problem.

Solution 4 – Clean your registry

Sometimes Windows Defender service won’t start if there are issues with your registry. A corrupted registry entry can cause this issue to appear, and in order to fix the problem, you need to find and remove the problematic entry.
