This error is due to temporary connection related issues. Run the following FixIt and see if you still get this error.

Sometimes due to your antivirus software restricting connections, this error can happen, so make sure that you have a high internet connection. Note that running a computer without Firewall or antivirus software can put it at risk, so make sure that after you apply the FixIt resolutions, you turn them back on. Visi this link.

Delete software distribution downloads because they are just temporary files that are managed by windows update client that are actually of no use.

Use update troubleshooter Wizard which would troubleshoot and show the errors. Follow the on-screen instructions to fix this error.

Perform system file corruption check using the “sfc/scannow” command in the command prompt.

Error code “0x80072f78” is a Windows Defender error. You normally get this when you try to update Windows Defender. If you encounter this error, try using the System File Checker utility. Press the Windows key + R to bring up the “Run” dialog then type the following and then hit Enter:

sfc /scannow

Insert the Windows installation CD or DVD when you are prompted then continue. Wait until the process is complete. When it is finished, restart the computer. Windows Defender comes pre-installed on Windows 8, Windows 8.1, and Windows 10 including Windows RT and Windows RT 8.1. If you’re on Windows 7, the best to install is Microsoft Security Essentials if you want a Microsoft antivirus.

Windows Defender is also available on Windows 7 but unlike Microsoft Security Essentials which will give you complete protection, Windows Defender will only provide spyware protection on Windows 7. If you’re on Windows 7, download Microsoft Security Essentials according to your language. Now, if you have Windows Defender and it doesn’t start, the main reason is if you have a third-party antivirus installed on your computer.

Microsoft Windows is designed to detect the presence of security applications installed and when it detects a third-party antivirus or internet security program, Windows Defender will shut itself off. If the problem continues, just download the update manually.

Go to Security intelligence updates for Windows Defender Antivirus and other Microsoft antimalware and download the version for your operating system. This should allow you to update Windows Defender manually.
