The Problem

If you’ve run into an issue where Windows Defender is not updating, it can be a real pain. There are a few things that can cause this problem, but luckily there are also a few things you can do to try and fix it.

One of the most common reasons for Windows Defender not updating is that your computer’s date and time are not set correctly. This can cause all sorts of problems with your computer, so it’s important to make sure that they are set correctly. You can do this by going to the Date and Time settings in your Control Panel.

Another common reason for Windows Defender not updating is that your computer is not connected to the Internet. This can obviously prevent Windows Defender from being able to download and install updates. So, if you’re not connected to the Internet, try connecting and see if that fixes the problem.

If neither of those solutions work, there are a few other things you can try. One is to run the Windows Defender Troubleshooter, which can help fix some common issues. Another is to reset the Windows Defender settings to their defaults, which can sometimes fix strange issues.

The Solution

If you’re having trouble getting Windows Defender to update, there are a few things you can try.

First, make sure that you’re connected to the Internet and try updating again. If that doesn’t work, try temporarily disabling any firewall or anti-virus software you have running and then try updating again. If that still doesn’t work, try resetting the Windows Update service.

To reset the Windows Update service, open the Command Prompt and type the following commands:

net stop wuauserv
net start wuauserv

After doing that, try updating Windows Defender again and see if it works.

The Results

If you run into the issue where Windows Defender is not updating, there are a few potential fixes.

First, try manually updating Windows Defender by opening the program, selecting the “Update” tab, and then clicking “Check for Updates.” If that doesn’t work, you can try updating Windows Defender from the command line. To do so, open a Command Prompt window as administrator and type the following command:

“C:\Program Files\Windows Defender\MpCmdRun.exe” -SignatureUpdate

If that doesn’t work, you may need to reset the Windows Defender settings. To do so, open the Windows Defender settings window and click “Reset Defaults.”

Hopefully one of these methods will work for you and you’ll be able to get Windows Defender updating again.
