What is Windows Defender?
Windows Defender is a Microsoft-developed security program designed to protect Windows users from malware and other security threats. It is included with all versions of Windows 10, and can be enabled or disabled through the Windows Security settings menu.
If you find that Windows Defender is not turning on, there are a few potential causes. In some cases, it may be due to a third-party security program that is conflict with Windows Defender. In other cases, it may be due to a corrupted file or settings within Windows Defender itself.

1. Restart your computer. In some cases, a simple restart may be all that is needed to fix the problem.
2. Make sure Windows Defender is turned on in the Windows Security settings. Open the Windows Security settings menu and check that Windows Defender is turned on and set as the default security program.
3. Try running a full scan with Windows Defender. Open the Windows Defender security program and run a full scan of your computer. This may take a while, but it will check for any malware or other security threats that may be preventing Windows Defender from functioning properly.
4. Update Windows Defender. Open the Windows Update settings and check for any new updates for Windows Defender. If there are any updates available, install them and restart your computer.

Be aware that this will remove any customizations you have made to Windows Defender, so you will need to set them up again afterwards.
Why is it important to keep Windows Defender updated?
Windows Defender is an important security tool that helps protect your computer from malware and other malicious software. It is important to keep Windows Defender updated in order to ensure that it can effectively protect your computer.
How to update Windows Defender
If you’re having trouble getting Windows Defender to turn on, it might be because your computer’s security settings are configured in a way that prevents Defender from running. To fix this, you’ll need to adjust your computer’s security settings.
To do this, open the Start menu and type “Security and Maintenance” into the search box. Then, click on the “Security and Maintenance” icon that appears.
In the Security and Maintenance window, click on the “Security” tab. Then, click on the “Update security settings” button.
In the Update Security Settings window, make sure the “Check for signatures on downloaded programs” and “Check for signatures on inserted media” options are both turned on. Then, click on the “Apply” button.
Once you’ve updated your security settings, try opening Windows Defender again. It should now be able to run without any issues.
What to do if Windows Defender will not update
If you find that Windows Defender will not update, there are a few things you can do to fix the issue.
First, make sure that your computer is connected to the Internet. Windows Defender needs to be able to connect to Microsoft’s servers in order to download the latest definitions.
If your computer is connected to the Internet, the next thing to check is whether or not Windows Defender is set to receive updates automatically. You can do this by opening the Windows Defender settings and checking the “Update” tab. If the “Update” tab is not visible, it may be because you are not running Windows Defender in administrator mode. To run Windows Defender in administrator mode, right-click the Windows Defender icon in your taskbar and select “Run as administrator.”
If Windows Defender is set to receive updates automatically and you’re still having trouble, the next thing to try is running a manual update. To do this, open the Windows Defender settings and select the “Update” tab. Then, click the “Update now” button. Windows Defender should then begin downloading the latest definitions.
If you’re still having trouble updating Windows Defender, the next step is to try resetting the program. To reset Windows Defender, open the Windows Defender settings and select the “Advanced” tab. At the bottom of the “Advanced” tab, you will see a button labeled “Reset.” Click this button to reset Windows Defender and restore its default settings.
