Microsoft Defender questions & answers

The answer to the question is that Microsoft Defender does not require a registration key.

The updates for Windows Defender are delivered through Windows Update. I didn't see any update that can be downloaded manually, which I believe this happens due to security reasons.

Make sure that your Windows Update is working normally, then search manually for updates. If there are any, it will be downloaded for your software.

Use the troubleshooting page to diagnose and fix possible Windows Update errors: https://support.microsoft.com/en-us/gp/windows-update-issues/en-us

Windows Defender is a free of charge security program developed by Microsoft that helps you protect your system and your data against spyware and other malicious applications. You can read more about its functions on Software Informer review page of the product. Also, on Microsoft Support page you can find a user guide for the program.

You use any other Anti Virus of your choice.

I would recommend MSSE. It is best for all XP, 7, 8, Vista..

You can not actually uninstall defender, however can disable it.
In Windows XP you could uninstall Windows Defender because it considers it as application that you could install but in Windows Vista and Windows 7 it is part of Windows and you could NOT unistall it. However, you could disable it.

If you are using XP, just uninstall from Add Remove program, or else use Windows® Defender Uninstaller Tool 1.0.

Although you can't uninstall Windows Defender from Vista or Windows 7, you can turn it off. To do so, click Start, type defender, and click Windows Defender. Click the Tools icon at the top of the window, then the Options link.

The rest of the instructions vary with your version of Windows:

Additional Information (on next boot):

Windows Vista monitors the use of MSCONFIG. After you reboot and login, Vista will prompt you with a box explaining that you recently made a change and explaining how to back-out the changes if desired. Below is my recommended response to this Vista System Configuration Prompt.

4. Check box Don’t show this message or start System Configuration when Windows starts and Click OK.
