How to Uninstall Windows Defender Updates

by Adrian Grahams

Microsoft regularly updates its free Windows Defender security program through the Windows Update feature that comes with all Windows-based computers. Windows Defender scans the computer's hard drive and automatically detects and removes malicious software and spyware. Windows Update automatically downloads and installs software fixes and upgrades for Windows Defender and other programs to keep the computer working properly. If a recent Windows Defender update has caused problems on your computer, you can uninstall it using the Control Panel.

Step 1

Click the "Start" button on the desktop taskbar.

Step 2

Click "Control Panel" and then click "Programs."

Step 3

Click "View Installed Updates" in the "Programs and Features" section.

Step 4

Locate the Windows Defender update that you want to remove from the list of installed updates.

Click the Windows Defender update to highlight and select it. Click "Uninstall." If prompted, enter your computer administrator password -- this is usually the same as the Windows login password for the main computer user.


  • Windows Defender updates contain important data files to help the program remove the latest malicious software threats. Removing a Windows Defender update from your system might make the computer vulnerable.
