Hi, RICHARD HUEY
Welcome to the Microsoft community.
To update Microsoft Defender, you can follow these steps:
- Open the Windows Security application by typing "Windows Security" in the search bar and selecting it.
- Click on Virus & threat protection on the left side.
- Scroll down to the Virus & threat protection updates section and click on Check for updates.
- If there are updates available, they will be downloaded and installed automatically. You may need to restart your computer if prompted.
If you encounter any issues or need further assistance, feel free to ask.
