How do I manually update Windows Defender virus definitions?

Microsoft Defender Antivirus and other Microsoft antimalware solutions provide a way to manually trigger an update. In Windows 10, select Check for updates in the Windows Security Virus & threat protection screen to check for the latest updates.

Does Windows Defender automatically update?

Use Group Policy to schedule protection updates

By default, Microsoft Defender Antivirus will check for an update 15 minutes before the time of any scheduled scans. Enabling these settings will override that default.
