How to Update Security Intelligence Definition Version for Windows Defender Antivirus in Windows 10


Windows Defender Antivirus is a built-in antimalware solution that provides next generation protection for desktops, portable computers, and servers.

Windows Defender Antivirus uses security intelligence to detect threats. Windows 10 will try to automatically download the most recent intelligence via Windows Update to protect your device against the newest threats.

You can also manually check for updates. A manually triggered update immediately downloads and applies the latest security intelligence. This process might also address problems with automatic updates. Windows Defender Antivirus and other Microsoft antimalware solutions provide a way to manually trigger an update.

Security Intelligence Update for Windows Defender Antivirus - KB22676

Is this new? Just got what I thought was a Defender Definition Update, but the name seems to have changed now to
Security Intelligence Update for Windows Defender Antivirus. Same KB number, same numbering sequence, just a name change. Even Reliability History show some with Windows Defender Update today, then this one just now.

Not a Platform Update, that remained at 1907.4.

Anybody else?
