Like others running Windows, I have been dutifully updating Window Defender the last few days with a fix for a critical bug. The update procedure is simple. Open the Control Panel, click on Windows Defender, and then check for updates.
The only thing out of the ordinary, on Windows 7, is that the update check is hidden behind a downward pointing triangle just to the right of a white question mark (this is not true in Windows 8 or 10). The “about” panel is also here. If the Engine Version is less than 1.1.13704.0 then it needs to be updated immediately.
