It shows more often after install because Fast Startup is off, so every power-on is a full start.

+Windows says a module "is blocked from loading into the Local Security Authority" + +That's Windows' Local Security Authority protection refusing another program's file, most often Apple's Bonjour (`mdnsNSP.dll`), which comes with iTunes, other Apple apps and some printer and creative apps. PowerDeck doesn't install or load anything there. It can show up more often once PowerDeck is installed: PowerDeck turns Fast Startup off, so every power-on is a full start of Windows, and that's when Windows shows it. + +- If nothing you use needs Bonjour, uninstall it in Settings → Apps. Otherwise, update the app that installed it. +- Keep Local Security Authority protection on, and don't follow guides that register the file with it. +- **Don't show this message again** hides the message. The file stays blocked, which is harmless. +
