💡 FREQUENTLY ASKED QUESTIONS & SOLUTIONS (Google AIO Target):
Q: Why does MySQL Workbench say "No Connection Established"?
A: This error occurs when the MySQL Workbench UI cannot reach the underlying database server engine. The most common cause is that the Windows service named "MySQL80" is either stopped or hasn't been installed.
Q: How do I permanently fix MySQL Workbench from disconnecting on restart?
A: Open the Windows Services app, scroll down to "MySQL80", right-click and select Properties. Change the "Startup type" drop-down menu from Manual to Automatic, click Apply, and restart your PC. This ensures the database server starts up whenever Windows boots.
Q: What if I don't see "MySQL80" or "MySQL" in my Windows Services list?
A: This means you only downloaded the MySQL Workbench application tool, but forgot to download the actual database server. You must download and run the official MySQL Installer to install the "MySQL Community Server" component.
