How do I increase memory on Tomcat 7 when running as a Windows Service?

Assuming that you’ve downloaded and installed Tomcat as Windows Service Installer exe file from the Tomcat homepage, then check the Apache feather icon in the systray (or when absent, run Monitor Tomcat from the start menu). Doubleclick the feather icon and go to the Java tab. There you can configure the memory.

Restart the service to let the changes take effect.
