If you install from the .exe installer, you can run Tomcat as a service. There is a Services tool which windows hides various ways - just found mine under Control Panel ->Administrative tools - you should see Apache Tomcat in the list of services - it will have a Startup Type - probably now set to manual. If you select Tomcat it should show Start the service option -or- stop / restart options if Tomcat is running.
If you install from the zip snapshot you get the startup.bat etc files to run Tomcat as an application.
