Music Beta by Google is a new service to manage your music in the cloud. I don't use it very often, though, and I always prefer a clean boot when launching Windows. If you're like me, you'll like this tip. Here's how to stop Google Music Beta from automatically starting up on launch.
First, right-click on the Google Music icon in the Taskbar. Click Options.
Then, open the Advanced tab. Uncheck the box next to Start Automatically When Computer Is Restarted. Click OK.
That's it. Next time you restart you PC, Google Music Beta won't automatically start and you'll have a cleaner experience.
