In this very brief video I demonstrate how to Disable Steam from opening up or launching itself automatically on Windows Startup.
Text Instructions:
1. Open Steam Application.
2. Navigate to the Top Left corner of the Application and select "Steam"
3. Navigate to "Settings"
4. Navigate to "Interface"
5. Find the box that says "Run Steam when my computer starts" and deselect the option.
6. Select "OK" to save changes, and you are finished.
