- Click "Start" (MS Icon) in the system tray.
- Click "Run..."
- Type "msconfig" and click "ok".
- Browse the "Startup" tab to see a list of applications that load on start-up.
Be mindful of anything that you enable or disable and if you're uncertain, do your due diligence to find out what it is first.
Having said that, if you are looking to add an application to start-up, you can do so by adding that applications link to the startup folder.
