Good management of Windows 10 startup programs is important for several reasons. The main reason for adding applications, services, or scripts to the startup folder is obvious: If you use programs or processes that you need or want to run automatically when you log on, you can save a lot of time by adding them to your startup folder. I See this guide on how to “Enable or disable startup programs: How to view or change programs that run on startup”.
