Windows 10, as you know, comes with over 20 built-in apps. Odds are you only use a few or none of these apps. One of the best ways to remove the built-in apps is to use PowerShell. The best part about it is that you can always restore these apps from the Windows Store should you change your mind later.
To open PowerShell as admin, right-click on the Windows Start menu button then click on Windows PowerShell (Admin). Now simply copy and paste any of the following codes to remove the corresponding app. You won't see any prompts or confirmation, so be sure to enter the correct line.
