Windows 10 comes with a load of apps preinstalled, and even if you remove things manually, they might come back after the next big Windows 10 update.
PowerShell can remove these Windows 10 apps as well, and you can re-run the script anytime you want to ensure that cleaned up apps are indeed removed. This line for example removes the 3D Builder App:
PS> Get-AppxPackage *3dbuilder* | Remove-AppxPackage
There is a range of websites like http://www.thewindowsclub.com/remove-built-windows-10-apps-users-using-powershell-script that provide many more examples on how to remove specific Windows 10 apps.
