UninstallBuilt-InApps.ps1

<#
	.SYNOPSIS
		Uninstall Build-In Apps
	
	.DESCRIPTION
		This script will uninstall built-in apps in Windows 10. The script can uninstall a single app by defining it at the command line. A list of apps can be read in from a text file and iterated through for uninstallation. Finally, they can also be hardcoded into the script.
	
	.PARAMETER AppsFile
		Text file to be read in by the script which contains a list of apps to uninstall.
	
	.PARAMETER AppName
		Name of the app to uninstall. This is defined when there is only one app to uninstall.
	
	.PARAMETER GetAppList
		True or false on generating a list of Built-in apps
	
	.PARAMETER Log
		Specify true or false on whether to generate a log file in the same directory as the script containing a list of all the built-in apps by their official name
	
	.EXAMPLE
		Generate a formatted list of all installed built-in apps
			powershell.exe -executionpolicy bypass -command "UninstallBuilt-InApps.ps1 -GetAppList $true

		Generate a list of all installed built-in apps and write the output to a log file
			powershell.exe -executionpolicy bypass -command "UninstallBuilt-InApps.ps1 -GetAppList $true -Log $true

		Uninstall a single built-in app by specifying its name at the command prompt. You do need to use the official name. You can get that by generating a formatted list.
			powershell.exe -executionpolicy bypass -command "UninstallBuilt-InApps.ps1" -AppName "Microsoft.WindowsCamera"
		
		Uninstall multiple built-in apps from a list inside a text file
			powershell.exe -executionpolicy bypass -command "UninstallBuilt-InApps.ps1" -AppsFile "AppsUninstall.txt

		Harcode the uninstall at the bottom of this script
			Uninstall-BuiltInApp -AppName "Microsoft.WindowsCamera"
