.NOTES
While this script is clearly safe, if you download a file Windows may block it.
You will need to unblock it if that's the case.
Additionally, PowerShell blocks running scripts for safety. Run the command:
	set-executionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
	set-executionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

You can read more about how to use this script here: https://go.icedterminal.me/wtf

.EXAMPLE
Execute this script with a scheduled task on the process termination of wow.exe

# First move to the root of WoW. You may need to alter this path if you installed WoW somewhere else.
Set-Location "C:\Program Files (x86)\World of Warcraft"
# Stop the launcher so it doesn't freak out when permissions are being dealt with later on.
stop-process -name "Battle.net" | out-null
# Then look through for different install versions.

	# Once they are found, check the git status for untracked changes and files.

		# The path must be converted to a string.
		$path = Convert-Path $_
		# Trim the path string down to the version using regex and use that as the branch to push to.

		# Due to the bnet launcher being programmed to set its own permissions, need to make adjustments.
		# Each time the bnet launcher starts it does a permissions check. If it can't manage permissions on something it throws a fit with "Update" loops.
