# Description:     This script will iterate through the windows services that are set to automatic starting and alert
#                 if they don't.
# Parameters:
# -ComputerName - The name of the computer you want to check for its service (ip is okay too)
# -IgnoreList: The services that are ignored by the script (like google update services)
# -Username: The username and the domain/computer name that applies to the target hosts
# -Password: The password for the given user.
# Example:
# Get-Services.ps1 -ComputerName %host -Username "%windowsdomain\%windowsuser" -Password "%windowspassword" -IgnoreList "Service1,Service2"
