# Windows AMIs don't have WinRM enabled by default -- this script will enable WinRM
# AND install 7-zip, curl and .NET 4 if its missing.
# Then use the EC2 tools to create a new AMI from the result, and you have a system 
# that will execute user-data as a PowerShell script after the instance fires up!
# This has been tested on Windows 2008 SP2 64bits AMIs provided by Amazon
# 
# Inject this as user-data of a Windows 2008 AMI, like this (edit the adminPassword to your needs):
#
# <powershell>
# Set-ExecutionPolicy Unrestricted
