    Amazon Windows AMIs contain a service installed by Amazon Web Services; the EC2Config service. Although optional, this service provides access to advanced features that are not otherwise available. This service runs in the LocalSystem account and performs tasks on the instance such as Windows Activation, setting the Administrator password, executing userdata, Cloud Formation Execution (requires Cloud Formation executable), writing to the AWS Console and one click sysprep from within the application. Its binaries and additional files are contained in the %ProgramFiles%\Amazon\EC2ConfigService directory. For more information about the service, please visit Configuring a Windows Instance Using the EC2Config Service.
