Having installed (and uninstalled) Windows Intune a number of times I just wanted to signpost this blog post here that lists the components that are installed and what they do at Coretech by Brian Fahrenholtz.  The information can be found at Windows Intune Client Agent components.  It explains what each of the following does or provides:

• Microsoft Easy Assist v2
• Microsoft Online Management Policy Agent
• Microsoft Online Management Update Manager
• Microsoft Policy Platform
• System Center Operations Manager 2007 R2 Agent
• Windows Firewall Configuration Provider
• Windows Intune Center
• Windows Intune Endpoint Protection
• Windows Intune Endpoint Protection Agent
• Windows Intune Monitoring Agent

Thanks
