I like to know is there a way to check the maintenance window at the client level on the physical machine. Is a way to look this up? I just want ensure it matches the collection or if it is a subset of multiple maintenance windows. 

Thanks in advance.

Why not create a report for that instead.... ?

Just found this:

SCCM Report Computers with Maintenance Window

This, along with all other client configuration, is stored in WMI in CCM_ServiceWindow (http://msdn.microsoft.com/en-us/library/jj155420.aspx)

You can use a tool like Roger Zander's Client Center also to view this info.
