Re: Win32_LogicalDisk Not Working Properly

You are NOT creating an "actual" session. You are creating a remote WMI
session that can "impersonate" you.

There is a session class in WMI. Look it up. Enumerate the user session
you want to view and it's associators. You have to follow that chains and
detect the class of the object. It's not straight forward. You can also
retrieve mappings from any loaded profile hive.
