Log parser is a wonderful and long overdue tool from Microsoft.  A new version was just released.  Log parser essentially lets you run SQL queries again SQL, CSV, Registry, Event log, File System, Active Directory and various log files (like IIS). 

Unfortunately this is not really a Microsoft product.  But there is a Microsoft product that I have mentioned before: Monad.  This is basically a *nix type shell that wraps much of the same MS stuff: AD, File System, Event log, etc.

My question is how much of overlap is there between these products.  There are lots of people that love logparser and I hope that all of its functionality and more is in Monad.
