Linux based tools vs Windows based tools

I am not here to discuss the advantages/disadvantages of one OS over the other with regards to computer forensics.  This is more of a competition between friends as to what tools are available in the Linux world and in the Windows world to complete a specific task.  For those of you who are interesting in tools for the Linux OS, please visit my good friend's Linux Sleuthing Blog at: http://linuxsleuthing.blogspot.com/.
The battle has begun!!
