Uninstall VMWare Fusion and VMWare Tools on boot camp partition
Uninstall the VMWare Tools in the VM using the uninstaller in Add/Remove Programs
Use the Fusion uninstaller on the installation DMG to remove VMWare Fusion
Follow this VMware KB article to clean up Fusion completely.


Sidenote: I can't find an official KB article for removing the tools, and those I do find all only mention Add/Remove. I am assuming it does a complete removal.
