How can I remove all the paths for Toolboxes in MATLAB 7.9 (R2009b)?

I have my own functions I created when I had only MATLAB and no other Toolboxes. Now with other Toolboxes installed, functions with the same names appear in them. Without uninstalling Toolboxes, I want to "undo" the path entries so that remaining paths retain only those to MATLAB and no other Toolboxes.

Removing a toolbox path without uninstalling the toolbox would render the toolbox unusable anyway. I suggest renaming the user functions in a way that does not conflict with the built-in functions.. Otherwise, you would want to uninstall the toolboxes..
