hook99 is one program that will run in the background
editing the start button without making registry changes i think
and also you can edit icons and such

also if youre using a hex editor like hiew or hackman to change the start button
look for this line
There has been an enternal error in the program you were using....
that is the only instance of start you want to edit
Also if youre doing this in Windows 2k youll probably need to edit
this file sfc.dll
That file is part of the windows file protection to keep important files in their original state
so if you change it will change itself back
Here is a link to help ya
