Not sure if this works w/ previous versions, haven't checked, won't bother :).
Steps:
1. Get ResHacker (Resource Hacker) Download & open it.
2. Run the ResHacker.exe and open up C:\Windows\Explorer.exe with it. Expand the "String Table" on the left. Expand the "37" folder (38 for "classic" winxp style), then select the 1033 option in there. You should see something like:
STRINGTABLE
LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US
{
578, "start"
579, "There was an internal error and one of the windows you were using has been closed."
580, "Restrictions"
581, "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."
590, "Hiding your inactive notification icons..."
591, "To see the hidden icons, click this button."
}
appearing in the display window on the right.
3. Change start to whatever you want to display on your taskbar.
4. Press "Compile Script"
