That's right! You can turn your start button into the "begin" button, or the "Micro$oft" button, and so on.
To begin with, you will need some sort of resource editing program (not regedit, it could work, just not as easily). I would recommend ResHacker.exe, available at
http://www.angusj.com/resourcehacker. Simply extract the contents of the .zip (all to the same folder) after downloading. Then, open ResHacker.exe, click file, open, then navigate to C:/Windows/explorer.exe (be sure to make a backup copy of explorer.exe before proceeding). After opening explorer.exe in your resourse editor, navigate (in the side bar) to "String Table", then to 37 (38 if you are using the classic Windows display instead of the XP display) then select 1033 (it should be the only one there). Then look to the script display to the right. You should notice near the top the term start. Simply highlight the word start (do not include the parenthesis) and type the text that you desire. Click the compile script button, and click file, then save as. Now if you are uncomfortable with editing explorer.exe, you could always save it under a different name, then hit start, run, type regedit, and navigate to
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Winlogon, and click in the right hand display, click on Shell. A text box will appear with the file name explorer.exe already typed. Type the name that you saved the .exe as earlier, then log off and log back on again, or restart.
