Uninstalling fonts in Word 2003/Win 7?

[Doriyin]

Word 2003 has many fonts I'll never use and don't want...Constantia, Times New Roman, Wingdings, Wingdings 2, and Wingdings 3 are about the only ones I would choose to keep...all the rest I'd prefer to have uninstalled, and replaced with ones I like. Can this be done? One forum says yes, another one says no. If yes, which fonts are the 'system fonts' that cannot be removed without screwing up the OS? Lastly, how complicated and time-consuming would this be (my new tech guy is charging $100 an hour)?
