deleted some fonts -- wrong ones

Archived from groups: microsoft.public.windowsxp.configuration_manage (More info?)

I deleted a bunch of fonts to free up system resources and make font
selection in worf etc easier.(XP Home). Now the (formerly grren) "Start"
button on the lower left of the screen is in an ugly font and doesn't have
the pretty grren color.
Also, the "Help" screen is now in a serif font.

Does anybody know which fonts are essential for those things to look like
the original, and is just re-installing enough to make things look like
before again?

Thanks for any help.
