That's not Wingdings, that's Marlett.ttf - the font used to display windows elements like the min, max and close buttons. This one should never be choosable in any font list.
Can you go to Display Properties - Appearance - Advanced and try to change the menu font to something else.
Did you do any changes related to fonts or more generally asked what did you do before the problem appeared?
Can't you just restore the fonts from your Windows cd?
Insert the cd into the drive, open a command window and
(assuming E: is your cd drive and Windows is installed in C:\Windows - otherwise adjust)
expand E:\i386\*.tt_ C:\Windows\Fonts /r
expand E:\i386\*.fo_ C:\Windows\Fonts /r
EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
