To Remove a Font From Windows

Click Start, and then click Run.

Type the following command, and then click OK:
%windir%\fonts

Click the font that you want to remove. To select more than one font at a time, press and hold the CTRL key while you select each font.

On the File menu, click Delete.

When you receive the "Are you sure you want to delete these fonts?" prompt, click Yes.

Note: You can prevent a font from loading without removing it from the hard disk. To do this, move the font from the Windows\Fonts folder to another folder.
