Windows 7: MS Word 2010 shows "Hidden" fonts in its menus

Windows 7 categorises some Fonts as "Hidden" (based on the language setting).



In the attachment there are "hidden" fonts showing up in MS Word 2010. Is there a setting somewhere I have missed? Or does it just not work?

As a workaround, can I just copy the fonts I do not currently want into another folder, then Delete them from the Fonts folder? Or will that cause problems?

Anyone? Is this a Windows 7 bug?

I just ran Unlocker on the hidden fonts to delete them. After a restart, they're gone.

One undesirable consequence of deleting them, is that you'll get blank unicode boxes for most non-Latin alphabets. For this, there's Code2000: all the unicode alphabets in one font instead of many.
