How do I make "User Group" icons larger in Win7?

[Jamestown]

How can User Group icons, on the sign-in page, be enlarged in Win7?
On a large high resolution monitor they are very small.

You can change the DPI here: Control Panel\Appearance and Personalization\Display

WHS, thanks for the reply.
However that only changes the text size within a window, not the
USER GROUP ICON displayed at Logon.

Try the last post in this topic. I don't know if it works but I'm not gonna try it on mine in the event that somethings goes wrong. Make sure to make a backup of your registry BEFORE your try this.
