Setting desktop font size via registry

[sam7]

Hi all,

I wrote a VB6 program that changes a lot of desktop features (like AutoPlay) and then reboots.

I want it to also change the desktop font size from Normal (96 dpi) to Large (120 dpi).

Which (Windows XP Pro) registry settings must I change to ensure that the new font size will take effect upon a reboot? I know of the following ones, but changing them does not affect the actual desktop font size on reboot:

[HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics]
CaptionFont
IconFont
MenuFont
MessageFont
SmCaptionFont
StatusFont
AppliedDPI

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontDPI]
LogPixels

Thanks a lot
Chris.
