Reset desktop background color

To reset the desktop background color, set the value in registry:
In XP it is HKEY_USERS\.DEFAULT\Control Panel\Colors

But in windows9x, I can't find the item "Color" under HKEY_CURRENT_USER\Control Panel\,
How should I do?

Thanks!

USE RegSetValue();

Don't set it in the registry. Use SystemParameterInfo().

Could you give me some example?

It seems that the function you mentioned can only change desktop wall paper WITH SPI_SETDESKTOPWALLPAPER

Oh, you want to change the default color? That blue?

That's something different. Hmm...

Try asking in the windows forum here

Thanks, I have figure out it.
I can add the key manually in the registry-->Edit menu or use RegCreateKeyEx() in program.
