16 COLOUR ICONS

If you select 16bit mode for graphics your icons will revert to using 8bit (16 color) icons. 

Yuck! Change the following registry setting to:

[HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics] 

• "Shell Icon BPP"="16" "
•  Shell Icon Size"="32" 
•  Setting the BPP to 16bit will yield 65565 colors for icons.
