There's loads of choices for .ico files but I can't see any logic in how Windows chooses which resolution/bit depth to show

+4  A: 

There are the sizes of icons I bundle, which is the union of all the sizes you may need for XP and Vista depending on the settings the user chooses:

  • 16x16
  • 22x22
  • 24x24
  • 32x32
  • 40x40
  • 48x48
  • 64x64
  • 96x96
  • 128x128
  • 256x256

It chooses the best bit-depth your display can handle, and the icon size is a system setting stored in SystemInformation.IconSize.
