if you want Microsoft's ImageEdit try here:

Others available as stand alone apps:
Microangello Studio can be found at http://www.impactsoft.com.
iconCraft - http://www.iconempire.com/info/vista-icons.htm
PixilShop - http://www.digitope.com/pixelshop/library/about_icons.aspx
Icon Constructor - advanced icon maker v2.2 supports Windows XP icons in 32-bit color depth with an alpha channel
Easy Icon Maker - http://www.qweas.com/download/graphics/icon_tools/easy_icon_maker.htm
Photoshop will create them too.
I need to make a 48X48 - 32-bit alpha-blended color icon.
WinZip self-extractor specifies the following: Icons must
be in the staicon file format, which can be created with
Microsoft AppStudio, the ImagEdit program distributed with
the Windows SDK. I have made numerous attempts to locate
the correct download, but it's all a bit confusing.
Please supply the precise description of exactly what
download I need to suit Windows XP. (Please - not just
patches or updates, I need a full program). Thank you. Bob
