Unhardcode tree icons in the Registry Editor

In Windows XP/2003 regedit.exe had some shell icons integrated, namely computer icon, and open/closed folder icons. Since Windows 7 these icons were removed from regedit.exe resources, and it uses system shell icons instead.

If our regedit would use system shell icons instead of hardcoded ones, there would be three main advantages:

• Smaller size for regedit.exe
• No resource duplication in the source tree
• Better support for shell styles (theming, custom icons)

Long time ago I wrote a post in the forum about that would be good that regedit (and other apps) don't use directly some icons from a resource (from the executable). Using icons from a dll file is better, shell32.dll for example. What do you think?, greetings.
