Hello Handycam,
Most of them are located in the
C:\Windows\System32\imageres.dll and
C:\Windows\System32\shell32.dll files.
You can install the program
IconViewer, then right click on these files and click on
Properties, and
Icons tab. Select the icon you want, then select which size and file type (ex: ICO, BMP, or PNG) you want to save it as.
Hope this helps,
Shawn

Oops, to late.
