How can I get these icons for my folders?, The blue type of the "User" folder

Like these:



I go to Properties -> Customize -> Change Icon, but that kind of folders don't appear.
I assume it's because they're in a location other than the default one: %SystemRoot%\system32\SHELL32.dll.
Fortunately, there's a browse button. Anyone knows the location of those blue folder icons? Thanks.

It's C:\Windows\System32\imageres.dll.
