Where are my icons in Windows 7?

In previous versions of Windows when I right click on a shortcut and dived in to change the icon the initial list populated with a whole catalog of default icons.

On Windows 7 (RTM) here is what I see:

I found those icons useful when making shortcuts to web applications.

Any idea where I can find them?! I had a little "Browse..." but couldn't find much.

Edit:

You've all so far provided excellent answers, thanks - unfortunately I can't pick you all as the right one! :( Three of the files you mentioned have had equally useful sets of DLLs:

%SystemRoot%\system32\imageres.dll
%SystemRoot%\system32\shell32.dll
%SystemRoot%\system32\DDORes.dll
%SystemRoot%\System32\moricons.dll (MS DOS Icons)

Solution 1:

In the box that says “Look for icons in this file:”, type or browse to: %SystemRoot%\system32\SHELL32.dll

Solution 2:

The can be all over the place. For example, browse to this location ...

C:\Windows\system32\imageres.dll

But, they can be in any DLL, EXE or ICO file. You can also download cool ones.

Solution 3:
