Where are my icons in Windows 7?

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

"There are more than 1,000 icons in total in these files:

C:\Windows\System32\Shell32.Dll
C:\Windows\Explorer.Exe
C:\Windows\System32\AccessibilityCpl.Dll
C:\Windows\System32\Ddores.Dll
C:\Windows\System32\GameUx.Dll
C:\Windows\System32\imageres.dll
C:\Windows\System32\MorIcons.Dll
C:\Windows\System32\mmcndmgr.dll
C:\Windows\System32\mmRes.Dll
C:\Windows\System32\NetCenter.Dll
C:\Windows\System32\netshell.dll
C:\Windows\System32\networkexplorer.dll
C:\Windows\System32\PifMgr.dll
C:\Windows\System32\PniDui.Dll
C:\Windows\System32\SensorsCpl.Dll
C:\Windows\System32\SetupApi.Dll
C:\Windows\System32\wmploc.DLL
C:\Windows\System32\wpdshext.dll
C:\Windows\System32\DDORes.dll
C:\Windows\System32\compstui.dll"

The real decade-long legendary MS-DOS icons secretly reside in pifmgr.dll dynamic library file with the description of Windows NT PIF Manager Icon Resources Library in System32 folder of root of Windows contained in %windir% environment variable, that's C:\Windows\System32 by default.

"Looking for a new ICON for an application on your Windows 7 screen? Goto the bottom of your screen and click on ""Start"".

In the Search Programs and Files box, enter *.ico. Above it, you will see - ""see more results"" -select it and then select ""Computer"". Your Windows 7 search engine will then find and show you EVERY ICON that's in your computer - sit back, this might take a minute or two (you've got Icons scattered all over your computer). To put them ALL in one place, after your search engine stops, copy them ALL into a single folder and they'll always be available for you. Have fun everyone..."

"Several good answers but no one seems to have the capitalization quite right (to make copy-paste actually work).

This was my path:

%SystemRoot%\System32\shell32.dll"
