The first is only one i can find a registry or dll with it, i try changing a icons equal to this in imageres.dll but had no effect.

The second i know that are in shell32.dll, but when i edited, replace and restarted my pc the only program i can start is explorer and the icons still the same.
Maybe there is other way to replace then (maybe via regedit) or a better way to edit shell32.dll.
I tried with Resource tuner.
