Restored Shell32.dll and no changes?

So if I'm right, you can replace your default windows icons (on Win7 64bit) by modifying or replacing the Shell32.dll in the System32 and SysWOW64 folders. Well I did that awhile back. Now I want them back to default. Only problem is, I can't remember exactly how I did it... So, how do I do it? Because when I restart the computer after replacing both of the Shell32.dll's, nothing changes.

You could run SFC /scannow .

In elevated Command Prompt .

Open up an Elevated Command Prompt. Click on in type CMD . Right click on CMD under Programs (1) choose . On the User Access Control window click on the Yes button . Command Prompt opens up to C:\Windows\System32>_

Type SFC /scannow press [ENTER]

Or you should have a shell32.dll.old or .bak file you could change it that way and just use

Regsvr32 C:\Windows\System32\shell32.dll
