    To which file are you specifically referring?

    There are two so they need to be changed back to 'windows shell'.

    Do you have a restore point before the time that you did it?

    I have tried restore, that did not work as it does not restore file extensions.

    There are normally two ways to change associations with file types. One is to right click and select "Open With" and make sure the check box is checked to always use.

    The other is go the the Start Menu, All Programs, Default Programs and select Associate a file type ...

    Not knowing what type of file or the previous extension, limits our responses.

    What file extension

    Which two

    Surely you are not actually talking about having changed the Windows Shell to notepad? It is and should remain explorer.exe
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon ->Shell->explorer.exe (should not be altered)

    I assume you are attempting to open a particular file or perhaps program and as a result of you having changed the file association to notepad.exe you are experiencing a problem doing so. And would assume also that you are receiving some type of error.
    Can you either tell us the name of the file including its' extension or perhaps the error message you may be getting?
    You may need to unhide extensions of known types to actually see the file extension in question.
    Open computer and from the tool bar select tools->folder options->then the view tab uncheck the box that says Hide extensions of known file types and OK your way back out of there. (if the tool bar is not displayed by default, simply strike the Alt Key on your keyboard to evoke it) This should reveal the file extension of the particular file you are having issues with.

    Right I understand now what I am looking for.
    I know how to change a file extension but I don't know where shell32.dll is in windows 7... It's not where is is on a 32bit system...

    A quick search of my Windows 7 Ultimate 64 bit install reveals
    shell32.dll is located in C:\Windows\System32
    as well as
    C:\Windows\SysWOW64
    and other SxS entries which I presume is where the system file checker would recover one from if it became corrupt somehow.
    Have you tried the System File Checker Utility
    sfc /scannow
    ?

    No problems with scannow.
    I know why I could not see the shell.dll now it was because properties search was set to programs and shell32.dll is not a program. That cleared up I still can't find the original file extension default...
