How to restore the default action for File Type (Folder & File Folder). 2 PCs under my supervision have this problem:-

When a folder is doubleclicked in either Windows Explorer or My Documents, the folder will be open by ACDSee. I uninstalled the program and then it open in a separate window instead. I've adjust the Folder Option to "Open each folder in the same window" but it doesn't work. The default action for this can't be edited in File Type option. I've tried to create a new default action for it:- Open with EXPLORER.EXE; it doesn't work either.

Those PCs operated under Win XP Pro. All recent patches and updates are applied accordingly.

Is there any workaround to restore the default action for the file type (Folder & File Folder) to open in the same window?

In addition, the Recycle Bin can't open when doubleclicked from desktop. And also Windows explorer is not executed when shortcut key Windows+E are pressed. So, I create an empty folder on the desktop as a shortcut to open Folder. Does this mean I have to reinstall Windows?

I'm not sure if this will solve your problem but its a suggestion (if you are referring to windows not opening in the same window). Of course if I were you I'd back up your registry before trying anything with the registry.

HKEY_CLASSES_ROOT\Folder\shell

In the right pane, under (Default), if there is some data set then should be cleared.

Let me know if this even helps.

Your registry edit doesn't directly help me, instead your suggestion gave me an idea how to deal with it. I searched the entire registry from a healthy PC for keyword "Folder" and export a whole bunch of those registry keys. All of them resided in HKEY CLASSES ROOT only. Then I imported the keys into the problematic PC and everything worked out like a charm.
