Solved Duplicate context menu entries on folder shortcuts

[Duya]

I have a folder, called "HG", full of various folder shortcuts which I use as a custom toolbar on my taskbar, system is W7Pro@x64. (The very purpose of that toolbar is to let me access HG repositories on various folders). Recently, the folder shortcuts started misbehaving: on the context menu, there are duplicated some entries (7-zip and antivirus), and some entries are missing (by Murphy's law, one is the "HG Repository explorer", which is the very reason that toolbar exists).

However, when I open the Windows Explorer and navigate to the same folder, the context menu on these same items works just fine.

(Bizarrely, if I click on the taskbar toolbar and select "Open Folder", the context menu is wrong even from Explorer).

See the image below: on the top is the "Good" menu, on the bottom the "Bad" one. Note that on "bad" one, I have some entries which are appropriate for a regular file, but not for a folder (Edit with Notepad++, 7-zip:Open archive...).



I've done the homework and searched the net and this Forum, and a similar problem is described here:

Duplicate context entries when you right-click a shortcut

The catch is, I do have the IsShortcut entry on the lnkfile key:

[HKEY_CLASSES_ROOT\lnkfile]
@="Shortcut"
"EditFlags"=dword:00000001
"FriendlyTypeName"="@shell32.dll,-4153"
"IsShortcut"=""
"NeverShowExt"=""

A similar problem is described in this thread:

but, apparently, was not solved.

My guess is that there is an additional key in HKCR, which covers only the taskbar toolbar shortcuts, which got broken by... something (I installed a lot of stuff recently), probably missing the IsShortcut entry... but which one would that be?

Problem solved, the old-fashioned way: removed and re-added the toolbar from the taskbar. Guess we'll never find out...

I've got exactly the same problem. Same OS. Specifically I get duplicate entries in the context menu for 7-Zip and Notepad++ on File shortcuts.

However, when I open the Windows Explorer and navigate to the same folder, the context menu on these same items works just fine.

(Bizarrely, if I click on the taskbar toolbar and select "Open Folder", the context menu is wrong even from Explorer).

If I use Explorer to navigate to the real location of these shortcuts (which for me is on my D: drive) then the context menu is OK. However, if I select "Open Folder" from the taskbar (or open the same location in Explorer, which is a library shortcut, not the real location) then the context menu is also wrong.

I too think the problem might also be related to installing another app. I installed Dropbox last night and did notice that the taskbar flickered and redrew itself. I left the machine running last night and noticed the problem this morning.

However, removing and re-adding the toolbar on the taskbar has not resolved the problem for me.

In fact, the problem doesn't appear to be limited to taskbar shortcuts. As far as I can tell, any shortcut within the Document/My Documents library seems to have this problem!? However, navigating to its real location and opening the context menu does not have this problem!
