Restore right-click menu on taskbar icon in Windows 10

SCENARIO


I've been customizing a Windows 10 TH2 ISO image using the WinToolkit application, and manually using DISM to remove features and packages from the mounted Install.wim image, I also removed from the WinSXS directory specific unrequired files for my needs on which I'm not interested and are safe to be removed, like for example a bunch of TTC and TTF font files, Skype, OneDrive and WMP file references, Metro Apps, drivers, shortcuts, etc.

After I'd customized the WIM image, I installed the O.S. on a virtual machine (VMWare Workstation), and I was working for weeks on that V.M. by installing custom apps, 3rd party themes, and reducing a little bit more the space on disk because my intention was to capture the modified partition with DISM with all the customizations applied to generate a new Install.wim so in that way I can burn a Windows 10 ISO with all my programs installed by default and the system personalizations I did.

  • To clarify:

    I'm not a Windows gurú, but I consider that thanks to the experience of years I have decent, good, almost advanced knowledges in general, about the Windows filesystem.

    This is not the first time that I realize this task, I've successfully done the same work with Windows 8/8.1 and Windows 7 in the past. More than that, currently I'm on a Windows 8.1 from 2 years ago modified by me with the same methodology with a lot of things deleted (some safe, some unsafe) and without issues of any sort.

PROBLEM


The problem I discovered is that due to the modifications I did, when I do right-click on a taskbar icon, this menu doesn't appears:

( I mean the context-menu of the image with pinned folders and "Close window" item, etc, the entire context-menu. )

Instead of that menu, nothing is shown, just nothing happens when I do right-click on a taskbar icon, however, the thumbnail preview and the other cms (like the start button cm) are working.

As I said, I was working for weeks on the V.M. customizing my Windows 10, and I discovered this annonying issue at the last day of all this work, so "rolling back" to waste a couple of weeks again is not an option for me.

QUESTION


I would like to ask for advanced users in Windows debugging to help me debug what is happening when the user do right-click on a taskbar icon to discover what is the cause of the missing context-menu. I don't know if maybe apps like Process Monitor from SysInternals or Spy Studio from Nektra could help me to discover and fix the issue by examining windows calls and events, I need orientation in this way or someone who could do it for me.

Or I ask for what files or packages or registry values or dependencies in general are required to that contextmenu to be shown, then knowing that maybe I could restore/copy the missing things from a working O.S. to the non-working O.S..

Please note that I could try any thing with any risk of O.S. corruption because I work with snapshots in the V.M. that I can restore to a previous O.S. state if a possible solution fails.

RESEARCH


( To avoid confusions, I will name "non-working O.S." the customized O.S. on the V.M. that has the missing context-menu, and "working O.S." the O.S. on the V.M. that has the context-menu working )

After I discovered this problem, I generated a Windows 10 ISO with WinToolkit without this annonying issue, then I've installed that "working" O.S., in a new Virtual Machine and I was trying a couple of basic possible solutions, like these ones:

  • Copy the entire contents of WinSXS folder (and all the other system folders like program files, appdata, etc) from the "working" O.S. to the non-working O.S., this way I tried to restore missing deleted files of the non-working O.S. that maybe were required for the context-menu to be shown.

    Unafortunately this methodology didn't solved anything.

  • Export all the registry keys of all registry root keys from the "working" O.S. to the customized O.S.

    I was unable to import the HKCU root due to registry user-permissions, but I imported the HKCR, HKU, and HKLM (not all keys, registry user-permissions again), but the problem was not solved.

  • I'd enabled and ran all the Windows services of the non-working O.S.

    This didn't solved the nothing.

  • On the non-working O.S. I tried desesperatelly the Windos Repair application, also CCleaner and Wise Registry Cleaner.

  • I'd uninstalled all the custom apps, codecs, etc of the non-working O.S., I can completely discard and ensure is not a problem of any 3rd party program.

  • These are the system files that I removed in the non-working O.S.:

    • Windows 10 TH2 filelist.txt

      But remember that in a step above I mentioned that I did an entire copy from the directories of the "working" O.S. to the non-working O.S. to restore the missing files to try determine if a missing file was the cause of the context-menu problem...

  • This is the WinToolkit's configuration profile that I used to generate a Windows 10 TH2 ISO (that causes the MISSING context-menu by default):

    • Windows 10 TH2 Lite.ini
  • In the "working" O.S., with WIM Registry Tweak Tool pointing to "C:\" root I started to remove all the packages using DISM that I removed in the non-working O.S. with the intention to try determine, at least, if the missing context-menu was caused by a missing package, which could be one of these:

    ...but I was unable to reproduce the issue of the missing context-menu in this way in the "working" O.S., because after I'd removed all the packages above (and restarted the O.S. when requested by DISM), the context-menu still be shown in the "working" O.S..

  • In the "working" O.S. I also started to disable all the features that I disabled in the non-working O.S. with the intention to try determine, at least, if the missing context-menu was caused by a disabled feature (very improbable, I know, because features are safe to disable by the user), which could be one of these:

    DirectPlay
    FaxServicesClientPackage
    IIS-ApplicationDevelopment
    IIS-CommonHttpFeatures
    IIS-HealthAndDiagnostics
    IIS-HostableWebCore
    IIS-HttpCompressionDynamic

    ...but again (and as expected) I was unable to reproduce the issue of the missing context-menu in this way in the "working" O.S., because after I'd disabled all the features above, the context-menu still be shown in the "working" O.S..


Solution 1:

Try in Control Panel -> Appearance and Personalization ->Personalization, to apply a default theme.

[EDIT]

Since this did not work out, here are more things to try :

  1. sfc /scannow to see if something is broken
  2. A new user profile
  3. Booting in Safe mode
  4. In the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, check NoTrayContextMenu, which should be undefined or zero.

Question: Have you set "Activate a window by hovering over it with the mouse"?

Solution 2:

Here is an article you should check.

Summed up:

No Shortcut Menu Is Displayed When You Right-Click the Taskbar

To resolve this problem, use the following steps: Click Start, point to Settings, point to Control Panel, and then click Taskbar and Start Menu.

NOTE: If the Taskbar and Start Menu icon is not present, open Control Panel and click the view all Control Panel options link on the left-hand side of the Control Panel dialog box.

On the Advanced tab, in the Start menu and Taskbar area, scroll down the list until you see the Taskbar heading.

Click to select the Display shortcut menu on right-click check box, click Apply, and then click OK.

Solution 3:

I found the problem.

The problem that caused the missing contextmenu is because the registry key HKEY_CURRENT_USER\SOFTWARE\Classes\Extensions\ContractId\Windows.Launch was deleted.

I manually deleted that key due to customization methodologies about Mozilla Firefox's protocols and DDE, in other versions of Windows I did the same without problem, but in Windows 10 if that key is deleted the taskbar's contextmenu dissapear.

I tested it various times, including in a fresh install of Windows 10 TH2 to ensure the problem is really that, and yes it is, to reproduce the missing contextmenu just delete that key (the entire key including subkeys) and then reset the system, after reset the user will not be able to show the contextmenu when doing right-click on any taskbar icon.

This is a backup from a clean Windows 10 TH2 install of all the registry keys involved in the Mozilla firefox "trick" if someone more needed to restore them:

However, for strange it can seems, after deleted those registry keys and reseted the PC, seems that a restoration of those registry keys does not fix the problem, so... if deleted those keys, could be hard to recovery the contextmenu because a registry restoration will not work. (so now I know the cause of the problem, but I can't fix it, then I started customizing a new Windows 10 ISO without deleting those keys and all works good )
