I recently wanted to add a new command menu to my right click menu to have the possibility to securely delete files and directories using Sysinternals SDelete. Using the MSDN documentation and Regedit I created a new menu item in my registry with a submenu containing my SDelete command. I did this for the filetype * as well as for Directory in order to be able to delete files and directories. So far everything worked well and my new menu worked for files and folders.

However when I later wanted to open my profile using the Explorer jumplist in the taskbar, I realized that instead of opening my explorer it invoked my SDelete command on my profile (at that point in time I was glad I added a 5 second delay before the execution ;-)). Basically all Explorer jumplist entries behaved like that.

I tracked down the problem to my directory handler but still can't figure out the problem. You can reproduce the issue by saving the following code into a .reg file and execute it. Please only do so if you know how .reg files work and can manually undo the changes!

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\sysinternals]
"MUIVerb"="Testmenu"
"SubCommands"="mySubCommand"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\mySubCommand]
@="A Command that should do sth."

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\mySubCommand\command]
@="cmd /K \"echo mySubCommand has been invoked\""

Can anybody tell me what I am doing wrong and how I can avoid this jumplist behavior?

This certainly is a bug in Windows 10, and I've see a couple of cases before. The workaround is to implement the verbs in Folder or AllFilesystemobjects, rather than under "Directory". See my response at Microsoft forums for the same issue.

  • Your response not only solved my problem, but also contains a better solution to implementing the menu - thank you! – Fabian Mar 27 '16 at 23:15
