Enhancing the "Open Command Prompt here" Context Menu experience

For decades, you've been able to hold down [Shift] and Right-Click on a folder (or the background of a folder) to get a "Open Command Prompt here" option. ("Copy as path" is also on this menu)

I recently also discovered, that you can open any program using the folder as the current folder by typing a command (e.g. cmd.exe or powershell.exe) in the Address Bar.

In the Windows 10 Creators Update, the default shell is being changed to PowerShell ("Open PowerShell here") -- in light that PowerShell is a more comprehensive shell than CMD.

Looking into how this works, I discovered and realized two things:

• Sometimes I want more than just a single shell option in the menu
  • Command Prompt
  • PowerShell
  • GIT
  • Visual Studio Developer Tools
  • etc.
• With the introduction of UAC in Windows 7, it's no longer possible to launch one of these shells/applications elevated

The first issue isn't an issue. Adding additional entries is easy -- it just requires additional "shell\<verb>\command"  registry entries.

• The order in the menu is the alpha order of the <verb>
• The menu text is the "shell\<verb>\(default)" REG_SZ text
  • i.e. the menu doesn't have to be in the alpha order of the menu text
• Add "&" in the text to specify the keyboard shortcut

The second observation - the elevation - is the issue. If the target EXE isn't manifested as requiring elevation, you need to use the special verb "runas" to cause the elevation. That's great if you're just adding one entry, but problematic if you want more than one.

What you have to do is to use the "ExtendedSubCommandsKey" concept. This creates a sub-menu. Each sub-menu can have a "runas" key, allowing multiple elevated entries in a context menu tree (one per menu/sub-menu).

The great thing about the "ExtendedSubCommandsKey" concept is that the value is a "reference". Meaning a single configuration can be shared between the folder's node ("Directory\shell\...) and the folder's background ("Directory\background\shell\...) context menu registrations. Both areas point (reference) the "Directory\ContextMenus\shell\..." area -- saving you the need to duplicate the <verb> settings.

Within each sub-menu (each ContextMenu area), you make the ...\shell\<verb>\... keys as normal. The only exception is the menu's name; it is set via a "MUIVerb" REG_SZ, rather than the usual "(Default)" REG_SZ.

In my example below, I have the Command Prompt and PowerShell supported as sub-menus. Within each sub-menu, there is a verb to launch the prompt non-elevated ("open") and elevated ("runas").

• Command Prompt support
  • HKEY_CLASSES_ROOT\Directory\shell\01MenuCmd --> Directory\ContextMenus\MenuCmd
  • HKEY_CLASSES_ROOT\Directory\background\shell\01MenuCmd --> Directory\ContextMenus\MenuCmd
  • HKEY_CLASSES_ROOT\Directory\ContextMenus\MenuCmd
    • open --> Command Prompt
    • runas --> Command Prompt Elevated
• PowerShell support
  • HKEY_CLASSES_ROOT\Directory\shell\02MenuPowerShell --> Directory\ContextMenus\MenuPowerShell
  • HKEY_CLASSES_ROOT\Directory\background\shell\02MenuPowerShell --> Directory\ContextMenus\MenuPowerShell
  • HKEY_CLASSES_ROOT\Directory\ContextMenus\MenuPowerShell
    • open --> PowerShell
    • runas --> PowerShell Elevated

What you get is something like this (this example is a right-click of a folder's node):

[caption id="attachment_515" align="alignnone" width="585"] Command Prompt menu[/caption]

[caption id="attachment_505" align="alignnone" width="542"] PowerShell menu[/caption]

You don't have to use it run an application elevated to not. For example, with GIT, it can be use to launch the GIT GUI or GIT BASH.

• GIT Prompts
  • HKEY_CLASSES_ROOT\Directory\shell\03MenuGIT --> Directory\ContextMenus\MenuGIT
  • HKEY_CLASSES_ROOT\Directory\background\shell\03MenuGIT --> Directory\ContextMenus\MenuGIT
  • HKEY_CLASSES_ROOT\Directory\ContextMenus\MenuGIT
    • git_gui --> GIT GUI
    • git_shell --> GIT BASH

[caption id="attachment_535" align="alignnone" width="407"] GIT menu[/caption]

Icons, UAC and hiding other menus

To make make things look pretty/orderly, I've set the following to add the appropriate icon, indicate UAC, and to hide (unwanted) menus.

• Set the application's icon via the "Icon" REG_SZ on the parent and child nodes
• Enable the UAC icon via the "HasLUAShield" REG_SZ on the elevated nodes
  • Note, this has no effect on whether elevation is applied or not. It's purely cosmetic.
  • If Icon is also set, it's a tiny icon in the bottom right
  • If Icon isn't set, it's a full sized icon of the shield
• Add the "Extended" REG_SZ on the (old) settings that you want to hide in the Shift Right-Click menu
  • I add these, instead of deleting the entire node because A) TrustedInstaller only has access B) Installers will put them back again
  • You'll get a error/warning when merging the registry file if they are owned by TrustedInstaller (not an issue)

ENJOY!
