Steps to reproduce

Install PowerShell Core 6.1 on Windows choosing to add context menu "Open PowerShell from here". Once installed, just clicking any Windows shortcut for a folder opens a PowerShell 6.1 window not the Windows Explorer window at the folder.
This only seems to happen with Directory\Folder shortcuts in Quick Launch (%APPDATA%\Microsoft\Internet Explorer\Quick Launch) that are then exposed on Quick Launch toolbar on W10 taskbar as they respond to single click to open. The single click open PowerShell. Uninstall returns behavior to normal.

Expected behavior

Clicking a folder shortcut opens the folder in Windows Explorer.

Actual behavior
---------------

Clicking any Windows shortcut when on Quick Launch toolbar on W10 taskbar for a folder opens a PowerShell 6.1 window not the folder in a Windows Explorer window at the folder.
