I pinned two network locations to my quick access in windows 10. One is no longer accessible, and I would like to remove it, but the context menu only lists "Expand." Is there a registry key or something I can remove?
Click Quick Access. In the right-pane, select the network location, press and hold the CTRL key (for multi-select) to select another Pinned folder from local drive. Right-click menu should now show Unpin from Quick Access. Both will be removed though. (Source: http://www.winhelponline.com/blog/unpin-ftp-links-stuck-quick-access-windows-10/)
