When you click the File Explorer shortcut in the Taskbar or launch Explorer using WinKey + E hotkey, error “Windows cannot find “”. Make sure you typed the name correctly” may occur.
This happens if you’ve disabled the Quick access feature using registry edit, and File Explorer is set to open in Quick access view (default setting). To fix the problem, you may either enable Quick access back, or set File Explorer to open This PC view by default, via Control Panel > Folder Options.
