This is an issue that has been giving me fits all through Windows 10's lifetime. I finally stumbled upon this fix, which works beautifully. Prior, the only way I could remedy the situation was to restart explorer.exe Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ImmersiveShell\Launcher] "UseExperience"=dword:00000000
