I've noticed that the "Open with" option is no longer displayed in the context menu (right-clicking on a file). It won't appear even if I press Shift + Right-click. How to restore this option?
- Click on Start > Run.
- Type "regedit" and press Enter, to open the registry.
- Go to HKEY_CLASSES_ROOT\Unknown\shell\openas\command
- Set the value of this key to "C:\%Windir%\rundll32.exe shell32.dll,OpenAs_RunDLL %1".
- Save your settings and close the registry.
