WIn : Right click 'Open With' Command missing

ALL file types, including non-executable files, follow this steps:

 

1. Click Start, All Programs, Accesories, Notepad.

2. Copy and paste this text:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT*shellexContextMenuHandlersOpen With] @=”{09799AFB-AD67-11d1-ABCD-00C04FC30936}”

3. Click File, Save As, name the file “OpenWith.reg” (WITH THE QUOTATION MARKS) and click OK.

4. Now double-click OpenWith.reg, click Continue, Yes, OK, and see if the problem is solved.

Note :

My personal advice is not to use ANY registry cleaner on the system.
