Add Open With To All Files

Registry Tricks

Add Open With to all files:

 You can add "Open With..." to the Right click context menu of all files.
 This is great for when you have several programs you want to open the same 
 file types with. I use three different text editors so I added it to the 
 ".txt" key.
 
 1. Open RegEdit
 2. Go to HKEY_CLASSES_ROOT\*\Shell
 3. Add a new Key named "OpenWith" by right clicking the "Shell" Key and 
 selecting new
 4. Set the (Default) to "Op&en With..."
 5. Add a new Key named "Command" by right clicking the "OpenWith" Key and 
 selecting new
 6. Set the (Default) to "C:\Windows\rundll32.exe shell32.dll,OpenAs_RunDLL %1", 
 C:\ being your Windows drive. You must enter the "OpenAs_RunDLL %1" exactly 
 this way.
