How to associate a file extension to a program without making it the default program

Question

I\'m deploying a small conversion tool on some systems, and want the users to be able to run it from the right click Open with menu. But I don\'t want to change

Answer 1

You can add scripts to the context menu (below Open with) by adding it in the windows registry:

1. Open regedit
2. Goto HKEY_CLASSES_ROOT\your_class\Shell
3. Add a new key and give it a name
4. Edit the (Default) value of this key and insert the text you want to show in the context menu
5. Add a new key named Command under your newly created key
6. Edit the (Default) value of this key and insert the command you want to execute
7. Enjoy!
