Feature Focus: How to disable the “Windows cannot open this file” dialog box

If you’ve ever clicked on some file in Windows and seen this dialog box, you know what I’m talking about:

unknown-file-dialog

The web service is completely useless, and most of the time you already know what program you want to use to open the file. Luckily, it is easy to disable this dialog box with Default Programs Editor (download). Simply launch the program, and click on the Options button:

options-button

Options button

Then, click the button that says

Disable 'Search web for unknown extension' Dialog Box
Disable 'Search web for unknown extension' Dialog Box

Disable 'Search web for unknown extension' Dialog Box

And that’s it!

Now, when you try to open a file with an unknown extension, Windows will skip the unknown extension dialog and display the “Open With…” window to choose a program.
