📎 AI Summary:
The thread discusses how to reset a file extension's default program to "no program" in Windows 7. The original poster wants to remove the default association to regain no program handling the file type but hasn't been able to, and receives instructions to edit the registry to clear the default command. The overall sentiment is helpful, with a polite exchange of guidance and thanks, despite the delayed response.

Hi I know it sounds like a kinda pointless thing to do, but does anyone know how to reset default file opener to "no program" in a windows 7 computer.
And reset it back to this:
An image from 'No File Opener'. The image shows a missing or corrupted file icon on a blurred background.
little icon. I accidentally set the wrong default file opener, and I don't have any other program to open this type of file. And I want to reset it back to no program

Yes, you need to
  • look in the registry under HKEY_CLASSES_ROOT for the file extension such as .txt.
  • Select the extension key (in this example .txt) and look at the default value. In my example it says txtfile.
  • Now scroll down or search for txtfile, which will also be under HKEY_CLASSES_ROOT and expand it
  • Then expan shell and lastly open
  • select the command key underneath that
  • Blank out the (Default) value under the command key
