.txt will open open in Command Prompt

I miss the Windows XP file association manager, it allowed you to select which of the commands would be executed when you double click a file (open, print, edit, etc...), it was removed since Vista.
Some good people created the Types application, which you can use to select the default action of the file double click, all you go to do is select the "txt" extension from the list, right mouse click, hit "Properties" and on the "Actions" tab right click "open" command and assign "Default" to it.
Hopefully this will solve your problems, although I think your PC is probably infected with some kind of malware that will continuously change that setting back, so I also advise installing some anti-virus like MSE or NOD-32 and preform a full scan.
Good luck.
