"Always use this program to open these files" is grayed out. Why?
- by Herb Caudill
I inadvertently set the Registry Editor to be the default editor for *.txt files. Now when I go to change the default, "Always use this program to open these files" is grayed out. This is the case whether I right click on the file and choose "Open with...", or start with the "Set Default Programs" control panel.
Why? How can I fix this?
