Get the free “Defaults Programs Editor” and control file extensions and their file associations in windows.It is a powerful file association utility for windows that lets you associate any program with any file type.
In windows, when you double-click a file to open it, the OS opens the file in the program that is associated with that file name extension.
However, certain programs tend to change the default program associated with a recognized file name extension without your permission. For example, the default program associated with PDF files is Acrobat Reader. However when I decided to try another PDF reader and installed it, the program altered the default file association and associated itself with PDF files. What was even worse was it did’t even try to restore the original file association, even after I deleted the program.This resulted in windows failing to open PDF files, whenever I click “Open”, as it could not find the associated program. I needed the help of “Defaults Programs Editor” to restore the association of PDF files with “Acrobat Reader”.
