This VBScript illustrates how to reset file association for a .doc file (It can be used for other file types as well with slight modification)
If we double click on a text file, it opens with Notepad by default whereas the desire application to open .txt would be Notepad++. For this we need to manually reset file association with a right click and selecting the option “Open with”. How about changing other file types (.cs, .cpp and so on) to be associated with Notepad++? This needs changing the file association for each and every file type which is not time efficient. We can use this VBScript to change file association for multiple file types.
