As you can see in the first image, I have selected always open with notepad++ program. But, the problem is that the all the php files are opening with notepad++ program but the icons doesn't change. The php script file takes the previous program icon i.e. Dreamweaver, which I previously used for opening my php script files.
This happens with other file types also i.e. audio or video file types.
I want to know- how can I resolve this problem.
My system OS - Win XP sp3; Antivirus - KIS 2012; and also malwarebytes 1.62.
