I just realized, that recent Windows version make it very hard to customize some aspects of your desktop.
As I am using Sumatra PDF as my default PDF viewer, I do not have the typical Adobe icon on my desktop. While having these icons on my Mac as well as on my work PC, this is rather confusing.
I came along File Types Manager which actually takes away the registry fiddling.
It works with Windows XP, 7/8 and Windows 10. if you have any .ico files available it is pretty easy to change an icon for a particular file type just by assigning it.
Also there are tons of other features, I haven’t used yet.
If you want to change file type icons on a Windows 10 system, you ca use File Type Manager to do so easily.
