MS Paint has very little options for editing images and set as Windows default image editor.Whenever you click on “EDIT” in the context menu on right clicking an image, MS Paint is opened.

Here’s a simple registry trick to change the default image editor in Windows to your own choice.

• Click Start, Run and type regedit.exe
• Navigate to the following branch:

HKEY_CLASSES_ROOT\ SystemFileAssociations \ image \ shell \ edit \ command

• In the right-pane, double-click (default) and set its data as

“C:\Program Files\Paint.NET\PaintDotNet.exe” “%1″

• Close regedit.exe

Note : Be Careful while trying to edit the registry, doing wrong can cause damages to your system.

After the registry change when you click on Edit in the context menu, you favorite editor is launched for editing the image.
