How to change the default editor for PNG files from MS Paint to paint.net in Windows 10?

I have paint.net installed in my Windows 10 Pro. When I right-click a PNG file in the Windows Explorer, I see the Edit command. However, it opens the Windows Paint app, and I'd like to change it to paint.net. Is there a way to assign paint.net as the default editor for PNG files using a system applet?

Also, as I know, this is a question of registry settings, and the following key should contain the full path to the editor:

HKEY_CLASSES_ROOT\pngfile\shell\edit\command

In my registry the (Default) value in this key is set to

"C:\Program Files\paint.net\PaintDotNet.exe" "%1"

, but the MS Paint is opened in any case.

Solution 1:

I solved my problem by myself. First I decided to find all registry values containing "mspaint.exe" to try to replace the path to MS Paint with what I need. One of the interesting keys I found was this:

HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\edit\command

Googled it, and the first search result was this article:

Tried it, and it works! We just need to change the default value of that key to the string

"C:\Program Files\paint.net\PaintDotNet.exe" "%1"
