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



In Windows, the default application used to open and edit .PNG files is Microsoft Paint. However, the Paint software does not have all the features or capabilities that an image editor such as Paint.NET may offer. As an IT administrator, you may want to change the default application used to open and edit .PNG files from Microsoft Paint to Paint.NET for all users in your network.

Changing the default application for .PNG files from Microsoft Paint to Paint.NET can be done by making changes to the registry of the computer. It is recommended to make a backup of the registry before making any changes.

To change the default application for .PNG files from Microsoft Paint to Paint.NET, open the Windows Registry Editor. To do this, press the Windows logo key + R, type regedit, and then select OK.

In the Registry Editor, navigate to the following folder:

HKEY_CURRENT_USER\\Software\\Classes\\PNGFile\\shell\\open\\command

Right-click the command folder and select Modify. In the Edit String window that appears, replace the existing command with the location of the Paint.NET executable file. The default location of the Paint.NET executable file is usually at “C:\\Program Files\\paint.net\\PaintDotNet.exe”.

Click OK to save the changes. The changes will take effect immediately. All users will now have Paint.NET as the default application when opening .PNG files.

To verify the changes, right-click a .PNG file and select Open With. The Paint.NET application should be listed as the default application.

Changing the default application for .PNG files from Microsoft Paint to Paint.NET is a simple process that can be done quickly and easily. However, it is important to remember to make a backup of the registry before making any changes. This will ensure that if any changes are made in error, they can be reverted quickly and easily.
