Windows 10 Replace Default User Account Avatar.
This procedure is not to change the user account picture, which is a different thing. The instructions below is to change the Default avatar used for new user accounts and existing accounts which don’t have a customized profile picture configured.
- Launch File Explorer and browse the following folder C:\ProgramData\Microsoft\User Account Pictures
- Change the extension of these files from *.PNG to *.OLD
Once you select the preferred image to be used as the default user avatar, resize them accordingly (see below for dimensions) and name them userava.png, userava-32.png, userava-40.png, userava-48.png, and userava-192.png. Place the files in the folder.
- userava-32.png (32×32 pixels)
- userava-40.png (40×40)
- userava-48.png (48×48)
- userava-192.png (192×192)
Restart Windows 10. The new avatar will be applied to all user accounts which use the default picture.
NOTE: The new avatar won’t be applied to accounts which have a custom user avatar/image.
