Microsoft is working in the latest builds in to update different elements of the system for greater coherence with the design of Windows 11. In the build 22538 Besides of new task manager, we find a novelty in the default profile picture in user accounts.
Windows 11 gets a new default profile photo based on Fluent Design
Microsoft has updated the default profile picture without no kind of notice on the latest Insider program build. This photo appears when the user does not have any image set to your local account or Microsoft account. Although I know redesigned the login screen, they did not update the profile picture which was still the same that used Windows 10.
But now and thanks to the Twitter user Kristian Kenny that informs us of this change, we can know that finally Microsoft has updated that little detail for an older coherence with the current lines from design of Windows 11. A change that has been a bit unnoticed by the community at large. This new profile picture is not a great novelty since it is already used in multiple products from Microsoft.
