The writing’s on the wall: Microsoft has targeted the venerable Microsoft Paint app for extinction within Windows 10. In the Windows 10 Fall Creators Update due next month, Microsoft has classified Paint as “deprecated,” meaning that the app’s not in active development and might be removed in future releases.
Deprecation doesn't necessarily mean certain death. Microsoft deprecated the Edge browser’s Reading List with the Creators Update, yet that feature remains within the Insider version 16193 of the Fall Creators Update. But if Paint's deprecated it won't improve, which means the simple march of time could render it obsolete. On the other hand, the same support document formally removes the 3D Builder app and Outlook Express, which means they're just plain gone.
