As part of the 'Windows 10 Fall Creators Update', Microsoft are planning to remove/deprecate the infamous Paint program.
Microsoft have released a list of programs that will be removed/deprecated in their Fall/Autumn update. The full list of affected programs can be seen here - https://support.microsoft.com/en-us/help/4034825/features-that-are-removed-or-deprecated-in-windows-10-fall-creators-up
But it's not all doom and gloom, as Microsoft have released a new option (although not an update to Paint), called Paint 3D. This new feature is available in the Windows 10 Creators Update.
