Paint

Paint (or Paintbrush in Windows 3.x and Windows NT 3.x) is a simple graphics editor included with Microsoft Windows.

History
Paint was introduced in Windows 1.0 Beta as. At the time, it only supported monochrome graphics with a custom MSP format. In Windows 2.x, the MSP format was modified, which required any pictures made in earlier versions of Paint to be converted using the  tool.

For Windows 3.0, Microsoft decided to license Z-Soft's PC Paintbrush product, which supported true color graphics as opposed to the existing Paint tool, as a base for its Paintbrush. This version introduced support for the BMP format. With the release of Windows NT 3.1, Paintbrush was also ported to Win32.

In Windows 95, Paintbrush received a redesign and was renamed to Paint. This version was also included with Windows NT 4.0. In Windows XP, images in BMP, JPEG, GIF, TIFF and PNG formats were supported.

In Windows 7, Paint got a major overhaul. A new Ribbon user interface was introduced and a few realistic brushes were also added.

In Windows 10 Creators Update builds 14971 and 14986, Paint was briefly removed from the base Windows install and replaced with the Paint 3D application, however, it was still possible to download the old Paint from the Store. After receiving complaints about the user interface and missing features, it was decided to keep the old Paint in the base install.
