'''Microsoft Plus! 95 build 50''' is an early build of Microsoft Plus! 95. It is the earliest Plus! beta build to be shared, and it contains an early version of Space Cadet Pinball (codenamed Maelstrom), Internet Explorer 1, and DriveSpace, alongside new desktop themes.

Installation
This build is incomplete and thus cannot be installed by default. Using the setup files from 4.40.106, this build can be installed. It is recommended to install it on the Windows 95 April Test Release betas (builds 456-462; it will not install on builds earlier than 456), since running it on later versions will likely lead to errors and system crashes.

To install this build, copy the contents of the 4.40.50 installation media onto 4.40.106's and then run setup normally. There is a guide that can help on installing this software.
