Windows 3.0 build 48

Windows 3.0 build 48 is an unconfirmed build of Windows 3.0. A YouTube video claiming to show this build was posted by user MicroVideos on 7 June 2020. Aside from the version numbers and copyright dates of various programs, this build appears identical to build 55.

If it is real, it would likely be the undated 1989 build, as it has an identical visual style and the version of Calculator matches the one in the [[Media:Win3.00.13.jpg|picture]]. MicroVideos, the publisher of the video, has neither leaked the build nor responded to requests for it, putting the legitimacy of this build into question.
