Windows 95 build 40

Windows 95 build 40 is a supposed early build of Windows 95. Former BetaArchive member KenOath posted several screenshots, but their authenticity remains disputed by some due to several inconsistencies within them.

Fake build
There was also a fake copy floating around a while ago, but it is unrelated to KenOath. It was made with files from various builds (mostly build 58s), supposedly even from the real build 40, but this was never proven to be true. It remains available online to this day. There are in fact two files ( and  ) in build 58s with version number 4.00.40, but this does not necessarily mean they come from build 40.

Confirmed build
There may be a confirmed copy that YouTube user akibachudoku has in a video covering this build, but it is still unknown if the copy was real.
