Windows 95 build 40

Chicago build 40 is one of the earliest Chicago builds. Former BetaArchive member KenOath leaked screenshots of this build, however they were later proven fake, and the build itself is not leaked. A fake build 40 was made containing several files with build number 40, but it's unknown whether those files are real. PROGMAN.EXE, along with other files, in build 58s has this version number.

Although this is not the absolute earliest build of Chicago, this is among the earliest of them. KenOath released some screenshots but they are not proven to be real.
