Windows 95/4.00.122

Windows 95 build 122 is the earliest leaked Beta 1 build and also the last leaked build to call itself "Microsoft Chicago". Build 180, the next leaked build, is already branded as "Windows 95". It is available on the FTP, though a checked version of this build also exists.

By this point, the new Explorer user interface was pretty much complete and mostly resembles the final product, later builds only added various cosmetic changes to it. The release notes are available at /RELNOTES.rtf/.

Boot issues
This build can be rather difficult to install for many as it likes to hang at the bootscreen, so member KenOath also provided a pre-installed VHD of this build.

Build "177"
Build 122 is often mislabelled as build 177, probably after 117, another mislabel of 122, was mislabelled again. The copy of build 180 that Overdoze leaked to OSBA was also mislabelled as build 177. It was supposedly scene leaked back in the day and is even listed in several warez CD lists (e.g. Crack 2), but hasn't been found yet.
