Windows 95 build 33

Version 3.10.2.033 appears in file  from Windows 95 build 58s, but at this point, it is unknown if this build actually ever existed. The format of the version number is similar to the one used in Windows for Workgroups 3.1. The string "Windows Version 3.20 (Cougar)" can also be found in the same file, suggesting this may be a leftover from the Cougar project (32-bit protected mode kernel). is actually  that was used during the setup stage of early Chicago builds which still featured the old Windows 3.1-like setup. It would be copied during pre-install preparations to.
