Microsoft Cairo build 1175

There are 2 versions leaked, one was leaked long time ago, and another was leaked by The Distractor from BetaArchive on 2017-03-17.

The version that was not leaked by The Distractor is just a normal NT 4.0 Build 1175, or a Shell Update Release (SUR)

The version The Distractor from BA leaked has some interesting things with it.

Cario's Object File System (OFS), changes in setup, changes in login screen, "Cairo domains", lots and lots and lots of files that mention "Cairo".

And that's just from a preliminary look.

Remember, despite the mislabels, NT 4.0 "SUR" is not NT "Cairo". (The Distractor, BetaArchive).

Installation
To install, use VMware, and set compatibility to 5.X Install and install with NTFS, or FAT. OFS will cause it to hang!
