Windows NT 3.51 build 854

Windows NT 3.5 build 854.1 is either a post-RTM build of Windows NT 3.5 or a very early build of Windows NT 3.51. It was originally scene leaked by several warez groups and has been widely available online for years.

Compared to Windows NT 3.5 RTM build 807.1, it includes an early version of Chicago Shell and User update (commonly known as "NewShell"), MSGINA, new Media Player application, CMD customization, new Windows 95-like common UI controls (e.g. tooltips on buttons), support for NTFS compression and the PCMCIA interface, as well as the OFS driver (version 0.33). All of these features except NewShell and OFS were later introduced with Windows NT 3.51.

Chicago Shell
To install Chicago Shell, follow this procedure:
 * 1) Copy the IDW, MSTOOLS, and UI directories from the GUI or NEWSHELL folder of the installation media onto the Windows root directory of the hard drive.
 * 2) Edit the  file and add on the "path" switch in the file to include.
 * 3) Run the  file from the UI directory and reboot the computer.
 * 4) *If you get a STOP error on reboot, then the NewShell doesn't work for your PC, use a different computer.

OFS
Support for this file system can be enabled using The Distractor's batch file.
