Unlike later Milestone 4 builds and even build 4001, this build uses the old i386-based setup routine instead of the newer one based on the WIM installation format.
Grabberslasher first gave the details of this build on his UX.Unleaked blog. On 23 January 2020, this build was listed on a BetaArchive thread by the aforementioned user to be released to its FTP server, and was released on 31 January 2020, alongside build 4040 and build 5356. WinUnleaked also had images of this build.
This build is specific in that it was built as a private build, with binary files having the
VS_FF_PRIVATEBUILD flag set in their version information and the builder user name being present in the build tag, although the user name suggests that the build was built by the official Lab06 user account.
New features and changes[edit | edit source]

Bugs and quirks[edit | edit source]
General[edit | edit source]
WcmRegister.exewill throw out user registration errors upon login.
- If Windows Explorer is restarted while an application is still open, closing the app will still have its taskbar task shown.
- Windows may not register all available display resolutions on certain graphics hardware and driver combinations.
Installation[edit | edit source]
This build can't be installed via a CD boot because it attempts to incorrectly load the
coverage.dll file. As a result, the system will BSOD after formatting the drive due to loading this file.
setup.exe also attempts to load this file and quits due to it, but running
winnt32.exe can allow setup to load.
If this build is planned to be clean installed, the user needs to partition and format the disk with a MS-DOS or Windows 9x boot floppy disk.
During GUI setup, there will be a copy error that it fails to copy
WinFSSyM.sql, the user can safely skip copying these files.
Desktop Composition Engine[edit | edit source]
Desktop Composition Engine requires either compatible hardware or VMware Workstation 6.5.x to work (just 6.5x compatibility won't work), otherwise it will result in a black screen that can only be exited by a hard reset.
Control Panel[edit | edit source]
- Display Properties mentions the Luna theme as the Plex theme.
