OpenNT 4.5 is a compiled build of a modified variant of Windows NT Workstation 4.0, which was created by stephanos. It released on July 28, 2015, and was added to the archive in December 2021.

Description

The OS is a build of OpenNT, an open source variant created from the leaked Windows NT 4.0 source code. Though it is not a true bootleg, it is kept in the archive for its historic value.

The compiler used for this bootleg (the one used to compile the leaked source code from which this bootleg is based) was Microsoft Visual C++ 2003, which was also compiled from Windows Server 2003 source code.

Changes from Windows NT 4.0

Minor changes

  • The kernel version is now 4.50.

Notes

Remarks

  • On some versions of VirtualBox, explorer may stop responding for a long time, but then return to normal.
