About dialog

Windows 2000 build 2020 is a Beta 3 build of Windows 2000 that was originally leaked by Blackwolf onto the #mswin2k channel of EFNET in 1999 and then found on 23 June 2015.^[1]

This build was copied directly from the build server and includes the typical elements of such builds: CHKFILE.BLD file listing checksums of all compiled binaries; IDW tools; files of the Windows NT 3.51 update engine.

Changes[edit | edit source]

The startup and shutdown sounds have been changed to the ones heard in the released product.
The appearance of the progress bars in setup has been changed.

Bugs and quirks[edit | edit source]

Installation[edit | edit source]

The unmodified version of this build cannot be normally installed (via CD boot) due to a bugcheck during setup. The user can either use a DOS boot disk to partition and format the drive and then run setup from there, or replace the cdrom.sy_ file in the i386 folder on the CD with a copy from a different build.

Also, sometimes when upgrading from Windows via WINNT32.EXE, Setup asks the user to insert the installation disc during the text-mode part, despite already being inserted. This can also be a fault with the CD-ROM driver. It is recommended to select "Install a new version" instead, go to "Advanced Options..." and select "Copy all Setup files from CD-ROM to the hard disk".

WINNT32.EXE was also modified by the warez group who shared the build to display their NFO file before the actual setup application launches. (VOS.VDB is the NFO, SOC.VDC is an AVI video, and USRV.EXE is the original WINNT32.EXE)
