Windows 2000 build 2020

Windows 2000 build 2020 is a beta 3 build of Windows 2000 that was originally found on 23 June 2015.

Changes

 * 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.

Installation
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 can replace  file in the i386 folder on the CD with the one from a different build.

Also, sometimes when or upgrading from Windows via, 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".
