Windows 2000 build 1585

Windows 2000 build 1585.1 is a pre-beta build of Windows. This build has IE 4 and Outlook Express Platform Preview on by default, but they don't have the IE-style Explorer view.

It also includes an update to system's graphics. The high-color icon feature from Plus! is now part of the system, and the icons have been updated to reflect their lower-color counterparts. Other icons (folders, disks), as well as those in the Start Menu, are the ones that will be used in the final build of Windows 2000. The internet-based Windows Explorer from build 1575.1 is also present.

Installation
The CD for build 1585.1 is bootable, however, it does not work properly and crashes before setup can be launched. The easiest way to install the build is to use another DOS/Windows NT installation to run  or   from the CD. In DOS mode, this will generate 3 floppy disks which can be used to start the installation. Note that if  is damaged, it will need to be repaired before starting the installation.
