Windows 2000 build 1575

Build 1575 is a pre-beta build of Windows 2000. This build has been leaked on BetaArchive on 2017-12-13 only in Workstation SKU.

New Features

 * Explorer has been updated to use an internet interface, although it is slightly buggy and have trailing effects when anything is dragged over it.
 * The "Show Desktop" icon on the taskbar has been removed.
 * Channels has been added to the taskbar which opens and Active Desktop browser.
 * The active desktop background has been removed but the Active Channels banner stays, although it is nonfunctional.
 * Like build 1515, most NT 4.0 references have been replaced with NT 5.0. However, many parts of the interface are still very similar to NT 4.0.

Bugs

 * This build cannot be upgraded from Windows NT 4.0. If upgraded, during the TXT setup it will request for the Windows NT 4.0 CD, and then when the Windows NT 4.0 CD is inserted, the setup instantly crashes with IRQL_NOT_LESS_OR_EQUAL.
 * The OS Loader has a bug during setup that it tries to load NTLDR, but since $LDR$ installs instead, it will be stuck on the OS Loader. Editing the boot sector file to boot from $LDR$ will allow setup to continue.
