Windows 98 build 1400

Windows 98 build 1400 is a Beta 1 build of Windows 98.

Features

 * It includes several updates to Windows Setup.
 * This build has a show desktop button at the end of the taskbar. This feature was removed by 1423. This feature remained absent for 11 years, until Windows 7 build 6568 reintroduced it, with the same functions as 1400's button along with a new feature called Aero Peek. The Windows 7 reincarnation is still present today (although Aero Peek is disabled by default).
 * An "Enable Sound" checkbox is included, however, the functionality is not yet in place.
 * The sidebar layout is now used in the second stage of installation, and Setup now performs the final stage of configuration without a reboot.
 * Internet Explorer integration is also new in this build, changing some core UI functionality.
 * WINVER is labeled as "About Internet Explorer", rather than "About Windows".
 * The Start Menu banner text has been replaced, now reading "IE4 Preview Release".

ACPI
This build has buggy ACPI support, thus it will usually crash in the second stage of setup with a red screen of death (see below). To fix this, disable ACPI in the VM or machine.
