Windows 98 build 1400

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

Windows Setup
Setup's sidebar color is now a darker shade of gray than the previous build. Sidebar now also shows several explanations of the setup stage the user's in (those explanations were under construction at the time this build was compiled). There's also an "Enale Sound" option at the bottom of the sidebar, however this feature is not integrated yet and it will not make its way into RTM.

The second stage of the setup now uses the same layout used in the first stage as well, however with different setup wallpaper and font for the "Memphis Setup" text.

Show Desktop
This build has a show desktop button at the end of the taskbar. This feature was removed by 1423. This feature remained absent for eleven years, until Windows 7 build 6568 reintroduced it, with the same functions as this build's button along with a new feature called Aero Peek. The Windows 7 incarnation is still present today (although Aero Peek is disabled by default).

Other changes

 * The boot screen label was changed from Developer's Release to Beta 1 and the background color was changed from white to black
 * Internet Explorer integration is also new in this build, changing some core UI functionality.
 * is labeled as "About Internet Explorer", rather than "About Windows".
 * The Start menu banner text has been replaced, now reading "IE4 Preview Release". This has been replaced in the next builds with either "Memphis" or "Memphis Beta 1", but has been readded in build 1532.
 * Paint is now capable of utilizing three colors at once when holding the Ctrl key.
 * There is now a native button to choose a second color for title bar gradients in Display Properties. Much like build 1387, the button is only displayed if one of the title bar attributes is selected.

ACPI
ACPI support is in very early development and crashes easily. Turn off ACPI or setup can crash during hardware setup with a red screen of death (used in early builds for ACPI errors).
