Windows 98 build 1351

Windows 98 build 1351 is a Developer Release build of Windows 98. It is also the earliest confirmed and leaked build of Windows 98. It was originally leaked on 31 December 1996 by warez scene group GLoW, who described it as "the December release", and that "it wasn't Beta 1 because IE 4 wasn't ready". It was included on the warez CD "Dragon 5" who claimed that "people say it's 75% faster than Windows 95" and the warez CD author "thinks it's much faster".

The setup routine has been revamped in this build, making it resemble the 98/ME setup routine in layout, if not in overall look and feel. It also installs Microsoft Plus! themes and components by default.

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).

BSoD during Windows Help configuration
Sometimes setup also crashes with a blue screen of death when configuring Windows Help. Should this occur, the user will need to retry the installation again.
