Windows 8 build 8423

Windows 8 build 8423 is a build of Windows 8, which was uploaded to BetaArchive on 16 January 2019 only in the Croatian language for the x86 architecture. It is the last build available to include the Windows Aero visual style and the stacked 8 default wallpaper.

Installation
Turn off all network adapters even if you set the BIOS date for the machine, otherwise after the hardware setup it will automatically adjust to the current time via online time syncing and thus activate the timebomb. This requirement is optional, but not doing this will result in the computer rebooting every two hours. Another way is to install this build on the current date, it won't activate the timebomb.

Crash
In VMware, this build can sometimes crash on startup with a  bugcheck. Restarting will fix the problem.

Desktop Background after expiration
If installed after the timebomb date no image wallpapers can be used whatsoever, not even the default wallpaper, leaving you with a solid black desktop background by default.

hal.dll
Common to most leaked Windows 8 builds, this build can still boot successfully, on most hardware Windows would otherwise no longer be able to boot on, without the hal.dll file being present. This is in contrast to officially released builds of Windows 8, as well as builds of other Windows versions, which can no longer boot without the file being present, on the same hardware.
