Windows 8 build 8128

Windows 8 build 8128 is a post-Developer Preview build of Windows 8, which was uploaded to BetaArchive on 4 January 2019.

Integration of Redpill
This build is notable for being the first available build not to use Redpill, thus all the Metro features (such as the start screen, the Metro login screen, and Immersive app execution) are now available out of the box, compared to previous builds which required the use of a Redpill utility (or, in the case of 8102, be distributed with Redpill already applied) to use the features.

As such,  was removed, with its functions being integrated into other files, such as. Also, any registry entries for Redpill (most notably, which was commonly used to disable Redpill in 8102, restoring the old Windows 7 shell) no longer function.

Also, with the removal of Redpill making it irrelevant, the Windows 7 shell and its associated components, such as the start menu, were removed, leaving their Metro counterparts as the only ones available.

Placeholder Sound
This is the first build to have the  sound. However, it is a placeholder and obviously recorded by an amateur, most probably a Microsoft employee. While it does not have a date of creation in its metadata, it does have a date of September 29th, 2011, a week prior to this build's compilation, so it was likely a recent addition.

Windows Error Reporter
will encounter an exception loop; closing the message that the program was terminated will result in it coming back shortly.

Hyper-V launch failure message
If VMX is not present or enabled in the BIOS options, the boot screen will display a  message.
