Windows 8 build 8045 is a build of Windows 8, which was uploaded to BetaArchive on 26 January 2020.

New features and changes[edit | edit source]

  • The system crash screen has been redesigned to resemble the one found in the RTM build, albeit with a black background instead of a cerulean shade.
  • The background in the wordoku puzzle desktop wallpaper has been changed to feature a set of colorful strands at the bottom of the image.

Recovery[edit | edit source]

  • The Refresh your PC option was added under the name Rejuvenate your PC.
  • When booting into Startup Repair, the spinner now reads "Preparing Automatic Repair."
  • This build introduces an early version of the "Recovery" screen.

Startup[edit | edit source]

  • The loading animation has become larger and whiter on some occasions.
  • The boot screen has been updated to feature a smaller loading spinner.
  • The boot manager entry is now named "Windows Developer Preview" as opposed to "Windows 8".

Redpill[edit | edit source]

The Aero theme was updated, and now features more distinct close, minimize and maximize buttons. The right-hand charms bar is now accessible again without the need for a touchscreen. It is accessible by pressing the ⊞ Win+⇧ Shift+C key combination. The close button has been removed from the search charm. MSHelp was also renamed back to Windows Store. However, it is still not functional, and opening it results in a black screen.

Setup[edit | edit source]

  • Setup graphics have been updated to remove Windows 7 references.
  • The splash screen now shows a colored Windows logo instead of a white one. Additionally, a gradient has been introduced to the background, as opposed to it being single colored and the color has been changed from teal to blue.
  • Descriptions are now more informal.
  • The progress bar located at the top has been removed, but the stages can still be seen.

Verbose boot removal[edit | edit source]

Starting from this build, the option to enable verbose boot by appending the /sos boot argument or enabling OS Boot Information in the System Configuration utility is no longer available. If verbose boot is enabled, it will just show the build's regular boot screen. Additionally, this also means the Safe mode now uses the regular Windows boot screen as well.

Bugs and quirks[edit | edit source]

  • The Start screen appears to hide all tiles on boot unless they are interacted with.
  • The lock screen may not display correctly if the Start button was removed via the YouBettaHideYoPearl registry value.
  • The leak warning in winver is colored black instead of the red that is seen in most builds.
  • Using the scroll wheel in the mouse in the Immersive Control Panel may lead to the area where the user is scrolling becoming white. Use the scrollbar in the Immersive Control Panel to prevent this bug from happening.
  • The Windows 7 OOBE background is glitched.
  • winver loses the "Copyright" word in the Copyright section.

Compatibility[edit | edit source]

To install or run this build in VMware Workstation, the hardware compatibility version must be set to versions 8.x/9.x; otherwise, a bugcheck will occur.
