Changes[edit | edit source]
Setup[edit | edit source]
setupclient.exe has been majorly revamped and is now named
setup.exe, replacing the legacy setup launcher. The progress bar at the top has been moved more towards the center and the steps have been rewritten. The legacy setup is still accessible by launching
setup.exe in the
System crash[edit | edit source]
The blue screen of death has been redesigned in this build, dropping the design seen in Windows XP in favor of a simplified black screen informing the user that their computer requires a restart, along with the bugcode (minus the parameters). This bugcheck screen utilizes the Segoe UI font, leveraging the VBE functionality that was implemented in earlier builds and the BGFX subsystem. However, in the event that the system crashes early in boot before BGFX is initialized, a fallback is used which merely dumps the bugcode parameters along with a short message prompting the user to hold down the power button.
Default user account picture[edit | edit source]
The default user account picture has been updated to that used in Windows Live Messenger.

Starting with this build, it is possible to remove the Start button from the taskbar. To accomplish this, a new DWORD value in
YouBettaHideYoPearl is required to be made, with its value set to 1. After doing so, log off and log back in. If done correctly, the Start button should be removed.
UEFI[edit | edit source]
Support for UEFI GOP (Graphics Output Protocol), used for producing a graphics output on devices with UEFI Class 3, has been added.
Redpill[edit | edit source]
Many changes have occurred since build 7880. Accents and backgrounds have been implemented, accessible using a registry key. The Start screen now has multiple views - while this is hinted at in 7880 by the existence of a "Move to Other View" option found while right-clicking on the Start screen tiles, it is unimplemented. This other view is an "Other Programs" view containing all installed programs. As a result of this, there are far less applications in the default Start screen view. Animations have been implemented. Tile colors have been changed to be more uniform.
A user tile is now located at the top of the screen filled with the user's profile picture (replacing the Search button, which was not seen again on the Start screen until Windows 8.1 Update 1 in 2014), as well as a volume icon. To replace the Metro Horizon (removed, although not entirely so, in build 7878), a Desktop tile has been introduced. Clicking it brings the user back to the classic Windows desktop.
There have also been an immense amount of changes outside of the Start screen. An ImmersiveSettings app has been introduced, the ancestor of PC Settings, and several apps have been redesigned to fully use WinRT. Auto Colorization is no longer enabled by default on the Aero theme. ImmersiveBrowser, or IE Metro mode, has also been implemented. Advanced Task Manager, a more advanced version of Task Manager, has been implemented as well. The Metro OOBE also had a major overhaul. The Metro downspace has been dropped in favor of the snap function.
Start screen accent[edit | edit source]
To get the Start screen accent, open Registry Editor, head to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\, create a new key called DWM, make a DWORD called
EnableAccent and set its value to
1. Afterwards, log off and then log back on again.
As this build's implementation of the accent is incomplete, visual artifacts may appear across the screen.
Removable media prompt[edit | edit source]
The removable media prompt has been revamped as well, using the new Metro design. It mostly consists of the same actions as the previous removable media prompt used in earlier builds of Windows 7.
Login[edit | edit source]
The login screen was updated and pattern login now works. However, to set a pattern, a password must be created, otherwise it fails to create due to the patterns not matching. Removing the password will still keep pattern login, but choosing the password option instead will instantly log in to the user's account, due to the password being removed. Additionally, when re-logging in, it will keep using the password option and therefore, instantly log in to the user's account.
A lock screen has also been implemented as well and will appear after the computer is set to require Ctrl+Alt+Del to be pressed to log on.
