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 login screen was updated and pattern login now works. The Metro downspace has been dropped in favor of the snap function.

The blue screen of death has been redesigned in this build, dropping the design seen since Windows XP in favor of a much simpler black screen that simply lets the user know that the computer needs to restart along with the bug check code (minus the parameters). This bug check screen uses Segoe UI font, leveraging VBE support that was implemented in earlier builds and the BGFX subsystem. However, in the event that the system crashes early in boot before BGFX gets to initialize, a fallback screen is used which merely dumps the bugcheck codes along with a short message to reboot the computer.

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.

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.

Immersive apps[edit | edit source]

  • Immersive Browser: C:\Program Files\Microsoft\Immersive Browser\Microsoft.ImmersiveBrowser\miexplore.exe.
  • Immersive Reader: C:\Windows\System32\glcnd.exe.
  • Metro Control Panel: C:\Windows\System32\SystemSettings.exe.
  • Webcam Application: C:\Windows\System32\webcam.exe.

Bugs and quirks[edit | edit source]

Setup[edit | edit source]

The messages shown while the Setup is starting or restarting the computer are cut off.

Arial[edit | edit source]

This build uses the Arial font for the title bar and watermark because of a typo in the aero.msstyles and aerolite.msstyles files.

Start screen[edit | edit source]

  • Due to issues with the Start screen's accent, there will be rendering issues when using EnableAccent.
  • The Start screen may be unresponsive for a minute after login.

Explorer crashes in Safe Mode[edit | edit source]

When booting into safe mode, Explorer may crash after logging in.

Login sound[edit | edit source]

Upon logging in, the login sound will play three times instead of once.

Aero Glass on the Home Basic SKU[edit | edit source]

The Home Basic SKU doesn't support Aero Glass borders by default, but it can be enabled, like in build 7880, by clicking on "Windows 7 Standard" color scheme in Window Color and Appearance dialog from the Display control panel item.

Upgrading[edit | edit source]

To start the upgrade process, you must use setup.exe in the sources folder, or else setup will say that a problem occurred.
