Changes[edit | edit source]

User interface[edit | edit source]

Redpill-specific changes[edit | edit source]

The Other Programs page has been replaced with a new Applications list, which displays the user's installed applications. The Charms bar now brings up a dedicated clock, and the Settings charm was redesigned to include new (albeit non-functional) option buttons for power, keyboard layout settings, and active network connections. The ability to modify the Start screen's accent color has been implemented, although its functionality is only available through the use of a registry hack and is largely limited to only two specific color choices. To change the start screen's accent color to dark blue, merge the following entry into the current user's registry hive:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Accent]
"ColorSet"=dword:00000001

Miscellaneous[edit | edit source]

Bugs and quirks[edit | edit source]

Advanced Vector Extensions CPU bug[edit | edit source]

The x86 compile of this build will not boot on some CPUs with the Advanced Vector Extensions (AVX) instruction set due to a bug where a CPU triple fault occurs immediately after the boot screen is first displayed. A workaround is discussed later in the article.

Networking[edit | edit source]

Enabling the network adapter may result in a 0x133 bugcheck on some computers.

Aero[edit | edit source]

In the x64 compile, only the top portion of the window frame is blurred when using the Windows Aero theme, leaving the side borders transparent. This is the last build to contain this bug.

Compiler[edit | edit source]

These instructions are not required for the x64 compile, and as such the compile can work without following these workarounds.

Compatibility[edit | edit source]

VMware Workstation[edit | edit source]

The Intel SSE bug can be worked around by setting the compatibility level to version 7.x or lower and the following block of code must be added to the VMX (virtual machine configuration) file in order to allow this build to boot on modern Intel CPUs:

cpuid.0.ebx = "0110:1000:0111:0100:0111:0101:0100:0001"
cpuid.0.ecx = "0100:0100:0100:1101:0100:0001:0110:0011"
cpuid.0.edx = "0110:1001:0111:0100:0110:1110:0110:0101"
cpuid.1.eax = "0000:0000:0000:0001:0000:0110:0111:0001"

The above configuration is mostly not required if the host machine has an AMD processor, and as such only requires the compatibility version to be changed.
