Bugs

 * CD and DVD drives behave like local disks.
 * The folder creation bug from build 4074 is still present in this build.
 * The Windows Classic theme will not function due to a broken  file.
 * Although DWM is present and can be activated by pressing Ctrl+Shift+F9 as in Windows Server 2008 build 4066, it will black screen due to a broken DirectX installation. It can be fixed by extracting dxnt.cab from the DirectX 9.0b installer for Windows XP (9.0c may also work), manually installing each inf file found within (Right-click -> Install, answer No to any file overwrite prompts), and copying the extracted files into the System32 directory (again say No to any overwrite prompts).
 * Safe mode is broken and displays a BSOD.
 * WordPad and Outlook Express won't start due to bugs.
 * Help and Support results in an  reset.
 * Device Manager has a bug and as such, you cannot update drivers. You can install drivers by using devcon from the Windows XP DDK, and booting with the "Enable VGA Mode" option in the Advanced Options menu in startup.
