Setup[edit | edit source]

Setup is mostly similar to the earlier compilation of this build.

Bugs[edit | edit source]

Desktop Composition Engine[edit | edit source]

For all its instabilities, although this build's Desktop Composition Engine can show the Aero borders, it tends to be extremely buggy easily after a while.

Installation[edit | edit source]

  • Some copies of this build's installation media cannot be booted normally due to a call to a non-existent index in the INSTALL.WIM by SETUPLDR.BIN. To install this build in this case, either upgrade from a previous build or use a WinPE from a previous build.
  • On some installs, once copying files has completed, setup will fail to create a boot.ini file. Although booting will still be possible, NTLDR will default to C:\WINDOWS.

Safe Mode[edit | edit source]

Safe Mode does not log you on due to the login process change in build 4032, as it will result in There are no more endpoints available from the endpoint mapper. This was later fixed in Windows Longhorn build 4042 (main).
