Windows Longhorn build 4088

Windows "Longhorn" build 4088 is a Milestone 7 build of the Microsoft Windows Longhorn operating system. Previously, only the Preinstallation Environment for this build had leaked. BetaArchive member Daniel has since uploaded the full version of this build to BetaArchive FTP on 2015-01-13.

Being near one of the final Longhorn builds, this build tends to take a long time to install and can be unstable. WordPad interface has been fixed.

Bugs

 * Safe mode is completely broken, it displays a BSOD.
 * CD and DVD drives appear and behave like local drives.
 * When enabling the slideshow sidebar tile,  restarts in a loop. Only fix is to remove the slideshow tile from the registry.
 * Help and Support causes an  restart.
 * Computer Management displays script errors.
 * The Windows Classic theme will not function due to a broken  file.

Installation
The  part for setup tends to hang while trying to launch, you can try to open Task Manager on the second Command Prompt window by running   and then terminating   to get the hardware setup to load.
