Windows Longhorn build 4084

Windows Longhorn build 4084 is a Milestone 7 build of Windows Longhorn. It looks like almost all the other 408x and 409x builds, but a lot of features are absent from this build. It was leaked in October of 2011. Microsoft realized that in its current form, Longhorn was not feasible, so many features were removed and were scheduled to be added in subsequent versions of the operating system.

This build, along with other builds bearing the 408x branch, are a result of that decision. It included a few features, running at the bare minimum working configuration. Despite that, installation takes a long time and the build tends to be unstable after installation.

Bugs
There are some bugs/issues present in this build, some of which are:
 * The Windows Classic can't open due to missing files.
 * Safe mode is broken and displays a BSOD.
