Windows Vista/6.0.5048.winmain idx02.050401-0536

From BetaArchive Wiki

Windows Longhorn (Vista) build 5048 is the first leaked build of the Omega-13 reset builds. It is the last build branded as Longhorn (leaked). This build has full aero and has great effects. There is no sidebar in this build. The build does have a 50 file limit per folder that cannot be removed.

A 64-bit version is also avaliable.

Sound drivers are very difficult to install on this build, but it is possible to get them to work.

TweakNT

Most builds after the Omega-13 reset cannot use TweakNT, which removes the timebomb. However, TweakNT is known to successfully remove the timebomb on some early Omega-13 builds, including 5048.
