Microsoft Edits You Won't Believe Real | Windows Longhorn Build 5001 

This is an extremely rare Longhorn build!

The Longhorn in the Bliss wallpaper is probably looks pretty realistic. I also noticed the Windows Brand banner changed from XP to LH. This is probably where MS is starting to replace the Windows XP references on Windows Longhorn builds However the watermark and some areas still says Windows XP.

In-fact: Longhorn Build 5001 is based on Windows Server 2003, they just removed features from Server 2003 & re-added some stuff from Windows XP (wallpapers, themes, visual styles etc...), that's why you will see Server 2003 wallpapers in here.

Yeah, this build is almost exactly like XP but with some strange changes

Heh, there is another build of Windows Server 2003 that used a MS Paint edit trick on the branding, too.

Just windows XP with a bull on the bliss wallpaper

Nice

You should check Windows 2000/Whistler/XP build 2210 x64

There is a server 2003 reference

I want that wallpaper
