Microsoft’s Windows XP and Windows Server 2003 source code leaked online

The source code for Windows XP SP1 and other versions of the operating system was allegedly leaked online today.

The leaker claims to have spent the last two months compiling a collection of leaked Microsoft source code. This 43GB collection was then released today as a torrent on the 4chan forum.

This is a massive leak of old code, and other than Windows XP, it also includes Windows Server 2003 and various versions of MS-DOS and Windows CE. One of the funnier tidbits we've already learned from the leak is that Microsoft was working on a Mac OS X Aqua theme for Windows XP, probably just to see if they could.

I doubt much of this code will be useful to any serious projects, since no serious developer working on things like ReactOS or Wine will want to be found anywhere near this code. That being said, individuals, tinkerers, and those crazy people still making community-updated builds of Windows XP will have a field day with this stuff.
