Yes MSXML3 is shipped with Vista and W7 (along with MSXML6 in so-called side-by-side installation).

You can install MSXML6 on the following Windows versions

1. Windows 2000 Service Pack 4
2. Windows Server 2003;
3. Windows Server 2003 Service Pack 1;
4. Windows XP Service Pack 1;
5. Windows XP Service Pack 2
