Windows 2000 build 1528 is an unleaked build of Windows 2000 which is briefly mentioned in shell\lib\i386\readme.txt from the Windows XP Service Pack 1 source code.

USER32P.NT4:  This is actually taken from NT 1528, but it has the
right exports needed for desknt4.cpl.  The exports changed in the 
real user32p.lib, so we need this to link to.

Various files in Internet Explorer 5 build 0910.1304 for SPARC also have the version number.
