A decent while ago the Windows XP (nt5/5.1) and Windows NT4 source code was leaked online via 4chan and eventually GitHub. You probably won't see many Windows XP/NT4 systems in the wild, but these are still interesting to look at. The XP source code also includes the source code for IIS and MSMQ in the Source/XPSP1/NT/inetsrv directory. It's technically possible to compile this code into the finished product, but it may require some additional resources not present in the source code leaks
