Microsoft I.C.E.

It a free program that allows Microsoft to create panoramic pictures with ease. And it fully automatic (though the pictures should be numbered correctly), and requires no special effort or knowledge by the user.
And with wonderful preview, which gives you a pretty good idea of the final result. The quality of the resulting panoramic picture is excellent, only sin that in some cases (at least among the tests I did) there was some slight burr in one of the junctions between the pictures (while the preview was absolutely perfect).
Overall, the program is very good, especially for beginners.
