The feature of the win 7 depends on the comparison. Like in comparison to which one like we all know now we have one more advance version of the win 7 which is going to release soon. If we compare it with XP or Vista then there will be some different points. Anyway i will say win 7 is the good O.S. and is best facility is the troubleshooter.
