I must say, I have had far fewer problems with 7 then with Vista. As for for 7 itself, I have found that programs that state they are made for 7 such as Registry problems, Tweak programs, and Anti-Virus Anti-Spy programs are very well behaved within 7. But, where 7 will please most people is it is less bulky, better user environment, and certainly easier to handle. Vista was certainly not exactly any of the above, and tends to still not be any of the above even with Service Pack 2, which I still consider that one to be something would have been nicer for them to have done a little more with before it was released. Oh well, on with 7 and for once I believe Microsoft may have actually done their best job yet and since XP.
