they are very nice but i think some of them are not of your own conception, talking about all the "vista ..." and maybe some other one, you can't upload a png that you didn't create, or at least, modified a lot.
waiting for an admin advice ...


edit : ok sorry i've just seen on CrXP a pack of the 2 vista folder psd made by you, you re-created those icons completly so i think it's fine
sorry again for my suspicion , your icon's are great !
