Be happy, at least neither are a moving violations. At least you're insurance won't go up. Did you actually get a ticket for the windows? First of all check the NY law about the tint, and make sure that it is actually illegal. If it is illegal, than there isn't much that you can do, other than fix it.

You could get a ticket for no registration sticker even if you have paid the registration fee. Because it is required by law to affix the sticker. If you paid ur registration fee, but didn't put the sticker on, the fine would probably be just the processing fee for the ticket. If you didn't pay, you will certainly be fined by the court, along with DMV registration + a % of the registration for non-payment.
Tickets are issued to the vehicle's registered owner when driver could not be identified

If it is on the road...I would think yes. If it is in a driveway or private property...NO!
