When it is windy outside I get a draft in a few windows but the draft is from poor insulation from when they were installed. Any suggestions on how I can insulate without destroying the window sill?

Thanks for your question.
There are several ways to insulate the window without a lot of mess.
The first option is to insulate with spray foam in a can that you can purchase from any hardware store ( make sure it specifies for windows and doors) , make a small hole the size of the the nozzle that is on the can, you want to make a hole at each corner. You want to make the hole directly next to the window trim where it meets the drywall and start spraying into the holes.
This way is tricky because you do not exactly how much to spray.
The second option and best way is to remove the window casing completely from the window and spray foam around the window from the inside where you removed the trim, you need to beware that the foam expands so you will want to add just a small amount until you know how it will expand. Reinstall the trim, caulk and touch up paint.
This should help with the air leaks around the window.
Good luck.
