How to remove a sticker from the inside of a car windshield which I want to leave undamaged so that it can be used on another car. The stickers are for car insurance, road tax (vignette) or other similar. 

Lets say if they were applied on the wrong place or the wrong car and I want to move them, then I need to take them without damaging.
