Some teams use same seals for rear side windows, etc. You can see black battery booster next to right front wheel of Bertelli car on that picture, they used it to remove the window.
If you have broken windscreen you can have 3 mechanics who can remove and clean and put new one during regrouping/parc ferme before the service. Usually (if it's regrouping before the service) you just remove the broken windscreen, clean everything and then put new one in service place.
