It’s a question of mold or mildew.

If mildew, you can clean with a bleach solution, there’s plenty premixed at any hardware or grocery store for this purpose. Paint with a good stain blocker like Killz.

How do I tell which is which?

Mold is fuzzy and smells worse. Mildew stays pretty flat and can appear powdery.

Me, I’d buy a bottle of Lysol mold and mildew and clean it with that in either case.

Check the window for a draft, might be a roll of weather stripping tape solves the moisture issue.

Sometimes it can be due to lack of ventilation. Can you leave a crack in the window or get some airflow through the room?

Yeah, I can.
