>Window managers are a class and you should not be able to monopolize a class name without some sort of addition. The Windows trademark is for the entire operating system product. It's not just for the window manager. Keep in mind that trademarks are incredibly specific. Infringement only occurs if it's a similar product. For example, there is a recreational vehicle company named Starcraft that has been in business since the early 1900's. Blizzard made the real time strategy game called Starcraft. Both usages of the word "Starcraft" are registered trademarks, and do not infringe on each other.
