windowserver is a core component of macOS. It is essential and you cannot delete it.
Everything that has to do with your screen involves windowserver. If you have multiple apps open or multiple windows in an app, close some of them. If you are gaming or watching videos that will increase windowserver CPU usage. Ditto using multiple displays.
Users have reported that reducing transparency can lower windowserver CPU usage. Try watching How to Tame Liquid Glass for some suggestions.
