Hey, seeing as you are new to the domain scene, welcome! These domains are trademarked so I suggest dont register anymore and try and delete these. If you look at Microsofts history they will quickly serve you up papers for domains like this. I still remember the MikeRoweSoft case with a teenage boy from my home province of BC. I would suggest you do more research on what makes a good domain name and focus on generics and other non TM names. Good luck!
