do I really need to update service pack for hoster 4.0

Make sure you have your auto updates installation off. You can have the auto update feature off too if you want, so there won't be any changes to your computer. Also, always remember a date that your computer is without a problem following and update installation or adding any software so you could always go back to a restore point. Just do updates if you think you needed it, if everythings seems to be working fine just leave it like that. Remember it is only recommended to have all those updates if needed.
