or any other software company for that matter to submit their End User Licence Agreement to our government for its perusal. If you create something - a photograph say - you automatically have the copyright in that image. Nobody (not even the people in the photo) can reproduce or distribute the image without obtaining a copyright licence from you, and you don't need to submit your licence terms to anyone for approval - they are your terms, and if a prospective licencee doesn't like them he/she doesn't have to buy your licence.
It's exactly the same with software. Microsoft has created Windows XP (to use an example) and the company owns the copyright in the software. They'll sell you a licence to use it, but you must agree to their licence terms and conditions if you do use it. The copyright owner can apply whatever terms and conditions he/she likes, provided that compliance does not involve having to act in any way illegally. Nothing in the Microsoft EULA requires you to act illegally, and so it needs no approval from anyone. Companies that size will have ensured that every single word of their licence has been scrutinised by expensive corporate lawyers - to ensure that it's as watertight as it can be.
