1. You didn't buy windows live messenger, or an account for it
2. They don't need to enforce the EULA even. They can just disconnect clients from their network as they see fit. You have no entitlement to use their service what so ever.
Well, this is going into legal space, where the rules of logic can be warped or suspended. <play x-files title music>
This depends on where I got the copy of said messenger from. When it comes as part of a legitimate Windows-CD, I can buy it. Even if it is only some add-on. I have bought it because it contains that messenger, and I want to use it. When they
then, after the purchase, try to change the contract (I bought that thing without that restriction), that restriction is void. I did not see it before purchase, I cannot return that product since I already installed and launched it once. Trying to block me using my legally bought SW can bring them into breaking that first contract of purchase, which would entitle me to a refund and compensation for damages/time/efford. A landsh.. lawyer would now say that "this is going to be one interesting case", which is their lingo for "I'll order my new sports car, and you will be the one paying it."
This is not only for that messenger, but for almost any EULA pushed into your face while installing something. It has already been ruled that these are presented too late, and thus are not binding. Now imagine a Windows-DVD where the complete EULA is printed out and attached at the outside of the case so you can read it all before shelling out the money. And that would only protect them at these sales, not with the pre-installed systems where you would have to have the chance to read each&every EULA for all the added tools.
Bottom line, should this end in court, it would possibly take ages to decide and make some lawyers rich. Much easier to steer clear of them.
