At this point, every ms customer should stop complaining. MS knows what you think about it, and ignores you. Look at your options rationally:

You can chose to live with it and bitch. Sorry, dont expect anyone to care, you preferred it over the alternatives.

You can mess with the registry/ group policy/ whatever. It will take you a few hours, and in a few weeks you'll have to do it again. You'll never be in the lead. If that's your choice, so be it, but be honest: you wanted this more than any alternative.

You can go to linux. Things will be better, but not perfect, and there will be an uncomfortable learning curve of a few weeks. Bonus points if you reclaim the money for the license. More bonus points if you give some money to the linux ecosystem.

You can go to OSX, and deal with the walled garden. Life will be good, as long as you can live with whatever apple thinks is best.

You can contact local politicians, consumer groups, etc...

You can sue microsoft. Really. Especially in the EU, if you thoroughly do your homework, you have a reasonable chance of winning. Somebody complained about seeing the license only after having paid for windows, sued and won. After that ms printed the url to the license on all their EU windows boxes.

You can contact ms support and complain. They will notice if their decisions make their support costs raise.

Each non ms option causes some short term discomfort, but each small drop eventually wears down a mountain. Make your choice and live with it.
