Yes, they are nice. I spent several hours (!) today on the phone with Microsoft, and they really tried to help. In the end, my issue with installing KB958624 remains unresolved but they acknowledged the problem, suggested meaningful ways to deal with it, and promised that it will be researched and that I will be notified.
More importantly, they listened to my comments concerning Activation. This young, very polite engineer from India with impeccable English listened intently and took notes, appreciating my basic concern: Activation (and copy protection in general) will not stop piracy, but it alienates a company’s best friends, namely its paying customers.
