As one blogger says:
When it comes down to it, Microsoft’s activation system is proving more problematic for legitimate users than it is for the pirates. It doesn’t make sense for Microsoft to impose all these rules and regulations on the consumer when they themselves have built-in a way to bypass their activation system in Vista. C’est la vie.I do not give any moral support to anti-customer device such as this kind of fragile activation scheme. Work around like this is a fair game.
