Microsoft: Legit Windows or no updates: I found this via Techdirt which comes to the same conclusion I have: the more Microsoft does things like this to prevent piracy, the more Microsoft alternatives will thrive.
Aiming to crack down on counterfeit software, Microsoft plans later this year to require customers to verify that their copy of Windows is genuine before downloading security patches and other add-ons to the operating system.
Microsoft Office software activation, for instance, was the best thing that could have ever happened to WordPerfect or Open Office. With Office XP, having to activate the software suddenly made it very hard to install multiple copies of the same Office CD on different computers.
If they’re forced to buy multiple copies of Office, a certain percentage of people are going to go looking for alternatives. These changes by Microsoft to stem piracy are just adding straw to the camel’s back.
