The Associated Press has released a news article about Microsoft restricting virtualization on their Windows operating systems.

The main issue is that Parallels, a company that sells virtualization products, has a software that can run Windows XP and Windows Vista in the same computer at the same time. The catch here is that users cannot buy just the Home Basic nor Home Premium versions of Vista, but they have to buy the Business version, which is $100 more expensive than Home Basic, or the Ultimate version which costs twice as much as the Home Basic version.
