This is why I will never buy Vista. So in my eyes it is a rip off and not a good idea Thank OvenMaster for the article

"Vista's legal fine print includes extensive provisions granting Microsoft the right to regularly check the legitimacy of the software and holds the prospect of deleting certain programs without the user's knowledge."
and
"Once operational, the agreement warns that Windows Defender will, by default, automatically remove software rated "high" or "severe," even though that may result in other software ceasing to work or mistakenly result in the removal of software that is not unwanted."
and
"For greater certainty, the terms and conditions remove any doubt about who is in control by providing that "this agreement only gives you some rights to use the software. Microsoft reserves all other rights." For those users frustrated by the software's limitations, Microsoft cautions that "you may not work around any technical limitations in the software."
Those technical limitations have proven to be even more controversial than the legal ones.
Last December, Peter Guttman, a computer scientist at the University of Auckland in New Zealand released a paper called "A Cost Analysis of Windows Vista Content Protection." The paper pieced together the technical fine print behind Vista, unraveling numerous limitations in the new software seemingly installed at the direct request of Hollywood interests.
Guttman focused primarily on the restrictions associated with the ability to play back high-definition content from the next-generation DVDs such as Blu-Ray and HD-DVD (referred to as "premium content").
He noted that Vista intentionally degrades the picture quality of premium content when played on most computer monitors.
Guttman's research suggests that consumers will pay more for less with poorer picture quality yet higher costs since Microsoft needed to obtain licences from third parties in order to access the technology that protects premium content (those licence fees were presumably incorporated into Vista's price).
Moreover, he calculated that the technological controls would require considerable consumption of computing power with the system conducting 30 checks each second to ensure that there are no attacks on the security of the premium content."
