    Default Microsoft Windows Vista will break your computer if you illegally download


    Vista crippled by content protection

    By Chris Mellor, Techworld

    PC users around the globe may find driver software is stopped from working by Vista if it detects unauthorised content access. Peter Guttman, a security engineering researcher at New Zealand's university of Auckland, has written A Cost Analysis of Windows Vista Content Protection. He reckons Vista is trying to achieve the impossible by protecting access to premium content. Users will find their PCs' compromised by the persistent and continuous content access checks carried out by Vista.

    Gutman thinks these checks and the associated increased in multimedia card hardware costs make Vista's content protection specification 'the longest suicide note in history.'

    The core elements in Vista have been designed to protect access to premium content. The design requires changes in multimedia cards before Microsoft will support them for Vista use.

    Content that is protected by digital rights management (DRM) must be sent across protected interfaces. This means cards using non-protected interfaces can't be used by Vista PCs.
    Disabling and degrading

    Vista is disadvantaging high-end audio and video systems by openly disabling devices. The most common high-end audio output interface is S/PDIF (Sony/Philips Digital Interface Format) which doesn't have any content protection. It must be disabled in a Vista system when DRM-protected content is being played. Equally a high-end component video interface (YPbPr) also has no content protection and must be disabled when protected video is being played.

    - Vista covertly degrades playback quality. PC voice communications rely on automatic echo cancellation (AEC) in order to provide acceptable voice quality. This requires feeding back a sample of the audio mix into the echo cancellation subsystem, which isn't permitted by Vista's content protection scheme. This lowers PC voice communication quality because echo affects will still be present.

    - This overt and covert degrading of quality is dynamic, not consistent. Whenever any audio derived from premium content is played on a Vista PC, the disabling of output devices and downgrading of signal quality takes place. If the premium content then fades away the outputs are re-enabled and signal quality climbs back up. Such system behaviour today indicates a driver error. With Vista it will be normal behaviour.

    - Vista has another playback quality reduction measure. It requires that 'any interface that provides high-quality output degrade the signal quality that passes through it if premium content is present. This is done through a "constrictor" that downgrades the signal to a much lower-quality one, then up-scales it again back to the original spec, but with a significant loss in quality.' If this happens with a medical imaging application then artifacts introduced by the constrictor can 'cause mis-diagnoses and in extreme cases even become life-threatening.'
    CPU cycle guzzling

    The O/S will use much more of a PC's CPU resource because 'Vista's content protection requires that devices (hardware and software drivers) set so-called "tilt bits" if they detect anything unusual ... Vista polls video devices on each video frame displayed in order to check that all of the grenade pins (tilt bits) are still as they should be.'

    Also 'In order to prevent tampering with in-system communications, all communication flows have to be encrypted and/or authenticated. For example content sent to video devices has to be encrypted with AES-128.' Encryption/decryption is known to be CPU-intensive

    Device drivers in Vista are required to poll their underlying hardware every 30ms - thirty times a second - to ensure that everything appears correct.

    It is apparent that Vista is going to use very much more of a PC's resources than previous versions of Windows and degrade multi-media playback quality unless the user has purchased premium content from a Microsoft-approved resource.

    Such over-reaching by Microsoft could prove to be the catalyst needed to spur increased takeup of Linux desktop operating software, or of Apple's Mac OS.

    Are you fucking serious? Microsuck is trying to moralize the fucking planet, which is an impossible task... and in doing so, they're churning out substandard products that have the temerity to decline to work should it not like your particular setup.

    I'll hang on to the winblows i have, then buy a mac for the next computer. I don't relish corporations trying to impose their ethics on me.

    Mac's no better with DRM. However I get the feeling Mac's DRM only exists as a barebones to run their iTunes. Like see? We do have a DRM, but it basically does nothing.

    I have had a play around with a trial version of Vista. One of my flatmates is in I.T.

    You have no idea. To run Vista, everyone is going to have to upgrade like crazy. Something like a minimum of 1 GIG of free RAM memory just to get the thing moving.

    Fuck that. Next computer is a mac.

    I was thinking about getting this when it came out (my computer is brand new and Vista ready) but I've decided not to, is anyone ACTUALLY planning on purchasing it? Most people I know aren't all that interested it.
    All you can do at life is play along and hope that sometimes you get it right.

    I just bought a new laptop one year ago with Windows XP and Office 2003, etc. and I have no intention of being suckered or shotgunned into buying another frickin' computer with a non-debugged-yet system, that crashes me when I download. I'll bet it does a lot more than that, too.

    I installed a beta version of Vista months ago and never use it. First off my soundcard doesn't work with it!!! I've heard a lot of people having issues with their soundcards as well. Also, I know it's a beta and all but it was crashing all the time. My system is more than well-equipped to handle Vista too. No Vista for me, I'm going Mac.

    I do know a lot of people that are stoked about Vista though. I think that's only because I live in Seattle.

    This stuff is really pissing me off. I did some updates recently (windows and IE) and now I can't play CNN videos, etc. All these damn companies trying to be so proprietary is disgusting. You guys are actually convincing me that -- gasp -- I might go Mac after all these years. My laptop is only a year old and it's perfectly acceptable and functional, but I suspect it will not handle Vista.

    Well I guess I'd better start researching and saving my $$ now. I'm NOT succumbing to Vista. I never was much of a Gates disser, but there's plenty of time (and reason) to start.

    Eww.. this sucks I think I might join the MAC side too when I need a new computer. I have no experience with MAC products, but I can learn.
