Dell Documents Reveal Microsoft's Pre-launch Vista Errors
twitter writes "The New York Times has a piercing analysis of documents from the Vista capable lawsuit. The documents show that Microsoft seems to have put a wrench in Vista's driver situation only at the last minute. 'Late OS code changes broke drivers and applications, forcing key commodities to miss launch or limp out with issues,' said one slide in a Dell presentation dated March 25, 2007, about two months after Vista's launch at retail and availability on new PCs.' We have all heard the lazy vendors don't believe Vista will launch excuses but few of us have heard Steven Sinofsky, chief of Windows development, second and third opinions. 'Massive changes in the underpinnings for video and audio really led to a poor experience at RTM,' he said. 'This change led to incompatibilities. For example, you don't get Aero with an XP driver, but your card might not (ever) have a Vista driver.' Finally, said Sinofsky, other changes in Vista blocked Windows XP drivers altogether. 'This is across the board for printers, scanners, WAN, accessories and so on. Many of the associated applets don't run within the constraints of the security model or the new video/audio driver models.'
The quotes in the summary explain why Windows XP drivers would not work; they do not state that driver model changes were made right before RTM.
Turn off thumbnail generation. The DRM is only used for playback of protected files.
First off, it's well known that the redone video and audio drivers were required for the new DRM. That right there is a change: pre-Vista, the OS wasn't designed explicitly for DRM. Now it is.
Secondly, the new designs shave a good 10%-50% off performance. Audio acceleration is gone. EAX effects are no longer possible. Recording the audio output of programs is no longer possible. All in the name of DRM.
ALL layers are now encrypted. This, not surprisingly, slows down the OS. By a lot. It also greatly reduces battery life. Where before, playing a music file might involve a single decryption step to send the data to the audio player, it now must be re-encrypted before being sent to the card, then re-decrypted before being converted to analog. All because an enterprising user might otherwise snoop on the bus to "steal" the audio data.
In short, Vista is 10%-50% slower solely to allow for DRM. The kernel was redesigned with DRM in mind, not user experience. Battery life was halved in extreme cases - again, solely for DRM.
It's not trolling, there are simple facts that have been exposed time and time again. Look it up on Google. Vista is much, much, much worse than XP when it comes to DRM.

While it goes into details about a lot of other stuff, there's the explanation of Vista's (apparent) slow disk performance.

Late OS code changes broke drivers...
This reminds me of the painful driver development from NT4 to Windows 2000. A few years before release MS was pushing us to port NT4 drivers to Win2K. We jumped on it quickly and had working drivers, but as the years rolled by changes would be made that broke the earlier work. This rinse and repeat continued to the *very* end. Years of wasted time and resources for no reason.
What I learned from that is to start looking at new Windows driver documentation a few months before release and then wait until the actual release before changing or writing any code. You just don't know what fundamental changes will occur until the discs are on retail shelves.
You sure as hell can't trust what MS tells you as a developer about interface changes and release dates.
Microsoft hashed the release of Vista, but the Linux community of all people has no right to talk about new releases making drivers incompatible. Backwards compatibility doesn't exist in the linux world.
Examples please. All my devices work the same or better under SuSE or Ubuntu.
All my purchased Linux (Loki) games still work.
I can't say that for my $300 Microsoft Office 6.0 purchase under Windows. I can't say that either for the Windows games I've purchased over the years.
Enjoy,
It's just the normal noises in here.
