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.'
I am wondering what went wrong to force Microsoft to change kernel and break drivers at the last minute. Because of a design flaw that compromised security? Or DRM?
Many of the associated applets don't run within the constraints of the security model or the new video/audio driver models.
When rebuilding a system from the ground up for security, these issues need to be hashed out first. The fact that the security and driver models were changing significantly shortly before launch is a sign of bad design. Or at the very least horrible project management. If Vista was in the works for over 5 years, and it was designed properly from the start, 3rd parties should have had plenty of time (years) to conform to new models.
Developers: We can use your help.
The driver models for audio and video in Vista are drastically different than they were in XP. Microsoft is trying to push towards a more microkernel-ish model where these drivers are intended to exist in user-mode. The entire Vista audio stack is user-mode and the video stack is divided into two portions where a good 90% exists in user mode and the rest remains in kernel mode for performance reasons. Microsoft is also trying to force hardware scheduling to prevent a single accelerated application from hosing an accelerated desktop, which is currently a problem in all accelerated desktops, Compiz and OSX included.
The driver situation wasn't any better when XP was launched. If anything it was much worse because all of a sudden consumer-grade hardware vendors had to jump to supporting the NT kernel rather than the 9x kernel, which finally locked down the memory isolation so that a user-mode app could not access kernel resources. It took years for the big companies like Creative Labs, nVidia or ATI to get half-decent drivers out for XP. The situation for Vista is already much better than it was for XP.
All the more reason to avoid release dates. Whether it's completely arbitrary, or it's an estimate given by a developer, release dates only result in two things: Making people rush, and making products late or not as advertised.
I can understand a statement such as "We hope for our product to be ready by [date]" or "We're aiming for a possible launch window of [date]", but to say "Our product will be available on this date" only puts pressure on those lower down the totem pole, and can result in a lot of lost features or quality assurance.
Conversely, this should not be used to infer the Duke Nukem Forever will be an awesome game if it is ever released.

Perhaps, one day, when competition re-emerges in the OS marketplace, microsoft will have to clean up their act. Until that day, and as long as people keep giving microsoft their money, nothing will change.

The reason I ask is because it's possible that Dell's contracts with Microsoft did, in fact, obligate them to promote Vista by the stickers on computers. For instance their bulk discounts are tied to various deals, such as having "Dell recommends Windows Vista" on their website.
Also worth noting is that many OEMs were shipping systems with "Vista Ready" stickers long before Vista was finalized. They had no way of knowing how well Vista would ultimately run on the machines, other than what Microsoft was telling them. Still, the OEMs share the blame to the extent that it was irresponsible of them to trust Microsoft and put stickers on systems without being sure that their claims were correct.
No it's not. It's just more Microsoft marketing-speak. For example:
The new video and audio drivers have nothing to do with DRM.
Reasons include moving as much software out of kernel mode as possible thereby minimizing bug checks (in layman's terms "BSODs"), developing an architecture to make debugging audio problems in applications easier, and supporting a whole new generation of Digital Rights Management (http://www.microsoft.com/whdc/device/stream/output_protect.mspx) Vista is not 10%-50% slower. Of course, none of this bodes well for Vista, which is now more than 2x slower than the most current builds of its older sibling. Either Microsoft supports it, or Microsoft can kiss all high-def media good-bye.No, if Microsoft doesn't support it, we can ALL kiss DRM'd high-def media good-bye, and good riddance. Microsoft had been a key supporter and booster of computer DRM despite their customers' distaste for it. Don't try to pretend they are anything but complicit partners with the studios in this.
