Why Windows Vista Ended Up Being a Mess (usejournal.com)

alaskana98 shares an article called "What Really Happened with Vista: An Insider's Retrospective." Ben Fathi, formerly a manager of various teams at Microsoft responsible for storage, file systems, high availability/clustering, file level network protocols, distributed file systems, and related technologies and later security, writes: Imagine supporting that same OS for a dozen years or more for a population of billions of customers, millions of companies, thousands of partners, hundreds of scenarios, and dozens of form factors -- and you'll begin to have an inkling of the support and compatibility nightmare. In hindsight, Linux has been more successful in this respect. The open source community and approach to software development is undoubtedly part of the solution. The modular and pluggable architecture of Unix/Linux is also a big architectural improvement in this respect. An organization, sooner or later, ships its org chart as its product; the Windows organization was no different. Open source doesn't have that problem...

I personally spent many years explaining to antivirus vendors why we would no longer allow them to "patch" kernel instructions and data structures in memory, why this was a security risk, and why they needed to use approved APIs going forward, that we would no longer support their legacy apps with deep hooks in the Windows kernel -- the same ones that hackers were using to attack consumer systems. Our "friends", the antivirus vendors, turned around and sued us, claiming we were blocking their livelihood and abusing our monopoly power! With friends like that, who needs enemies?
I like how the essay ends. "Was it an incredibly complex product with an amazingly huge ecosystem (the largest in the world at that time)? Yup, that it was. Could we have done better? Yup, you bet... Hindsight is 20/20."

From what I remember:

1. They tried to write big chunks of it in .NET which wasn't quite a mature framework yet, and...
2. They tried to component-ize everything into discreet, independent modules, and once they brought all of the modules together to compile as one coherent OS, it failed miserably

They are still trying to do step #2 - witness the ARM based windows they are still working on, and Windows running on the XBox One, etc..

How MS played the incompatibility card against DR-DOS

"It's pretty clear we need to make sure Windows 3.1 only runs on top of MS DOS or an OEM version of it," and "The approach we will take is to detect dr 6 and refuse to load. The error message should be something like 'Invalid device driver interface.'" Microsoft had several methods of detecting and sabotaging the use of DR-DOS with Windows, one incorporated into "Bambi", the code name that Microsoft used for its disk cache utility (SMARTDRV) that detected DR-DOS and refused to load it for Windows 3.1. The AARD code trickery is well-known, but Caldera is now pursuing four other deliberate incompatibilities. One of them was a version check in XMS in the Windows 3.1 setup program which produced the message: "The XMS driver you have installed is not compatible with Windows. You must remove it before setup can successfully install Windows." Of course there was no reason for this. Brad Silverberg, the Microsoft exec who finally left the company last week, but who in an earlier life had been responsible for Windows 95, emailed Allchin on 27 September 1991: "after IBM announces support for dr-dos at comdex, it's a small step for them to also announce they will be selling netware lite, maybe sometime soon thereafter. but count on it. We don't know precisely what ibm is going to announce. my best hunch is that they will offer dr-dos as the preferred solution for 286, os 2 2.0 for 386. they will also probably continue to offer msdos at $165 (drdos for $99). drdos has problems running windows today, and I assume will have more problems in the future." Allchin replied: "You should make sure it has problems in the future. :-)", which is clear enough, and it should be noted that the pair were both high level Microsoft executives.

I don't know much about Silverberg, but I can say I never read an article about Allchin where he didn't come across as a world-class slime weasel.

Jim Allchin

After serving sixteen years at Microsoft, Allchin retired in early 2007 when Microsoft officially released the Windows Vista operating system to consumers.

Perhaps in 2023 (2017 + sixteen years) we'll all be able to let bygones be bygones.
