Primer on Device Support and Testing for Windows 7

  • Comments 58

As most folks (finally) get the beta and start to set aside some time to install and try out Windows 7, we thought it would be a good idea to start to talk about how we support devices through testing and work across the PC ecosystem. This is a big undertaking and one that we take very seriously. As we talked about at the PDC, this is also an area where we learned some things which we want to apply to Engineering Windows 7. While this is a massive effort across the entire Windows organization, Grant George, the VP of Test for the Windows Experience, is taking the lead in authoring this post. We think this is a deep topic and I know folks want to know more so consider this a kick-off for more to come down the road. –Steven

Devices and Drivers in Windows

One of the most important responsibilities in a release of Windows is our support of, and compatibility with, all of the devices and their associated drivers that our users have. The abstraction layer in Windows to connect software and hardware is a crucial part of the operating system. That layer is surfaced through our driver model, which provides the interface for all of our partners in the multi-faceted hardware ecosystem. Windows supports a vast range of devices today – audio devices (speakers, headsets…), display devices (monitors…), print, fax and scan devices, connectivity to digital cameras, portable media devices of all shapes, sizes and functions, and more. Windows is an open platform for companies across the globe who develop and deliver these devices to the marketplace and our users – and our job is to make sure we understand that ecosystem and those choices and verify those devices and drivers work well for our customers – which includes partnering with those device providers throughout the engineering of Windows7.

Drivers provide the interface between a device and the Windows operating system – and are citizens of the WDM (Windows Driver Model). WDM was initially created as an intermediary layer of kernel mode drivers to ease the authoring of drivers for Windows. There are different types of drivers. Class drivers (which are hardware device drivers that supports an array of devices of a similar hardware class where hardware manufacturers make their products compatible with standard protocols for interaction with the operating system) and device-specific drivers (provided by the device manufacturer for a specific device and sometimes a specific version of that device) are the two most common.

Partner Support

Support for our hardware partners comes in the form of the Windows Driver Kit (WDK) and for certification, the Windows Logo Kit (WLK). The WDK enables the development of device drivers and as of Vista replaced the previous Windows Driver Development Kit (DDK). The WDK contains all of the DDK components plus Windows Driver Foundation (WDF) and the Installable File System kit (IFS). The Driver Test Manager (DTM) is another component here, but is separate from the WDK. The Windows Logo Kit (WLK) aids in certifying devices for Windows (it contains automated tests as well as a run-time framework for those tests). These tests are run and passed by our hardware vendor partners in order to use the Microsoft “Designed for Windows™” logo on devices. This certification process helps us and our hardware partners ensure a specific level of quality and compatibility for devices interacting with the Windows operating system. Hardware devices and drivers that pass the logo kits tests qualify for the Windows logo, driver distribution on Windows Update, and can be referenced in the online Windows Marketplace.

Validation and Testing

With Windows 7 we have modified driver model validation, new and legacy device testing, and driver testing. Compared to Vista, we now place much more emphasis on validating the driver platform and verifying legacy devices and their associated drivers throughout our product engineering cycle. Data based on installed base for each device represents an integral part of testing, and we gather this data from a variety of sources including the voluntary, opt-in, anonymous telemetry in addition to sources such as sales data and IHV roadmaps. We have centralized and standardized the testing mechanics of the lab approach to this area of the product in a way that yields much earlier issue/bug discovery than in past releases. We have also ramped up our efforts to communicate platform or interface changes earlier with our external hardware partners to help them ensure their test cycles align with our schedule. In addition, we draw a more robust correlation between the real-world usage data, including recent trends, and prominence of each device and the prioritization it is given in our test labs. This is especially important for new and emerging devices that will come to market right before and just after we release Windows 7 to our customers.

Another important element in bringing a high quality experience to our Windows 7 users in device and driver connectivity and capability is the staging of our overall engineering process in Windows 7. For this release all of our engineering teams have followed a well structured and staged development process. The development/coding of new features and capabilities in Windows 7 was broken out in to 3 distinct phases (milestones) with dedicated integration and stabilization time at the end of each of these three coding phases. This included ensuring our code base remained highly stable throughout the development of Windows 7 and that our device and driver test validation was a constant part of those milestones. Larry discussed this in his post as some might recall. Program Managers, Developers and Testers all worked in super close partnership throughout the coding phases. Our work with external partners – especially our device manufacturer partners – was also enhanced through early forums we provided for them to learn about the changes in Windows 7 and also work closely with us on validation. Much more focus has been put on planning and then executing - planning the work and then working the plan. Our belief is that this yields much more predictability to developing and delivering our new features in Windows 7 both from a feature content and overall schedule standpoint. We recognize that this raised the bar on how our external partners see us execute and deliver on that plan when we say we will, but we also hope it increases their confidence in how they engage with us in validating the device experience during our development and delivery of Windows 7.

Determining Which Devices to Test

Our program management team helps us drive device market share analysis. Most of their data comes from our Customer Experience Improvement Program. This gives us data on the actual hardware in use across our customer base. For example there are over 16,000 unique 4-part hardware IDs for display devices alone. Like many things, we understand that it only takes a single device not functioning well to degrade an overall Windows experience or upgrade—we definitely want to re-enforce this shared understanding.

New devices typically have a small initial user base, but the driver will often be mostly new code (or the first time a code-base has seen a new device). As the device enters the mainstream, market share grows and most manufacturers continue to develop and improve their drivers. This is where for our customers, and our own testing, it’s important to always have the latest drivers for a given device.

Over a device’s lifetime, we work closely with our external device partners and represent as faithfully as possible in our test labs, a prioritized way of ensuring old and new devices continue to work well with Windows. By paying very close attention to trends in the market place across our device classes, we can make guided decisions in the context of these areas:

  • Critical and mainstream devices we must support out-of-the-box
  • Which drivers we must make available on Windows Update
  • On which devices and drivers to focus our testing

Another benefit of close market tracking is creating an equivalence-based view of a device family.

Equivalence Classes

We use the notion of equivalence classes to help us define and prioritize our hardware (device) test matrix. Creating equivalence classes involves grouping things into sets based on equivalent properties across related devices. For example, imagine if we worked for a chemical company and it was our job to test a car polish additive on actual automobiles. Given a fixed test budget, we would want to maximize the number of makes and models we test our product on. We begin by analyzing the current market space so we can make the best choices for our test matrix.

Let’s say the first test car we analyze is a blue 2003 Ford Mustang. We also know that the same blue paint is used on all of Ford’s 2003 and 2004 models and is also used on all of Mazda’s 2005 models. This means our first automobile represents several entries in our table based on equivalence:

Test ID

Year

1

Ford

Mustang

Blue

2003

2

*

Blue

2004

3

Mazda

*

2005

 

Now let’s look at a silver 2001 Mercedes C240. We know that Mercedes and Chrysler have a relationship and upon further investigation we find Chrysler used the same silver paint on their 2006 through 2009 models. Now our equivalence class based test matrix looks like this:

Test ID

By carefully analyzing each actual automobile, we have established an equivalence relationship that we can leverage to maximize implicit test coverage. Testing one make and model is theoretically equivalent to testing many. Of course we recognize in the real world different companies might use different techniques for applying paint, as one variable, so there are subtleties that require additional information to property class attributes for testing purposes.

Testing computer devices is very similar. Even though there are thousands of different devices on the market, many of them share major components, are die-shrinks of a previous revision, or differ only in terms of memory, clock-rate, pixel count, connector, or even the type of heat sink. Take for example display devices. There are over 16,000 display devices on the market. But the equivalence view reveals that 90% of the market is represented by about 60 different GPUs. By adding a few more to a carefully constructed test matrix based on equivalence it is possible to represent over 99% of all GPUs. Driver writers also leverage equivalence by targeting drivers at a range of hardware. Driver install packages indicate devices they support via hardware IDs.

All modern computer devices are assigned a unique hardware ID based on the device vendor, type, and class. Most IDs (PCI, PC Card, USB, and IEEE 1394 devices) are assigned by the industry standards body associated with that device type.

Let’s look at the device ID of my display adapter:

PCI\VEN_10DE&DEV_0611&SUBSYS_C8013842&REV_A2

If I visit PCI-SIG (the standards body associated with all PCI device ID assignment) and do a search on 10DE, I’m told I this is an NVidia PCI ID. If I look further on my system in

C:\Windows\System32\DriverStore\FileRepository

I can find NVidia drivers (folders that start with nv_lh). If I open one of the driver .INF files on my machine I see this tell-tale line:

NVIDIA_G92.DEV_0611.1 = "NVIDIA GeForce 8800 GT”

Further inspection of the driver .INF file tells me that the same G92 GPU is used for all of these devices:

  • NVIDIA GeForce 8800 GTS 512
  • NVIDIA GeForce 8800 GT
  • NVIDIA GeForce 9800 GX2
  • NVIDIA GeForce 8800 GS
  • NVIDIA GeForce 9600 GSO
  • NVIDIA GeForce 8800 GT
  • NVIDIA GeForce 9800 GTX
  • NVIDIA Quadro FX 3700

A bit of online research reveals other interesting information: “The 8800 GT, codenamed G92, was released on October 29, 2007. The card is the first to transition to 65 nm process, and supports PCI-Express 2.0.[13] It has a single-slot cooler as opposed to the double slot cooler on the 8800 GTS and GTX, and uses less power than GTS and GTX due to its 65 nm process.” -WikiPedia

So in theory, if I was to run a test on my display adapter, there’s a good chance I’d get the same results as I would on any of these other related devices.

Driver Goals for Windows 7

One of our primary goals for Windows 7 is compatibility with all Vista certified drivers and to ensure that people have a seamless upgrade experience. This breaks down into several requirements that guide how we test:

  • Drivers for basic functionality are in-box (by in-box we mean available as part of the installation of Windows). This includes drivers for mainstream storage, network, input, and display devices so the OS can be installed and user can get online where, if needed, additional drivers can be acquire from Windows Update.
  • Drivers update and/or install with minimal end user effort.
  • When drivers are upgraded, there aren’t problems with the new drivers.
  • Drivers are reliable.

One question we are asked about quite a bit is the availability of drivers. There are three primary reasons drivers end up looking for folks: clean installation of Windows, attaching device to a new computer, wanting the updated driver. We definitely recognize that for the readers of this blog, both as enthusiasts and often the support/IT infrastructure for corporations, friends, and families, that the ability to acquire drivers and reliably update machines is something of a “hobby” we all love to hate. We all want the latest and greatest—no more and no less.

A clean installation is one we are all definitely valuing during the beta phase of Windows 7. It should be clear that a clean install, as important as it is to many of us, is not a routine/mainstream experience. Nevertheless, the combination of in-box drivers and those available via Windows Update will serve a very broad set of PCs (for example, you should see most of the drivers installed for the new Atom-based machines if you do a clean install). On the other hand, some drivers for PCs are only available from the PC maker and for a variety of reasons are not available for download from Windows Update or even the device manufacturer’s site. For example, mobile graphics drivers are generally available only from the PC maker and not from the graphics component maker—this is a decision they make because of the way these chipsets are delivered for each PC maker.

Obviously attaching an existing device to a new PC is a common occurrence. In this case you may have long ago lost the CD/DVD that came with a device and you just plug it in (because you ignored the warning saying “please run the setup program first”). Again, our goal is to provide these via Windows Update. Often IHVs have updates or significantly large downloads that for a number of reasons are not appropriate to deliver via Windows Update. In that case we can also alert you, with a link many times, to seek the driver from the vendor of the device.

Updating drivers is something we are all familiar with as we often read “get the latest driver” to address issues. We all see this particularly in the enthusiast gamer space where newer drivers also improve performance or offer more features, in addition to improving overall. The primary way to get updated drivers is generally through optional updates in Windows Update, though again many times the latest and greatest must be downloaded directly from an IHV (independent hardware vendor) site.

Our goal is clearly to make sure that drivers for the broadest set of devices are available and high quality. There are many equal partners that contribute to delivering a PC and all the associated devices and we work hard to develop a systematic way to reach the broadest set of customers with high quality software and support.

Scale of Device and Driver Testing in Windows 7

The table below provides examples of some of the explicit devices we have directly tested thus far during the development of Windows 7. This is just a sampling of that direct testing - many more devices have been directly tested that are not shown here or are covered through equivalence classing.

This information is available in many sources, such as the WHQL web site that lists all qualified devices. For the purposes of this blog we thought it would be fun to provide a list here which we think will most certainly serve as the basis for discussion.

  • Please add 8 and 6 and type the answer here:
  • Post
  • Hi Steven, please fix nForce networking problems (it not recognise drivers).

    This is what I call "essentials driver". If I have network working, I can download from Windows Update other drivers.

    (And then not 1gb printers drivers support :D ).

  • @Digi - this may explain why moving USB devices to different ports can trigger an installation:

    http://blogs.msdn.com/oldnewthing/archive/2004/11/10/255047.aspx

  • While I believe the "Device Cleanup Wizard" would have merits I believe that would constitute a feature, and the beta of windows 7 is "feature complete" according to Mike Nash. As far as uninstalling drivers Microsoft should raise the bar for it to be a singed driver. I have seen lots of issues in windows because drivers would not un-install properly. This is not Microsoft's fault but they could enforce a more stringent standard for un-installing drivers before giving the driver a signed status.    

  • My mobility Radeon 9700 was not recognized by Windows 7 but it did recognize Linksys PCI Wireless card( thats good i guess).

    I downloaded and installed Windows 7 on my Dell Inspiron 9100. I did see a Blue screen of death while installing VPN client and later i had to restore it back original configuration. but so far its running ok and boots better than Vista and wakes up faster from Sleep.

    Do we have to UnInstall and do a fresh install when Windows 7 get released or we get updates?

    Thanks

  • Steven,

    First and foremost, congrats on getting the beta out. I am writing this to you on Windows 7 Beta 1 Ultimate 64 bit. The fact that I can write to you on Engineering Windows 7 is major credit to your team. The work isn't over but the fruits of your teams labor can be seen.

    But on a side note, my computer has improve TONS using Windows 7. I don't think I want to go back to Vista. LOL! Great job so far!

    My question has to do with companies who aren't assisting you with Drivers and Device Support. How are you guys handling a company or competitor who might not reveal that kind of sensitive information to Microsoft or the Windows 7 Team? Are you guys going so far as to bring those devices in and figuring out support from scratch? There are several instances where companies may not want to cooperate. Apple and Google come to mind along with their phones, music players, and other devices. This also includes devices that I saw on G4's CES program that use Open Source OSes. Granted that most would because with a billion users, Windows is so very ubiquitous. It would just be interesting to understand the methology when you have to support a device in which that company wouldn't be fully cooperative.

    Thanks for the blog and the stellar beta. Can't wait for the RC!

  • While I've enjoyed all of the entries in this blog, there is an elephant in the room, and that elephant is DRM.

    I want to know how the Damned Restrictions Management are going to affect:

    - Playback of my music

    - Playback of my videos

    - Hard drive life

    - Battery life

    - Overall computer performance

    I'm amazed that this exceptionally important subject has not yet been addressed.

  • As noted in the article, the same chip is used in different devices. Will Windows suggest a generic driver where a manufacturer-specific one is lacking? Or an alternate manufacturer's driver for a device that uses the same chipset?

    I've seen Generics in the windows driver database, but unless you know what chipset your card uses, you're out of luck.

    Additionally, if Windows can't find any drivers, would it be possible to provide, up-front, the information that might be required to search for the correct driver?

    Telling me I might want to go to Nvidia.com for my graphics card driver definitely puts me on the right track, but I'm not sure if the fact that "Nidia is the manufacturer" was new to me, that I would know what to do when I got there.

    Doing that PCI-SIG lookup with the PCI ID would be good - maybe even advise that I pull the card and look on the board, or read the serial number from the bottom of the device -- anything to help.

  • @Dean Harding,

    yes, sorry, I can't find it right now. Maybe I have mixed sites and article was somewhere else...but still:

    Microsoft depends on customers. And they're asking and asking and asking and are afraid about such things like DRM or similar...and they like more older XP (see "Ed Bott: If you love Windows XP, you'll hate Windows 7" and other in http://news.zdnet.com/2463-9595_22-246570.html). If XP works better for many of them (and will be in many typical tasks, because runs the smallest one amount of code), why not mix the best things from Windows 5.x and 6.x and make really great release ?

    7 seems to resolve some issues, but adds new one...many new one (this time definitely see link for zdnet.com articles).

    You can say in this moment of course, that I'm against changes. No, it's not. I was testing Vista, Server 2008 and now 7. And still I can't do something inside. Starting from such easy things like entering "C:\Documents and Settings" (yes, I know it's link, but FAR for example doesn't have problem with it) or creating icon for enabling/disabling network interface, ending on removing useless system components... And still virtual machine with XP is smallest one (on HDD and in RAM) and works the faster.

  • I know, that my previous post was maybe a little controversial, but I'm looking into the smallest one Windows 7 features and have very mixed feelings.

    Example: such easy feature like Clear Type tuner. It was such application developed by Microsoft for Windows XP and it had wizard + options for manual tuning. In Windows 7 options were removed and wizard has got 4 steps (instead of 2 like earlier).

    I'm sorry, but creating innovations for any price sometimes make, that things are going to be difficult. Why not give people what they want ?

    Creating XP with all patches, .NET versions, updates + some generally good estimated Windows 6.x features (like loading DLLs in random places) can be very good estimated by market... Short work, less problems with optimalizing. It could give developers time for working on sandboxing applications and other security things...

  • @im.thatoneguy

    @kudraw

    I have Asus P5n 650 SLI Nvidia (intel)

    Work perfect with Seven

  • @Domenico: I'm referring to nForce2/3 series, that works good with Windows Vista, but in Seven there is a problem with the NForce Network Controller.

  • I am very impressed with the fact every device that I have used or installed has worked or that there is a work around, except for Legacy IR support I have no complaints, the only device that missed in the installation of Window 7 beta it installed in the PDC build so it will be resolved before release.

    I use some fairly exotic hardware peripherals and the software, devices and drivers seem to interface very well.

    I was expecting some trouble with the new build but have found it to be a nearly finished OS and I have found that most non plug and play devices work...CCD Cameras, Optical Devices and Robotic drives.

    Good work, I will be pushing the OS in my side business.

  • I'd like to thank the windows team to have make our life so much easier with the drivers being directly downloaded from the Internet (it was already in place in vista, yes but its much better in seven)

    being able to export specific or all our driver and being able to import them again directly from windows would be a good idea as you may very well know formatting and reinstalling windows is part of almost every windows user and easing this task would be greatly appreciated.

  • @kudraw

    Try Vista Driver with this method

  • Hi Steven,

    first of all, i must congratulate for pulling Windows 7-Beta so far. I really enjoyed every minute I was using W7.

    On the topic of drivers, any one noticed how robust the initial VGA generic driver is? You get all those little lights in the task bar, the desktop is crisp, it is really nice. And as soon as I was online it downloaded all the drivers (Realtek wireless card, ATI Radeon X1200)..

    Keep up the good work team.. I am waiting for the final release now.. Hopefully Ultimate version will not be way above my budget :)
