Driver Updates Can Cause Vista to Deactivate

WARNING: device driver updates causing Vista to deactivate

After weeks of gruelling troubleshooting, I've finally had it confirmed by Microsoft Australia and USA -- something as small as swapping the video card or updating a device driver can trigger a total Vista deactivation.

Put simply, your copy of Windows will stop working with very little notice (three days) and your PC will go into "reduced functionality" mode, where you can't do anything but use the web browser for half an hour.

You'll then need to reapply to Microsoft to get a new activation code.

How can this crazy situation occur? Read on for the sorry tale.

The Problem

Just over a month ago I swapped over the graphics card on my Vista Ultimate box. There were some new DirectX 10-based titles out and I couldn’t get the benefit on my old DirectX 9 card. The swap-over went well and I went on my merry gaming way.

Then a few days ago I got a Windows Activation prompt – I had three days to activate Windows or I’d be bumped back to RFM (Reduced Functionality Mode). What the? My copy of Vista was activated, and a graphics card change shouldn’t have triggered deactivation... surely!

I was able to reactivate easily enough, although as the product key was already in use (by me!) I couldn’t reactivate automatically, but had to speak to a Microsoft customer service representative.

I got the code easily enough, but it didn’t explain why Vista had deactivated, so I got in touch with Microsoft about the problem.

They sent me some special utilities to run which gathered the history of hardware changes on that machine since activation, and it turns out that my disk controller had changed, so the graphics card change was the final change which tripped deactivation.

The only problem? I had never changed my disk controller at any point. Apparently because I had upgraded the Intel Matrix Storage Manager application, this was reported as a major hardware change event.

On their own, neither event was enough to trigger deactivation, but cumulatively they were.

The Activation Process

The documentation is still being updated by Microsoft, but the activation process for Windows Vista and Volume Activation 2.0 is essentially unchanged from Windows XP, except that with Vista it’s supposed to be more tolerant.

When the machine is first activated, Windows establishes a baseline based on the installed hardware, but interestingly the information is not gathered from hardware IDs (which are not necessarily unique), but from hardware information as reported by device drivers. Any changes away from this baseline are weighted depending on the change (for example, a new CPU counts much higher than new RAM) and once the baseline threshold is passed, Windows deactivates and a new activation request is generated.

The problem with using device drivers as the basis for activation information is that a change in the driver model which has the result of changing the way that the hardware information is reported back to Windows can be enough to register as a physical hardware change.

For example, if you install and activate Vista using some Microsoft drivers downloaded from Windows Update (which is a very common practice) but then discover that a manufacturer driver gives better functionality (as is often the case for audio, video, storage and network drivers) you are running the risk that the drivers use different reporting models and will register as a physical change.

So what this essentially means is that keeping your drivers up-to-date is a potentially very risky process, with all changes monitored and changes weighted cumulatively.

The Problem with Activation

As most tech enthusiasts would be aware, activation (and particularly Volume Activation 2.0 which is applied to every version of Vista available), is designed for one thing – to curb piracy.

The idea is that Windows monitors the hardware it’s installed on, and if you create an image of an activated machine and drop it onto another system, it will re-register the hardware serial number changes (via the drivers) and realise that it’s been installed on a different system.

Of course, Microsoft needs to be able to protect its software. Piracy of Microsoft products is rampant and while many people find that amusing, no-one denies the company’s right to do something about it. However, it hasn’t worked. At least, it would have worked for Vista had not Microsoft bowed to pressure from OEMs to allow an activation loophole, which was quickly exploited.

Volume Activation 2.0 has not yet been cracked, but now it doesn’t need to be. There’s an official workaround for OEMs and the result is that anyone with a few minutes to spare can download a fully-functional pirated copy of Vista Ultimate (32-bit and 64-bit versions) which needs neither product key nor activation.

So pirates haven’t been slowed down at all, and the rest of us -- the legitimate purchasers -- are left to live with Windows Activation. You really need to ask the question – who’s benefiting here? Certainly not users, and given the amount of discontent this is likely to cause, arguably not Microsoft either.

In its attempts to combat piracy, Microsoft has created a system which doesn’t focus on the problem correctly. After all, how do you define piracy? At its most basic level, piracy occurs when you install software on a machine when you aren’t licensed to do so. But the Windows Activation model isn’t designed to address this particular problem – as far as Windows Activation is concerned, there’s no difference between someone who tries to image two machines with the same activated version of Windows, and a legitimate user who wants to upgrade their system.

If you buy a retail version of Vista, as long as you’re not breaking the terms of the license, then surely it’s none of Microsoft's business what you do with that software. Legitimate users shouldn’t be monitored and inconvenienced to this extent.

The Solution?

There’s no denying that Windows Activation has a serious image problem. Not only is it inconvenient and cumbersome, but it creates a very strong impression in the user's mind that Microsoft doesn't really want to give you the software you paid for.

There are things going on under the hood which have nothing to do with you and which you’re not privy to, and, as I found out, it will affect you if you make an innocent wrong move such as updating too many device drivers.

Additionally, it has been completely bypassed by pirates, so the one group it’s aimed at is sailing blissfully past in a wonderful world where activation doesn’t exist.

At the very least, Microsoft needs to empower users in relation to activation, by involving them a bit more. Perhaps users could have a way of monitoring their cumulative changes, or maybe there could be some method where you could be informed when installing a device driver that it is contributing to your activation totals.

Ultimately, what annoys users more than anything is having something forced on them, and Windows Activation is absolutely one of those areas which causes a great deal of frustration and outrage.

APC has passed all this feedback back to Microsoft, which, to its credit, is taking the situation very seriously and has Vista developers working on a solution.

Apparently there are changes underway to make the whole experience more user-friendly. We certainly hope so. It’s absolutely in Microsoft’s interest to make those changes as widely known as possible. We’ll post information about that once it’s available.

B-b-but, but, it's soooo purty, and shiny...

[drone]

Oh, come on, you Windows bashers! What normal users would ever take the trouble to update their drivers?

I feel as though I should hand out a minor warning for that last post, but I can't figure out what it means. Thus edzy is innocent by reason of incomprehensibility.

[CrossLOPER]

No more hardware updates. Got it.

[Husar]

That's really kinda shabby, though apparently you can still activate it, just have to call home, which is of course a bit annoying.
