Technology Tales

If it isn’t enough that Vista’s licensing legalese has being causing raised blood pressure, its use of DRM technology is arousing passionate outbursts and outpourings of FUD. The fact that DRM has been part of the Windows has been included in Windows since the 1990’s does nothing to quell the storm. One thing that needs to be pointed out is that the whole furore entails the delivery of protected content to consumers. Microsoft would no doubt approve of the line that if there was no protected content, then there would be no need to worry. However, there is a sizeable number of people who do not trust Microsoft to keep to its word and are making their feelings known.

The embodiment of the issue is Microsoft’s incorporation of HDCP into 64-bit Vista. It is an Intel standard that is on the market, with users already having bad experiences with it. The problems surround the need to ensure that protected video is not intercepted while a movie is being played, and this involves the hardware as much as the software. The result is that you need a compatible monitor that will have the correct inputs so that DRM can be employed. Some also suggest that this is not the end of the matter as regards hardware compatibility and the list can grow long enough that a whole new PC looks like a good idea.

At the heart of this debate is a paper written by Peter Gutmann of the University of Auckland, in which the consequences of Microsoft’s implementation are examined. The idea of a system with an alternative agenda to that which you have is hardly enthralling: neither using CPU time to monitor DRM and the locking down hardware are particularly attractive. Such is the exposure that this article has received that even Microsoft has had to respond to it. The point that they try to make is that decoding of protected content occurs in a sandbox and does not affect anything else that might be going on in the system. Unfortunately for them, many of those adding comments to the piece take the chance to launch a broadside on the company; some of the vitriol is certainly successful when it comes to trying to put me off Vista. To Microsoft’s credit, the negative comments remain, but it far from helps their attempted rebuttal of Gutmann.

Though the main fuel for the negativity is not Gutmann’s paper per se but a lack of trust in Microsoft itself, all of this despite its Trustworthy Computing initiative. The question goes like this: if the company uses DRM for video and audio, where else could it use the technology? The whole licensing debate also furthers this, and it is at this point that the fear, uncertainty and doubt really goes into overdrive, no matter how much effort is expended by people like Ed Bott on debunking any myths. Users generally do not like software taking on itself to decide what can and cannot be done. Personally, I have experience of Word’s habits of this nature in the past, and they were maddening: trying to produce my doctoral thesis with it went OK until I tried pulling the whole thing together using a master document; I backtracked and made PRN files for each chapter so that it wouldn’t change; LaTeX would never have done this….

What is the point of all of this DRM? It looks as if Microsoft clearly feels that it is necessary to pitch the PC as an entertainment content delivery device to continue growing their revenues in the home users market. Some would take this idea even further: that it is control of the entertainment industry that Microsoft wants. However, to do so, they have gone with strong DRM when there exists a growing backlash against the technology. And then there’s the spectre of the technology getting cracked. In fact, Alex Ionescu has found a potential way to fool the Protected Media Path (called Protected Video Path in a ComputerWorld Security article) into working with unsigned device drivers. Needless to say given the furore that has been generated, but there are others who are more than willing to take the idea of cracking Vista DRM even further. A recent remark from a senior Microsoft executive will only encourage this.

I must admit that I remain unconvinced by the premise of using a PC as my only multimedia entertainment device. Having in the past had problems playing DVD’s on my PC, I nowadays stick to using a standalone DVD player to do the honours. And I suspect that I’ll do the same with HD video should I decide to do watch it; it’s not that high on my list of priorities. In fact, I would be happier if Microsoft made a version of Vista with and without protected HD capability, and they do: 32-bit Vista will not play protected HD video. And it avoids all the hackles that have caused so much controversy too, allowing an easier upgrade in the process. The downsides are that the security model isn’t as tough as it is in the 64-bit world and that maximum memory is limited to 4 GB, not an issue right now, it more than likely will become one. If you are keen on Vista, the 32-bit option does give you time to see how the arguments about the 64-bit world run. And if hardware catches up. As for me, I’ll stick with XP for now.

There are things in the Vista EULA that gave me a shock when I first saw them. In fact, one provision set off something of a storm across the web in the latter part of 2006. Microsoft in its wisdom went and made everything more explicit and raised cane in doing so. It was their clarification of the one machine, one licence understanding that was at the heart of the whole furore. The new wording made it crystal clear that you were only allowed to move your licence between machines once and once only. After howls of protest, the XP wording reappeared and things calmed down again.

Around the same time, Paul Thurrott published his take on the Vista EULA on his Windows SuperSite. He takes the view that the new EULA only clarified what in the one XP, and that enthusiast PC builders are but a small proportion of the software market. Another interesting point that he makes is that there is no need to license the home user editions of Vista for use in virtual machines because those users would not be doing that kind of thing. The logical conclusion of this argument is that only technical business users and enthusiasts would ever want to do such a thing; I am both. On the same site, Koroush Ghazi of TweakGuides.com offers an alternate view, at Thurrrott’s invitation, from the enthusiast’s side. That view takes note of the restrictions of both the licensing and all the DRM technology that Microsoft has piled into Vista. Another point made is that enthusiasts add a lot to the coffers of both hardware and software producers.

Bit-tech.net got the Microsoft view on the numbers of activations possible with a copy of retail Vista before further action is required. The number comes in at 10, and it seems a little low. However, Vista will differ from XP in that it thankfully will not need reactivation as often. In fact, it will take changing a hard drive and one other component to do it. That’s less stringent than needing reactivation after changing three components from a wider list in a set period, like it is in XP. While I cannot remember the exact duration of the period in question, 60 days seems to ring a bell.

OEM Vista is more restrictive than this: one reactivation and no more. I learned that from the current issue of PC Plus, the trigger of my concern regarding Windows licensing. Nevertheless, so long as no hard drive changes go on, you should be fine. That said, I do wonder what happens if you add or remove an external hard drive. On this basis at least, it seems OEM is not such a bargain then and Microsoft will not support you anyway.

However, there are cracks appearing in the whole licensing edifice and the whole thing is beginning to look a bit of a mess. Brian Livingston of Windows Secrets has pointed out that you could do a clean installation using only the upgrade edition(s) of Vista by installing it twice. The Vista upgrade will upgrade over itself, allowing you access to the activation process. Of course, he recommends that you only do this when you are in already in possession of an XP licence, and it does mean that your XP licence isn’t put out of its misery, apparently a surprising consequence of the upgrade process if I have understood it correctly.

However, this is not all. Jeff Atwood has shared on his blog Coding Horror that the 30 grace activation period can be extended in three increments to 120 days. Another revelation was that all Windows editions are on the DVD, and it is only the licence key that you have in your possession that will determine the version that you install. In fact, you can install any version for 30 days without entering a licence key at all. Therefore, you can experience 32-bit or 64-bit versions and any edition from Home Basic, Home Premium, Business or Ultimate. The only catch is that once the grace period is up, you have to license the version that is installed at that time.

There is no cracking required for any of the above (a quick Google search digs loads of references to cracking of the Windows activation process). Though it sounds surprising, it is none other than Microsoft itself who has made these possibilities available, albeit in an undocumented fashion. And the reason is not commercial benevolence but the need to keep their technical support costs under control, apparently.

That said, an unintended consequence of the activation period extensibility is that PC hardware enthusiasts, the types who rebuild their machines every few months (in contrast, I regard my main PC as a workhouse and I have no wish to cause undue disruption to my life with this sort of behaviour but each to their own… anyway, it’s not as if they are doing anyone else any harm), would not ever have to activate their copies of Vista, thus avoiding any issues with the activation limit of 1 or 10: an interesting workaround for the limitations in the first place. And all of this is available without (illegally, no doubt) using a fake Windows activation server, as has been reported.

With all of these back doors inserted into the activation process by Microsoft itself, it makes some of the more scary provisions look not only over the top but also plain silly: a bit like using a sledgehammer to crack a nut. For instance, there is a provision that Microsoft could kill your Windows licence if it deems that you breached the terms of that licence. It looks as if it’s meant to cover the loss in functionality at the end of the activation grace period, but it does rather give the appearance that your £370 Vista Ultimate is as ephemeral as a puff of smoke: overdoing that reminder is an almost guaranteed method of encouraging power users jump ship to Linux or another UNIX. And the idea of Windows Genuine Advantage continually phoning home doesn’t provide any great reassurance either. However, it does seem that Microsoft has reactivated XP licences over the phone when reasonable grounds are given: irredeemable loss of system, for example. That ease and cost of technical support returns again. There is a corollary to this: make life easy for Microsoft, and they won’t bother you very much, if at all. Incidentally, if they ever did do a remote control kill of your system, the whole action would be akin to skating on legal thin ice. And I suspect that they may not like making trouble for themselves.

I think I’ll let the dust settle and stay on my XP planet while in a Vista universe. As it happens, Paul Thurrott has a good article on that subject too.

Windows Vista is only out a week and the incompatibilities are already rolling in. Yesterday, it was iTunes that hit the headlines, with Apple making an announcement on its website. More importantly for the likes of me, dues to its effects on my work, SAS has announced that Vista compatibility will not be assured until it launches SAS 9.2. This is not exactly a surprise because they have been advising against using Internet Explorer 7 with their products as they have not carried out their validation. Given that this company is cautious about operating system support anyway, it may be that SAS 9.1.3 runs on Vista without their having validated it to the standards that a large enterprise user would expect. Now, the BBC’s Robert Peston writes an open letter to Bill Gates in his blog following a lost weekend with a laptop running Vista. His problems were hardware related.

There is one surprising thing about all of this: test versions of Vista have been out since last summer, with OEM ones available since November or thereabouts. Why have other software and hardware vendors not being looking ahead for this sort of thing? SAS’s advice regarding IE7 is in the same vein and even more surprising. Though I realise that there is only so much that can be done with a non-final version or, for that matter, in two months, some forward-thinking surely could have been employed. While I know that full legacy compatibility is a big job, it does look as if someone sat on their laurels. Or else, they are not allowing the release of Vista to upset their development and launch schedules and, given that Microsoft’s offering is evolutionary rather than revolutionary, they might well have a point. I think I’ll sit on the fence for a while longer…
