MS tips its hand on WinXP protection system

Suddenly, the builds got a lot less crackable...


Microsoft's adoring public in the unofficial beta distribution channel seems to be awarding null points to the latest escapee from Fort Redmond, WinXP build 2469. This might have something to do with 2469 being seriously harder to crack than previous efforts, but problems with DirectX seem to be turning them off as well.

2469 is the second interim build that's been issued to beta testers since WinXP beta 2, and would have leaked anyway, this being the way of all beta builds that Microsoft releases to external testers. This one however got out a lot faster via a leaked beta tester's ID, which was publiced on IRC channels and which gave an indeterminate number of people download rights from the beta site for seven hours. How many people downloaded, and what they had rights to, is not entirely clear. Microsoft says only a few, to not very much, but we're not too sure about that.

However few leaks there actually are, the next stage in the process is for the code to be passed around in ever-widening circles, and for the protection to be cracked - up until 2469, the latter took place in approximately 24-48 hours. But not this time around.

Microsoft, as we've noted in the past, didn't exactly stretch itself when devising the protection on the earlier builds, and although you were supposed to activate them within 14 days in order to keep running them, cracks and working keys circulated via IRC and published on a few web sites meant that anyone who had illicit code could easily get around that.

The importance of 2469 would therefore seem to us to be that it's the first build where Microsoft has given us some indication of how tough the protection in the shipping product will be. So this might be Product Activation, Release Candidate 1. According to Joolz of MSWinXP.net (which is currently running a Verdict on 2469 piece), the problem lies in something Microsoft's done to winlogon.exe. "The old crack was to replace that file with an older version. This no longer works. It blue screens during setup if you do that! Its winlogon.exe that handles the activation."

It's therefore taking the crackers longer to figure out how to get round this, and as 2469 is substantially less popular than 2465 (big negative is that the broken DirectX means you can't play movies full screen in Media Player), maybe they'll never bother.

The pull of RC1, which is due next month, will likely encourage them to redouble their efforts, if they haven't got around the new system before then, but then you have to wonder how many more shots Microsoft has in its locker.

Undoubtedly whatever protects WinXP when it ships will be cracked, but if protection systems get cracked beforehand, then surely Microsoft will be using tougher ones for the shipping code. So although the crackers aren't part of the beta, in a funny sort of way, they are, when it comes to protection. ®

  • New audio server Pipewire coming to next version of Ubuntu
    What does that mean? Better latency and a replacement for PulseAudio

    The next release of Ubuntu, version 22.10 and codenamed Kinetic Kudu, will switch audio servers to the relatively new PipeWire.

    Don't panic. As J M Barrie said: "All of this has happened before, and it will all happen again." Fedora switched to PipeWire in version 34, over a year ago now. Users who aren't pro-level creators or editors of sound and music on Ubuntu may not notice the planned change.

    Currently, most editions of Ubuntu use the PulseAudio server, which it adopted in version 8.04 Hardy Heron, the company's second LTS release. (The Ubuntu Studio edition uses JACK instead.) Fedora 8 also switched to PulseAudio. Before PulseAudio became the standard, many distros used ESD, the Enlightened Sound Daemon, which came out of the Enlightenment project, best known for its desktop.

  • VMware claims 'bare-metal' performance on virtualized GPUs
    Is... is that why Broadcom wants to buy it?

    The future of high-performance computing will be virtualized, VMware's Uday Kurkure has told The Register.

    Kurkure, the lead engineer for VMware's performance engineering team, has spent the past five years working on ways to virtualize machine-learning workloads running on accelerators. Earlier this month his team reported "near or better than bare-metal performance" for Bidirectional Encoder Representations from Transformers (BERT) and Mask R-CNN — two popular machine-learning workloads — running on virtualized GPUs (vGPU) connected using Nvidia's NVLink interconnect.

    NVLink enables compute and memory resources to be shared across up to four GPUs over a high-bandwidth mesh fabric operating at 6.25GB/s per lane compared to PCIe 4.0's 2.5GB/s. The interconnect enabled Kurkure's team to pool 160GB of GPU memory from the Dell PowerEdge system's four 40GB Nvidia A100 SXM GPUs.

  • Nvidia promises annual updates across CPU, GPU, and DPU lines
    Arm one year, x86 the next, and always faster than a certain chip shop that still can't ship even one standalone GPU

    Computex Nvidia's push deeper into enterprise computing will see its practice of introducing a new GPU architecture every two years brought to its CPUs and data processing units (DPUs, aka SmartNICs).

    Speaking on the company's pre-recorded keynote released to coincide with the Computex exhibition in Taiwan this week, senior vice president for hardware engineering Brian Kelleher spoke of the company's "reputation for unmatched execution on silicon." That's language that needs to be considered in the context of Intel, an Nvidia rival, again delaying a planned entry to the discrete GPU market.

    "We will extend our execution excellence and give each of our chip architectures a two-year rhythm," Kelleher added.

  • Amazon puts 'creepy' AI cameras in UK delivery vans
    Big Bezos is watching you

    Amazon is reportedly installing AI-powered cameras in delivery vans to keep tabs on its drivers in the UK.

    The technology was first deployed, with numerous errors that reportedly denied drivers' bonuses after malfunctions, in the US. Last year, the internet giant produced a corporate video detailing how the cameras monitor drivers' driving behavior for safety reasons. The same system is now apparently being rolled out to vehicles in the UK. 

    Multiple camera lenses are placed under the front mirror. One is directed at the person behind the wheel, one is facing the road, and two are located on either side to provide a wider view. The cameras are monitored by software built by Netradyne, a computer-vision startup focused on driver safety. This code uses machine-learning algorithms to figure out what's going on in and around the vehicle.

  • AWS puts latest homebrew ‘Graviton 3’ Arm CPU in production
    Just one instance type for now, but cheaper than third-gen Xeons or EPYCs

    Amazon Web Services has made its latest homebrew CPU, the Graviton3, available to rent in its Elastic Compute Cloud (EC2) infrastructure-as-a-service offering.

    The cloud colossus launched Graviton3 at its late 2021 re:Invent conference, revealing that the 55-billion-transistor device includes 64 cores, runs at 2.6GHz clock speed, can address DDR5 RAM and 300GB/sec max memory bandwidth, and employs 256-bit Scalable Vector Extensions.

    The chips were offered as a tech preview to select customers. And on Monday, AWS made them available to all comers in a single instance type named C7g.
