Windows 10: Happy with Anniversary Update?

Yeah, what of it? Wanna take this outside...


Windows 10 for admins and developers

Two of the best features of Windows 10 Anniversary are aimed at developers and IT administrators. One is Project Centennial, also known as the Desktop App Converter, which allows desktop applications to be packaged like UWP apps, as an alternative to traditional Windows setups. The benefits are:

  1. Applications can optionally be delivered through the Windows Store.
  2. Applications are more isolated from the operating system, thanks to registry and file system redirection, so that even badly behaved applications should not damage Windows or leave detritus behind when uninstalled.

An early example of a Project Centennial application is Evernote, though many more may follow.

The potential here is huge. The arrival of desktop applications in the Windows Store might make it interesting at last, while users benefit from clean install and uninstall and an operating system less prone to decay.

Another significant feature is Bash on Windows, which is an implementation of Ubuntu, without a GUI, running via the new Windows Subsystem for Linux, which redirects system calls. The feature, which is still in preview, is primarily aimed at developers, enabling them to use popular Linux tools and utilities. The subsystem has shared access to the file system, but processes are isolated.

One reason to run Bash on Windows is to avoid the MAXPATH limitation, which limits the length of a directory path to 256 characters. This is not an issue for the NTFS file system, but is a gnarly compatibility problem; if Microsoft removed the limitation, many applications might fail or become insecure. It is a real problem for programming tools born on Unix-like operating systems that use deeply nested directories for organising files.

Long path support promises some relief from MAXPATH agony

It turns out that the Windows 10 Anniversary Update has another solution. A new option found in Group Policy, used for automated configuration of Windows systems, suggests that Long Path support will be allowed for applications that specifically state support for it in their configuration files. This feature alone makes the Anniversary Update attractive for Windows developers, especially those who also work cross-platform.

Recommended despite confusion?

Windows 10 Anniversary Update is not dramatically different from the initial release, but adds polish as well as some useful new features to the operating system. That said, Microsoft has not eliminated the sense that Windows has two personalities, UWP and desktop, leading to both cosmetic and functionality issues at times. The updated Defender is an example – it looks like a desktop application, but hit Settings and UWP-style settings open, with a completely different look and feel.

Microsoft has stepped back from Windows 10 smartphones, removing a key rationale for the UWP. It has also reduced the security inherent in the Windows Runtime developed for Windows 8, allowing its sandbox to be breached by Project Centennial, and stating that a much larger subset of the Windows API will be available in UWP. Windows Tablets have also been undermined by Intel's retreat from its low-power Atom chips. What then is the point of UWP? There are certainly manageability advantages, and a successful Windows App Store is another potential benefit, but it has become a strange platform that can only be explained by its history.

Despite these issues, Windows is moving forward and the Anniversary Update demonstrates real progress from the initial release of Windows 10. The nature of Windows-as-a-service, of course, is that most Windows 10 users will eventually have to upgrade whether or not they wish to. Fortunately, in this case it is no bad thing. ®

  • Talos names eight deadly sins in widely used industrial software
    Entire swaths of gear relies on vulnerability-laden Open Automation Software (OAS)

    A researcher at Cisco's Talos threat intelligence team found eight vulnerabilities in the Open Automation Software (OAS) platform that, if exploited, could enable a bad actor to access a device and run code on a targeted system.

    The OAS platform is widely used by a range of industrial enterprises, essentially facilitating the transfer of data within an IT environment between hardware and software and playing a central role in organizations' industrial Internet of Things (IIoT) efforts. It touches a range of devices, including PLCs and OPCs and IoT devices, as well as custom applications and APIs, databases and edge systems.

    Companies like Volvo, General Dynamics, JBT Aerotech and wind-turbine maker AES are among the users of the OAS platform.

  • Despite global uncertainty, $500m hit doesn't rattle Nvidia execs
    CEO acknowledges impact of war, pandemic but says fundamentals ‘are really good’

    Nvidia is expecting a $500 million hit to its global datacenter and consumer business in the second quarter due to COVID lockdowns in China and Russia's invasion of Ukraine. Despite those and other macroeconomic concerns, executives are still optimistic about future prospects.

    "The full impact and duration of the war in Ukraine and COVID lockdowns in China is difficult to predict. However, the impact of our technology and our market opportunities remain unchanged," said Jensen Huang, Nvidia's CEO and co-founder, during the company's first-quarter earnings call.

    Those two statements might sound a little contradictory, including to some investors, particularly following the stock selloff yesterday after concerns over Russia and China prompted Nvidia to issue lower-than-expected guidance for second-quarter revenue.

  • Another AI supercomputer from HPE: Champollion lands in France
    That's the second in a week following similar system in Munich also aimed at researchers

    HPE is lifting the lid on a new AI supercomputer – the second this week – aimed at building and training larger machine learning models to underpin research.

    Based at HPE's Center of Excellence in Grenoble, France, the new supercomputer is to be named Champollion after the French scholar who made advances in deciphering Egyptian hieroglyphs in the 19th century. It was built in partnership with Nvidia using AMD-based Apollo computer nodes fitted with Nvidia's A100 GPUs.

    Champollion brings together HPC and purpose-built AI technologies to train machine learning models at scale and unlock results faster, HPE said. HPE already provides HPC and AI resources from its Grenoble facilities for customers, and the broader research community to access, and said it plans to provide access to Champollion for scientists and engineers globally to accelerate testing of their AI models and research.
