The three or so people who run Windows 10 on Arm might be glad to know that x64 emulation is in preview

For Dev Channel Insiders only at the moment


Microsoft has finally released a preview of 64-bit Intel emulation for Windows 10 on Arm in its latest Dev Channel Insider build.

It has been a while coming, and did not make it in November as previously promised. It is, however, at last here for Dev Channel Windows Insiders running on Arm hardware.

Microsoft would dearly like developers to recompile their apps for Arm (as is happening for Apple's new silicon) and while some, notably Adobe, have heeded the call, there remain a large number of x64 apps that simply don't work on the platform.

It was all so different back in 2017, when Windows 10 on Arm was launched. "The long tail of apps customers needed were dominated by 32-bit-only x86 applications," explained Hari Pulapaka, Microsoft Partner Group Program Manager last night, "so we focused our efforts on building an x86 emulator that could run the broad ecosystem of Windows apps seamlessly."

Far be it from us to point out that that little-used suite of apps, Microsoft Office, has had a 64-bit variant for the best part of a decade. Still, it's good to see the emulation finally make an appearance.

x64 apps can come from the Microsoft Store or be installed independently. As well as the likes of the 64-bit-only Autodesk Sketchbook, Pulapaka noted the apps that currently run as 32-bit, such as Chrome, can now use the 64-bit emulation capability. "These apps," he added in what is no way a dig at the browser's notorious thirst for RAM, "may benefit from having more memory when run as 64-bit emulated apps."

Build 21277 also heralded a possible start of some new features for Microsoft's loyal army of unpaid Dev Channel testers.

Those who wish to can opt to hop onto the RS_PRERELEASE branch of the code, although caution is advised; once the jump is made, there is no going back to the FE_RELEASE branch after the rollback option expires (or another build is received).

Microsoft plans to shift all Dev Channel Insiders over to the new branch in the New Year, where some will get to play with the new toys, such as voice typing, which were yanked back in October.

Other than the branching and the x64 emulation for Arm fans, the build contained the usual raft of fixes, including a number around searching in File Explorer. Support for Unicode Emoji 12.1 and 13.0 has also been added and features already in the Beta Channel's Windows Feature Experience Pack, such as improvements to the touch keyboard and screen snipping can be found. ®

  • IT staffing, recruitment biz settles claims it discriminated against Americans
    Foreign workers favored over US residents because that's what clients wanted, allegedly

    Amtex Systems Incorporated, an IT staffing and recruiting firm based in New York City, has agreed to settle claims it discriminated against American workers because company clients wanted workers with temporary visas.

    The US Department of Justice on Wednesday announced the agreement, which followed from a US citizen filing a discrimination complaint with the DoJ's Civil Rights Division’s Immigrant and Employee Rights Section (IER).

    "IT staffing agencies cannot unlawfully exclude applicants or impose additional burdens because of someone’s citizenship or immigration status," said Assistant Attorney General Kristen Clarke of the Justice Department’s Civil Rights Division, in a statement. "The Civil Rights Division is committed to enforcing the law to ensure that job applicants, including US workers, are protected from unlawful discrimination."

  • Will this be one of the world's first RISC-V laptops?
    A sneak peek at a notebook that could be revealed this year

    Pic As Apple and Qualcomm push for more Arm adoption in the notebook space, we have come across a photo of what could become one of the world's first laptops to use the open-source RISC-V instruction set architecture.

    In an interview with The Register, Calista Redmond, CEO of RISC-V International, signaled we will see a RISC-V laptop revealed sometime this year as the ISA's governing body works to garner more financial and development support from large companies.

    It turns out Philipp Tomsich, chair of RISC-V International's software committee, dangled a photo of what could likely be the laptop in question earlier this month in front of RISC-V Week attendees in Paris.

  • Did ID.me hoodwink Americans with IRS facial-recognition tech, senators ask
    Biz tells us: Won't someone please think of the ... fraud we've stopped

    Democrat senators want the FTC to investigate "evidence of deceptive statements" made by ID.me regarding the facial-recognition technology it controversially built for Uncle Sam.

    ID.me made headlines this year when the IRS said US taxpayers would have to enroll in the startup's facial-recognition system to access their tax records in the future. After a public backlash, the IRS reconsidered its plans, and said taxpayers could choose non-biometric methods to verify their identity with the agency online.

    Just before the IRS controversy, ID.me said it uses one-to-one face comparisons. "Our one-to-one face match is comparable to taking a selfie to unlock a smartphone. ID.me does not use one-to-many facial recognition, which is more complex and problematic. Further, privacy is core to our mission and we do not sell the personal information of our users," it said in January.

  • Meet Wizard Spider, the multimillion-dollar gang behind Conti, Ryuk malware
    Russia-linked crime-as-a-service crew is rich, professional – and investing in R&D

    Analysis Wizard Spider, the Russia-linked crew behind high-profile malware Conti, Ryuk and Trickbot, has grown over the past five years into a multimillion-dollar organization that has built a corporate-like operating model, a year-long study has found.

    In a technical report this week, the folks at Prodaft, which has been tracking the cybercrime gang since 2021, outlined its own findings on Wizard Spider, supplemented by info that leaked about the Conti operation in February after the crooks publicly sided with Russia during the illegal invasion of Ukraine.

    What Prodaft found was a gang sitting on assets worth hundreds of millions of dollars funneled from multiple sophisticated malware variants. Wizard Spider, we're told, runs as a business with a complex network of subgroups and teams that target specific types of software, and has associations with other well-known miscreants, including those behind REvil and Qbot (also known as Qakbot or Pinkslipbot).

  • Supreme Court urged to halt 'unconstitutional' Texas content-no-moderation law
    Everyone's entitled to a viewpoint but what's your viewpoint on what exactly is and isn't a viewpoint?

    A coalition of advocacy groups on Tuesday asked the US Supreme Court to block Texas' social media law HB 20 after the US Fifth Circuit Court of Appeals last week lifted a preliminary injunction that had kept it from taking effect.

    The Lone Star State law, which forbids large social media platforms from moderating content that's "lawful-but-awful," as advocacy group the Center for Democracy and Technology puts it, was approved last September by Governor Greg Abbott (R). It was immediately challenged in court and the judge hearing the case imposed a preliminary injunction, preventing the legislation from being enforced, on the basis that the trade groups opposing it – NetChoice and CCIA – were likely to prevail.

    But that injunction was lifted on appeal. That case continues to be litigated, but thanks to the Fifth Circuit, HB 20 can be enforced even as its constitutionality remains in dispute, hence the coalition's application [PDF] this month to the Supreme Court.
