  • Microsoft Flips Windows Backup On By Default Outside the EU
    by BeauHD on 07/07/2026 at 10:00 pm

    Microsoft will turn on Windows settings backup and restore by default for eligible Windows 11 business devices outside the EU, starting with Windows 11 26H2. The Register reports: Now dubbed "Windows settings backup and restore," the service backs up a device's settings and a list of installed Microsoft Store apps, which can then be restored to a new device. Microsoft gave a use case for the technology: "Imagine a lost laptop, a hardware refresh, or an unexpected reset. These are some of the moments when your users need backup most. And that's rarely when anyone wants to discover that backup was never turned on." However, some organizations might not want it on. Perhaps those with strict privacy or data sovereignty requirements, or those regulated by the EU Digital Markets Act (DMA), for whom the default-on behavior won't apply. Windows 11 25H2 and earlier are also excluded, as is any device with a backup policy that explicitly disables the setting. Everything else running Windows 11 26H1 will get switched on after a feature update, and the same applies to 26H2, currently with Windows Insiders in the Experimental channel. Administrators might reasonably be wary of this being opt-out rather than opt-in. Backups are useful, but Microsoft is clear that this is not a comprehensive backup solution, calling it only "one step in a broader Windows resiliency effort." The implications still need consideration. An opt-out setting that quietly ships settings data off-device is exactly the sort of thing that adds to administrators' workloads rather than lightening them. Read more of this story at Slashdot.

  • Samsung Passes Nvidia To Become Most Profitable Company In the World
    by BeauHD on 07/07/2026 at 9:00 pm

    Samsung's chip division is projected to earn more in 2026 than it made across its previous 40 years in semiconductors, driven by soaring AI-fueled demand for memory and storage. The company's latest quarterly operating profit reportedly topped Nvidia's, making Samsung the world's most profitable tech company for the period. Tom's Hardware reports: Brokerage consensus puts Samsung's full-year 2026 operating profit near 300 trillion won ($196 billion), and its second-quarter figure at about 84.6 trillion won ($55.1 billion). Samsung easily beat the consensus with $58.5 billion when it posted preliminary results on July 7, overtaking Nvidia's most recent quarterly operating profit of $53.54 billion and becoming the most profitable technology company in the world for the period, on the back of AI-driven memory demand. Samsung's DS division booked 53.7 trillion won ($35.1 billion) of the company's 57.2 trillion won in total operating profit during the first quarter of 2026, roughly 94% of the total, which is why the division's projection sits so close to Samsung's full-year consensus. "This year's profit will exceed the cumulative profit generated over the past 40 years since we entered the semiconductor business," Kim Yong-Kwan told staff, scoping the claim to the chip business rather than the wider conglomerate.

  • FCC To End Biden-Era Rule That Forces ISPs To List All Their Fees
    by BeauHD on 07/07/2026 at 8:00 pm

    The FCC plans to roll back broadband label rules that require ISPs to itemize all passthrough fees. Under the proposal, providers could instead list a single "up to" amount for location-based charges. It would also allow ISPs to link to pricing labels rather than display them prominently, while eliminating machine-readable pricing files. Ars Technica reports: ISPs routinely advertise prices much lower than those actually charged to consumers on their monthly bills. One method of raising monthly bill prices above advertised rates is to tack on fees that, ISPs claim, are used to offset charges imposed by local governments. ISPs would be well within their rights to advertise accurate monthly prices and charge those exact prices on monthly bills. But because ISPs rarely do that, the FCC has required them to make specific price disclosures to consumers for the past decade. The Biden-era FCC updated the broadband-label rules to require that ISPs "itemize on the label (PDF) all discretionary monthly fees that the provider passes through to the consumer." The change drew protest from Comcast and other ISPs that complained bitterly about the complexity of listing all the hidden fees they had chosen to charge. Under Chairman Brendan Carr, the Trump FCC has steadily whittled away at requirements imposed under Democrats. An order (PDF) released in draft form last week would eliminate the requirement to itemize passthrough fees and let ISPs list them in a single "up to" amount. The "up to" amount can include both government fees and fees charged by non-government entities such as owners of utility poles. "Rather than continuing to require providers to itemize 'passthrough fees' that can vary by location, we allow providers to display such fees in the aggregate, either as a maximum or 'up to' amount for the total fees applicable in any location where the service plan is offered, or as the exact total of such fees assessed in a particular location," the FCC draft order said. The order to be voted on later this month includes a few other changes that will please ISPs and their lobby groups. ISPs will be allowed to provide links to price labels instead of displaying the full labels prominently on ordering pages and account portals, and will be allowed to stop making the price-label information available in machine-readable spreadsheets. The FCC is also relaxing the requirement that price information be available over the phone. The FCC said the change will "allow phone sales representatives to present label information conversationally, as a summary of key label fields, rather than require verbatim recitation." The changes have been in the works since October 2025, when the FCC issued a Notice of Proposed Rulemaking to let the public submit comments on the proposals. The outcome of that process is the draft order, which will be voted on at the FCC's July 22 meeting and take effect 30 days after it is published in the Federal Register. There are many types of passthrough fees that ISPs will be able to stop listing individually and roll into the "up to" amount. The FCC defined the fees as follows, saying they include just about anything that isn't a tax [...]. Another planned change will eliminate a requirement that providers archive all labels for at least two years after a service plan is no longer available. The Utility Reform Network, an advocacy group, told the FCC that the archived labels provide crucial data about how prices and services change over time, and that machine-readable labels are important for affordability research and information accessibility.

  • China's DeepSeek Developing Its Own AI Chip
    by BeauHD on 07/07/2026 at 7:00 pm

    An anonymous reader quotes a report from Reuters: Chinese startup DeepSeek is developing its own AI chip, according to three people familiar with the matter, a push that could reduce its reliance on Nvidia and Huawei chips, which it has depended on to train and run its globally popular models. The chip is designed for inference -- the stage of AI computing in which a trained model generates responses for users -- rather than for training new models, the sources said. If successful, DeepSeek's expansion into semiconductor development would mark a major strategic shift for a company widely hailed in China as the country's AI champion, potentially adding to challenges faced by Chinese tech giant Huawei.

  • Major Banks In Talks To Exploit Debit Card Loophole
    by BeauHD on 07/07/2026 at 6:00 pm

    JPMorgan, Bank of America, Wells Fargo, PNC, and other major banks have reportedly explored acquiring Fiserv's debit-card networks, STAR and Accel, in a move that could help them bypass federal caps on debit-card transaction fees. A law limits the fees big banks can charge merchants, but only if the transactions are routed through an outside network. There are no caps on these interchange fees over a bank-owned network, however. The Wall Street Journal reports: When Capital One Financial bought Discover Financial in a $50.6 billion deal, it got a network that cut out the need for a middleman in card transactions and allowed it to deal more directly with merchants. Now, big banks are looking on with envy because owning a network can mean exemption from a federal law that caps debit-card fees. Those fees collectively amount to billions of dollars each year across the industry, but banks have long complained the government-defined cap limits their ability to offer customers debit-card rewards and other services. Some have been exploring a small deal that could upend the rules, though they are worried about political backlash if they try. Big banks including JPMorgan Chase, Bank of America, Wells Fargo and PNC Financial Services Group have in recent months held preliminary and tentative discussions about a deal to acquire a network owned by the financial-technology company Fiserv, according to people familiar with the matter. There is no certainty a deal will happen. Several of the banks that looked at the Fiserv network have already decided it would be unlikely for them to move forward, some of the people said. Some have privately expressed concern that such a deal could prompt backlash from lawmakers, regulators and merchants, the people added. Read more of this story at Slashdot.

  • Microsoft Can Track Users Via a Windows Device ID
    by BeauHD on 07/07/2026 at 5:00 pm

    A criminal complaint against alleged Scattered Spider member Peter Stokes revealed that Microsoft can associate Windows activity with a persistent "Global Device ID," which investigators used to link his PC to online activity connected to a hack. While unique device IDs are common, the case has raised privacy concerns because the identifier can apparently persist across updates, has no simple opt-out, and may allow Microsoft to connect a Windows installation to activity on third-party services. PCMag reports: Last week, the U.S. announced it had extradited 19-year-old Peter Stokes from Europe for allegedly being a member of the notorious hacking group Scattered Spider. But the case stands out because Microsoft played a key role in linking Stokes to the suspected hacking crimes, according to an unsealed criminal complaint. Stokes allegedly hacked an unnamed luxury jewelry retailer in May 2025 while using a VPN. The 39-page criminal complaint shows the FBI used Microsoft records to discover that his IP address was associated with a Microsoft device identifier known as Global Device ID (GDID). "According to a Microsoft representative, a Global Device Identifier in the Windows ecosystem is a persistent, device-level identifier designed to uniquely identify an installation of a Windows operating system on a device, either a physical device (e.g., a mobile phone or laptop) or virtual machine, across certain Microsoft services and scenarios," the complaint explains. The global device ID isn't exactly surprising, given that it's standard practice to assign a unique ID to each account or device so a tech provider can recognize and distinguish between them. But the complaint reveals Microsoft can associate the GDID with third-party services and the timing as well, giving Redmond a way to theoretically track a user's online activity. In other words, Redmond might be able to track the online activity of your Windows PC without third-party browser cookies. Stokes was discovered exploiting a web development tool called ngrok to bypass the jewelry retailer's network defenses. The complaint says Microsoft had records showing that on May 12, 2025, at 19:21 UTC, the GDID associated with Stokes' computer "accessed, among other ngrok pages, 'https://dashboard[.]ngrok.com/signup,' the ngrok page to set up an ngrok account." The document adds that Microsoft records also showed the GDID accessing "multiple sites" from servers at Tzulo, a web hosting provider, to help pull off the hack. Hence, the fact that federal investigators used the Microsoft identifier to nab a suspected hacker is raising concerns that it could be abused for other surveillance purposes. "Microsoft Windows is surveillance software," cybersecurity expert Matthew Hickey alleged in a tweet. Read more of this story at Slashdot.
