Microsoft has walked away from new data center projects in the US and Europe that would have amounted to a capacity of about 2 gigawatts of electricity, according to TD Cowen analysts, who attributed the pullback to an oversupply of the clusters of computers that power artificial intelligence. From a report: The analysts, who rattled investors with a February note highlighting leases Microsoft had abandoned in the US, said the latest move also reflected the company's choice to forgo some new business from ChatGPT maker OpenAI, which it has backed with some $13 billion. Microsoft and the startup earlier this year said they had altered their multiyear agreement, letting OpenAI use cloud-computing services from other companies, provided Microsoft didn't want the business itself.

Microsoft's retrenchment in the last six months included lease cancellations and deferrals, the TD Cowen analysts said in their latest research note, dated Wednesday. Alphabet's Google had stepped in to grab some leases Microsoft abandoned in Europe, the analysts wrote, while Meta Platforms had scooped up some of the freed capacity in Europe.

The Register's Richard Speed reports: Baffled by the plethora of Outlook options out there? You aren't alone. Microsoft veteran Scott Hanselman posted a list of some more variants that could be used to do the same thing. It's a problem common to several Microsoft products. A file needs to be opened, but which app should be used? Should it be Outlook New, or Outlook (New)? With tongue firmly in cheek, Hanselman listed some more options: Outlook (Zero Sugar), Outlook (Caffeine Free), and so on. Hanselman, Developer Community veep at Microsoft, also included Outlook '95, although to our mind the peak came with the version of Outlook in Office 97. A happier, more trusting time when security was less important.

While users can create multiple Outlook profiles to store email account details and data locations, Hanselman's post on Bluesky highlights an issue facing many users of Microsoft's software: which incarnation of the application to use. Teams users often find themselves presented with a variety of applications -- Microsoft Teams and Microsoft Teams (Personal), for example, can often appear side by side in the system tray. [...]

There is a cautionary tale about what happened when a soft drinks company tried to replace a well-liked product with a "new" version and renamed the previous preferred version as "classic." The list posted by Hanselman -- who is also notable for tips on managing Microsoft's personal information manager -- is amusing, but also highlights the perils of having multiple, similarly functioning options to do the same thing, and the potential for confusing users.

Microsoft is expanding its Security Copilot platform with six new AI agents designed to autonomously assist cybersecurity teams by handling tasks like phishing alerts, data loss incidents, and vulnerability monitoring. There are also five third-party AI agents created by its partners, including OneTrust and Tanium. The Verge reports: Microsoft's six security agents will be available in preview next month, and are designed to do things like triage and process phishing and data loss alerts, prioritize critical incidents, and monitor for vulnerabilities. "The six Microsoft Security Copilot agents enable teams to autonomously handle high-volume security and IT tasks while seamlessly integrating with Microsoft Security solutions," says Vasu Jakkal, corporate vice president of Microsoft Security.

Microsoft is also working with OneTrust, Aviatrix, BlueVoyant, Tanium, and Fletch to enable some third-party security agents. These extensions will make it easier to analyze data breaches with OneTrust or perform root cause analysis of network outages and failures with Aviatrix. [...] While these latest AI agents in the Security Copilot are designed for security teams to take advantage of, Microsoft is also improving its phishing protection in Microsoft Teams. Microsoft Defender for Office 365 will start protecting Teams users against phishing and other cyberthreats within Teams next month, including better protection against malicious URLs and attachments.

This week the "Old Vintage Computing Research" blog published a 21,000-word exploration of the DEC PDP-11, the 16-bit minicomputer sold by Digital Equipment Corporation. Slashdot reader AndrewZX calls the blog post "an excellent deep dive" into the machine's history and capabilities "and the classic Venix UNIX that it ran." The blogger still owns a working 1984 DEC Professional 380, "a tank of a machine, a reasonably powerful workstation, and the most practical PDP-adjacent thing you can actually slap on a (large) desk."

But more importantly, "It runs PRO/VENIX, the only official DEC Unix option for the Pros." In that specific market it was almost certainly the earliest such licensed Unix (in 1983) and primarily competed against XENIX, Microsoft's dominant "small Unix," which first emerged for XT-class systems as SCO XENIX in 1984. You'd wonder how rogue processes could be prevented from stomping on each other in such systems when neither the Intel 8086/8088 nor the IBM PC nor the PC/XT had a memory management unit, and the answer was not to try and just hope for the best. It was for this reason that IBM's own Unix variant PC/IX, developed by Interactive Systems Corporation under contract as their intended AT&T killer, was multitasking but single-user since in such an architecture there could be no meaningful security guarantees...

One of Venix's interesting little idiosyncrasies, seen in all three Pro versions, was the SUPER> prompt when you've logged on as root (there is also a MAINT> prompt when you're single-user...

Although Bill Gates had been their biggest nemesis early on, most of the little Unices that flourished in the 1980s and early 90s met their collective demise at the hands of another man: Linus Torvalds. The proliferation of free Unix alternatives like Linux on commodity PC hardware caused the bottom to fall out of the commercial Unix market.
The blogger even found a 1989 log for the computer's one and only guest login session — which seems to consist entirely of someone named tom trying to exit vi.

But the most touching part of the article comes when the author discovers a file named /thankyou that they're certain didn't come with the original Venix. It's an ASCII drawing of a smiling face, under the words "THANK YOU FOR RESCUING ME".

"It's among the last files created on the system before it came into my possession..."

It's all a fun look back to a time when advances in semiconductor density meant microcomputers could do nearly as much as the more expensive minicomputers (while taking up less space) — leaving corporations pondering the new world that was coming: As far back as 1974, an internal skunkworks unit had presented management with two small systems prototypes described as a PDP-8 in a VT50 terminal and a portable PDP-11 chassis.

Engineers were intrigued but sales staff felt these smaller versions would cut into their traditional product lines, and [DEC president Ken] Olsen duly cancelled the project, famously observing no one would want a computer in their home.

Microsoft has begun urging Windows 10 users to upgrade their systems ahead of the October 14, 2025 support deadline, but with a solution many find impractical: just buy a new computer. According to StatCounter data, 58.7% of Windows users remain on Windows 10 despite the impending end of security updates and technical assistance.

In emails to Windows 10 users, Microsoft's primary recommendation is to trade in old devices for newer Windows 11-compatible hardware, rather than focusing on alternative solutions.

A new AI system called Aardvark could deliver weather forecasts as accurate as those from advanced public weather services but run on desktop computers, according to a project unveiled Thursday and published in Nature. Developed by the UK's Alan Turing Institute with partners including Cambridge University, the European Centre for Medium-Range Weather Forecasts and Microsoft, Aardvark aims to make sophisticated forecasting accessible to countries with fewer resources, particularly in Africa.

The system has already outperformed the US Global Forecast System on many variables in testing. Project leader Richard Turner noted the system is "completely open source" and not planned for commercialization by Microsoft.

Microsoft is developing a new Windows 11 feature that will explain how hardware limitations affect PC performance. The latest preview builds include a hidden FAQ section in system settings that addresses GPU memory, system RAM, and OS version impacts.

The feature, discovered by Windows observer "phantomofearth" in this week's Dev Channel build, requires manual activation. It provides specific recommendations for configurations like low RAM or GPUs with less than 4GB memory, and flags outdated Windows versions.

SourceHut, an open-source-friendly git-hosting service, says web crawlers for AI companies are slowing down services through their excessive demands for data. From a report: "SourceHut continues to face disruptions due to aggressive LLM crawlers," the biz reported Monday on its status page. "We are continuously working to deploy mitigations. We have deployed a number of mitigations which are keeping the problem contained for now. However, some of our mitigations may impact end-users."

SourceHut said it had deployed Nepenthes, a tar pit to catch web crawlers that scrape data primarily for training large language models, and noted that doing so might degrade access to some web pages for users. "We have unilaterally blocked several cloud providers, including GCP [Google Cloud] and [Microsoft] Azure, for the high volumes of bot traffic originating from their networks," the biz said, advising administrators of services that integrate with SourceHut to get in touch to arrange an exception to the blocking.

Nature: A Microsoft researcher [this week] presented results behind the company's controversial claim last month to have created the first 'topological' qubits -- a long-sought goal of quantum computing. In front of a packed room at a meeting of the American Physical Society (APS), Chetan Nayak, a theoretical physicist leading Microsoft's quantum computing effort in Redmond, Washington, explained how the company is developing topological qubits, which would be the building blocks for a noise-resistant quantum computer.

Physicists in the audience told Nature's news team they are still unsure whether Microsoft really has made the first topological qubits, however. "It's a hard problem," says Ali Yazdani, an experimental physicist at Princeton University in New Jersey. To anyone trying to make topological qubits, he says, "good luck." When Nayak displayed measurement data during his presentation, he acknowledged that a characteristic signal was difficult to see due to electrical noise, prompting Cornell University theorist Eun-Ah Kim to question its robustness. Microsoft says additional details will be available in a forthcoming paper on the arXiv preprint server.

Trend Micro uncovered an eight-year-long spying campaign exploiting a Windows vulnerability involving malicious .LNK shortcut files, which attackers padded with whitespace to conceal commands. Despite being reported to Microsoft in 2023, the company considers it a UI issue rather than a security risk and has not prioritized a fix. The Register reports: The attack method is low-tech but effective, relying on malicious .LNK shortcut files rigged with commands to download malware. While appearing to point to legitimate files or executables, these shortcuts quietly include extra instructions to fetch or unpack and attempt to run malicious payloads. Ordinarily, the shortcut's target and command-line arguments would be clearly visible in Windows, making suspicious commands easy to spot. But Trend's Zero Day Initiative said it observed North Korea-backed crews padding out the command-line arguments with megabytes of whitespace, burying the actual commands deep out of sight in the user interface.

Trend reported this to Microsoft in September last year and estimates that it has been used since 2017. It said it had found nearly 1,000 tampered .LNK files in circulation but estimates the actual number of attacks could have been higher. "This is one of many bugs that the attackers are using, but this is one that is not patched and that's why we reported it as a zero day," Dustin Childs, head of threat awareness at the Zero Day Initiative, told The Register. "We told Microsoft but they consider it a UI issue, not a security issue. So it doesn't meet their bar for servicing as a security update, but it might be fixed in a later OS version, or something along those lines."

After poring over malicious .LNK samples, the security shop said it found the vast majority of these files were from state-sponsored attackers (around 70 percent), used for espionage or information theft, with another 20 percent going after financial gain. Among the state-sponsored crews, 46 percent of attacks came from North Korea, while Russia, Iran, and China each accounted for around 18 percent of the activity.

The Federal Trade Commission has removed over 300 business guidance blogs published during former President Biden's term, including consumer protection information on AI and privacy lawsuits against Amazon and Microsoft, WIRED reported Tuesday, citing current and former FTC employees.

Deleted posts included guidance about Amazon's alleged use of Ring camera data to train algorithms, Microsoft's $20 million settlement over Xbox children's data collection, and compliance standards for AI chatbots. New FTC Chair Andrew Ferguson has pledged to pursue tech companies but with focus on alleged conservative censorship rather than data collection practices.

Huawei will no longer be able to produce or sell Windows-based PCs as Microsoft's supply license to the Chinese tech company expires this month, according to Chinese tech site MyDrivers. The restriction comes as Huawei remains on the U.S. Department of Commerce's Entity List, requiring American companies to obtain special export licenses to conduct business with the firm.

Richard Yu, executive director of Huawei's consumer business unit, said the company is preparing to pivot to alternative operating systems. Huawei had previously announced plans to abandon Windows for future PC generations. The Chinese tech giant will introduce a new "AI PC" laptop in April running its own Kunpeng CPU and HarmonyOS, alongside a MateBook D16 Linux Edition, its first Linux-based laptop.

An anonymous reader shares a report: Xbox 360 modders have discovered a new way to get homebrew apps and games running on the console. A new software-only exploit known as BadUpdate allows you to use a USB key to hack past Microsoft's Hypervisor protections and run unsigned code and games.

Modern Vintage Gamer has tested BadUpdate and found that you don't even have to open up your Xbox 360 console to get it running. Unlike the RGH or JTAG exploits for the Xbox 360, this BadUpdate method just requires a USB key. If you have the time and patience to get this running successfully, you'll be able to run the Xbox 360 homebrew store which includes games, apps, emulators, utilities, and even custom dashboards.

Tuesday Microsoft "surprised everyone," writes Neowin, "by announcing a new change that will radically improve TypeScript performance" — porting TypeScript to Go.

InfoWorld writes that "The initiative promises dramatic improvements in editor startup speed, build times, and memory usage, making it easier to scale TypeScript to large code bases, Microsoft said." Microsoft's TypeScript team expects to be able to preview command-line type-checking in Go-based tsc by mid-2025, and to deliver a feature-complete Go implementation of TypeScript by the end of the year. [You can build and run the Go code now from Microsoft's new working repository.] Developers who use Go-based TypeScript in the Visual Studio Code editor will feel the increased speed in the editor, Microsoft said. The company promises an 8x improvement in project load times, instant comprehensive error listings across entire projects, and greater responsiveness for all language service operations including completion lists, quick information, go to definition, and find all references. The new TypeScript will also support more advanced refactoring and deeper insights that were previously too expensive to compute, the company said.
Microsoft believes native Go implementations reduce build times by up to 10x, notes Neowin. But "Developers can expect TypeScript 6.0 to have some deprecations and breaking changes to support the upcoming Go-based version." Later this year, Microsoft will be releasing this new native Go implementation as TypeScript 7.0. The current JS-based TypeScript codebase will continue development into the 6.x series until TypeScript 7+ reaches sufficient maturity and adoption, since some projects may depend on certain API features, legacy configurations, or other things that are not supported by TypeScript 7+.
TypeScript's original creator Anders Hejlsberg recorded an announcement video — and also shared his thoughts in a GitHub discussion titled simply... "Why Go?" The TypeScript compiler's move to Go was influenced by specific technical requirements, such as the need for structural compatibility with the existing JavaScript-based codebase, ease of memory management, and the ability to handle complex graph processing efficiently. After evaluating numerous languages and making multiple prototypes — including in C# — Go emerged as the optimal choice...

Let's be real. Microsoft using Go to write a compiler for TypeScript wouldn't have been possible or conceivable in years past. However, over the last few decades, we've seen Microsoft's strong and ongoing commitment to open-source software, prioritizing developer productivity and community collaboration above all. Our goal is to empower developers with the best tools available, unencumbered by internal politics or narrow constraints. This freedom to choose the right tool for each specific job ultimately benefits the entire developer community, driving innovation, efficiency, and improved outcomes. And you can't argue with a 10x outcome!
Hejlsberg also addressed their choice of Go in an online interview with the Michigan TypeScript meetup.

With Microsoft ending free security updates for Windows 10 in October, millions of PCs that don't meet Windows 11's hardware requirements face an uncertain fate... Charities that refurbish and distribute computers to low-income individuals must choose between providing soon-to-be-insecure Windows 10 machines, transitioning to Linux -- despite usability challenges for non-tech-savvy users -- or recycling the hardware, contributing to ewaste. Tom's Hardware reports: So how bad will it really be to run an end-of-lifed Windows 10? Should people worry? [Chester Wisniewski, who serves as Director and Global Field CISO for Sophos, a major security services company] and other experts I talked to are unequivocal. You're at risk. "To put this in perspective, today [the day we talked] was Patch Tuesday," he said. "There were 57 vulnerabilities, 6 of which have already been abused by criminals before the fixes were available. There were also 57 in February and 159 in January. Windows 10 and Windows 11 largely have a shared codebase, meaning most, if not all, vulnerabilities each month are exploitable on both OSs. These will be actively turned into digital weapons by criminals and nation-states alike and Windows 10 users will be somewhat defenseless against them."

So, in short, even though Windows 10 has been around since 2015, there are still massive security holes being patched. Even within the past few weeks, dozens of vulnerabilities were fixed by Microsoft. So what's a charity to do when these updates are running out and clients will be left vulnerable? "What we decided to do is one year ahead of the cutoff, we discontinued Windows 10," said Casey Sorensen, CEO of PCs for People, one of the U.S.'s largest non-profit computer refurbishers. "We will distribute Linux laptops that are 6th or 7th gen. If we distribute a Windows laptop, it will be 8th gen or newer." Sorensen said that any PC that's fifth gen or older will be sent to an ewaste recycler.

[...] Sorensen, who founded the company in 1998, told us that he's comfortable giving clients computers that run Linux Mint, a free OS that's based on Ubuntu. The latest version of Mint, version 22.1, will be supported until 2029. "Ten years ago if we distributed Linux, they would be like what is it," he said. But today, he notes that many view their computers as windows to the Internet and, for that, a user-friendly version of Linux is acceptable. Further reading: Is 2025 the Year of the Linux Desktop?

way2trivial shares a report: Microsoft is testing AI-powered summaries in Notepad. In an update rolling out to Windows Insiders in the Canary and Dev channels, you'll be able to summarize information in Notepad by highlighting a chunk of text, right-clicking it, and selecting Summarize.

Notepad will then generate a summary of the text, as well as provide an option to change its length. You can also generate summaries by selecting text and using the Ctrl + M shortcut or choosing Summarize from the Copilot menu.

Major technology companies are heavily promoting AI agents as transformative tools for work, but industry insiders say no one can agree on what these systems actually are, according to TechCrunch. OpenAI CEO Sam Altman said agents will "join the workforce" this year, while Microsoft CEO Satya Nadella predicted they will replace certain knowledge work. Salesforce CEO Marc Benioff declared his company's goal to become "the number one provider of digital labor in the world."

The definition problem has worsened recently. OpenAI published a blog post defining agents as "automated systems that can independently accomplish tasks," but its developer documentation described them as "LLMs equipped with instructions and tools." Microsoft distinguishes between agents and AI assistants, while Salesforce lists six different categories of agents. "I think that our industry overuses the term 'agent' to the point where it is almost nonsensical," Ryan Salva, senior director of product at Google, told TechCrunch. Andrew Ng, founder of DeepLearning.ai, blamed marketing: "The concepts of AI 'agents' and 'agentic' workflows used to have a technical meaning, but about a year ago, marketers and a few big companies got a hold of them." Analysts say this ambiguity threatens to create misaligned expectations as companies build product lineups around agents.

OpenAI has warned the U.S. government that restricting AI models from learning from copyrighted material would threaten America's technological leadership against China, according to a proposal submitted [PDF] to the Office of Science and Technology Policy for the AI Action Plan.

In its March 13 document, OpenAI argues its AI training aligns with fair use doctrine, saying its models don't replicate works but extract "patterns, linguistic structures, and contextual insights" without harming commercial value of original content. "If the PRC's developers have unfettered access to data and American companies are left without fair use access, the race for AI is effectively over. America loses, as does the success of democratic AI," OpenAI stated.

The Microsoft-backed startup criticized European and UK approaches that allow copyright holders to opt out of AI training, claiming these restrictions hinder innovation, particularly for smaller companies with limited resources. The proposal comes as China-based DeepSeek recently released an AI model with capabilities comparable to American systems despite development at a fraction of the cost.

Microsoft says that some USB printers will start printing random text after installing Windows updates released since late January 2025. From a report: The known issue affects Windows 10 (version 22H2) and Windows 11 (versions 22H2 and 23H2), but according to an update to the Windows release health dashboard, the latest Windows 11 24H2 is not impacted.

"After installing the January 2025 Windows preview update (KB5050092), released January 29, 2025, or later updates, you might observe issues with USB connected dual-mode printers that support both USB Print and IPP Over USB protocols," Redmond explains. "You might observe that the printer unexpectedly prints random text and data, including network commands and unusual characters."

On affected systems, users will often see erroneously printed text that begins with the header "POST /ipp/print HTTP/1.1," followed by other IPP (Internet Printing Protocol) related issues headers. These printing issues are more frequent when the printer is turned on or reconnected after being disconnected. Affected users will observe the printer unexpectedly printing when the print spooler sends IPP protocol messages to the printer and the printer driver is installed on the Windows device.

Mozilla has warned that the U.S. Department of Justice's proposed remedies in its antitrust case against Google would harm independent browsers and reduce competition in the browser market. The DOJ and several state attorneys general last week filed revised proposed remedies in the U.S. v. Google search case that would prohibit all search payments to browser developers, a move Mozilla says would disproportionately impact smaller players.

"These proposed remedies prohibiting search payments to small and independent browsers miss the bigger picture -- and the people who will suffer most are everyday internet users," said Mark Surman, President of Mozilla. Unlike Apple and Microsoft, which generate revenue from hardware and operating systems, Mozilla relies primarily on search revenue to fund browser development. Mozilla argues that cutting these payments would not solve search dominance but would instead strengthen the position of tech giants.

Mozilla also warned that the proposal threatens its ability to maintain Gecko, one of only three major browser engines alongside Google's Chromium and Apple's WebKit. "If we lose our ability to maintain Gecko, it's game over for an open, independent web," Surman said, noting that even Microsoft abandoned its browser engine in 2019. "If Mozilla is unable to sustain our browser engine, it would severely impact browser engine competition and mean the death of the open web as we know it -- essentially, creating a web where dominant players like Google and Apple, have even more control, not less."

Firefox serves 27 million monthly active users in the U.S. and nearly 205 million globally.
