Open source Windows alternative ReactOS has reached a major milestone: The operating system can now be installed directly onto an NTFS drive partition. As reported by Phoronix, the move to NTFS clears a long-standing hurdle for the project and brings it one step closer to finally reaching beta.
Prior to this latest announcement, ReactOS required users to keep a FAT32 partition for installations. A proprietary Microsoft-developed filesystem, NTFS can trace its roots back through the Windows NT family lineage starting in 1993 with Windows NT 3.1. The variant introduced with Windows XP in 2001 remains the standard used by most Windows systems today. With ReactOS's stated goal of reaching binary compatibility with Windows Server 2003, being confined to FAT32 partitions was a practical barrier to clear on the way to reproducing the Windows environment.
However, users looking to hop off the Windows train shouldn't be grabbing their bags just yet. ReactOS wrote that the new driver still "lacks caching (which causes inferior performance), journaling and security support." So while the new driver is here, even the most intrepid of OS tinkerers should tread carefully. The ReactOS team warned in its announcement on X that there are still "potentially undiscovered bugs."
In its first live event in two years, Microsoft today announced its newest Surface laptop, outlined a host of changes coming to Windows 11, and shared a vision of how local-AI and agentic workflows could reshape personal computing for those in the dev community as well as home enthusiasts.
Originally teased in May 2026, the new Surface Laptop Ultra will be Microsoft's first offering to take advantage of the new Nvidia RTX Spark SoC (system on a chip). The device has a starting price of $2,599 and comes in various SoC and memory configurations, with either a 5120-core or 6144-core Blackwell GPU and up to 128GB of LPDDR5x unified memory. It will begin shipping on October 16 and is available for preorder now.
While the new Ultra is clearly focused on the developer crowd, graphical performance was highlighted during the presentation to show off just how capable the laptop can be. By leaning on unified memory allocation rather than the physical VRAM limits of a traditional GPU, the laptop can assign its resources to handle modern gaming tasks as well as local AI development and deployment. The new Gears of War: E-Day was shown running on the system, meaning that even without a traditional gaming GPU, AAA titles are on the table.
It wasn’t that long ago that ClickFix attacks were exotic. Now the technique has become mainstream as attackers reap its simplicity and effectiveness in infecting users of PCs and Macs alike. All that’s required is a compromised website—a painless enough task—a fake CAPTCHA overlay, and the inclusion of a single terminal command. So many visitors get suckered into pasting and running the command that just about every malware pusher has adopted the technique. Even Kremlin-backed hacking groups are joining in.
“Reddit is becoming post after post after post of people getting their computer infected via ClickFix,” independent researcher Kevin Beaumont observed Thursday. “Legit websites everywhere [are] getting hacked to serve the fake captcha prompts.”
More seasoned Internet users—a fair number who read this site—are quick to dismiss the attack. They typically blame the people who fall for the scams and marvel at their gullibility and lack of attention. The reality is that for more casual users, using computers and the Internet has become so difficult—think impossible-to-close interstitials, CAPTCHAs with an endless series of pictures to analyze, and constantly changing interfaces that bury the features they’re looking for—that they have grown desensitized to instructions that seem ridiculous and burdensome.
A nearly identical exploit kit that targets critical vulnerabilities in both Chromium-based browsers and older versions of Windows is being actively used by at least four hacking groups, some of which have ties to the Chinese government.
Researchers from security firm Proofpoint said Wednesday that BlueMoon, the name they gave to the kit, chains three vulnerabilities together so the attackers using it can install malware of their choice. BlueMoon exploits two Chromium vulnerabilities and one in the kernel of Windows 10 (Oct. 2018 Update), Windows Server 2019, Windows 10 2004, Windows Server 2022, and the initial release of Windows 11. All three vulnerabilities have received patches in the past 24 hours.
The attacks lacked the stealth found in many campaigns. More often, hackers want to exploit newly discovered vulnerabilities sparingly to lengthen their longevity. Proofpoint hypothesized that one reason for the widely used and visible exploit chain was to take advantage of a “patch gap” in the Chromium supply chain, which spans the time a patch is available from developers and the time that patch is incorporated into browsers such as Chrome and Edge. Another likely contributor was the use of AI, which can often spot vulnerabilities faster than discovery performed solely by humans.
On an afternoon in mid-May, dozens of Microsoft engineers and their managers gathered online and in a conference room at the company’s Redmond, Washington, headquarters to discuss Project Glasswing.
The tech giant was racing to fix weaknesses in its code that a new AI model known as Mythos was uncovering at an unprecedented clip. The AI behemoth Anthropic, which developed Mythos, had given access to select organizations that make software used by regular people, companies, and governments across the world. The goal was to find and fix the vulnerabilities before hackers and adversarial governments like China began using similar tools to find and exploit them for espionage and sabotage.
As the group settled in, one engineer asked the question that loomed over the meeting: Did Mythos “live up to the hype that Anthropic claimed it would have had?”
LG is reportedly pulling a McAfee pop-up ad from a controversial app that some of its monitors have stealthily installed on connected computers.
An example of the pop-up ad is seen in a still from Gamers Nexus' video.

The app, LG Monitor App Installer, installs itself through a Windows Update alongside monitor driver updates. LG Monitor App Installer then pushes ads for a 30-day free trial for McAfee, as well as other software, via a pop-up on affected systems, multiple users have reported.
This has drawn negative attention recently, with complaints surfacing on Reddit and a subsequent video from YouTube channel Gamers Nexus. In the video, editor-in-chief Steve Burke said that the publication paid $1,200 for an LG UltraGear 3GX900A-B gaming monitor (the monitor’s price dropped to $600 two days later, Burke said) for testing and replicated the behavior “several times” across “multiple” Windows 11 systems.
For years, Microsoft has leaned heavily into extensive backward compatibility across multiple generations of Xbox hardware as a major selling point for its consoles. Today, that effort expands past the console ecosystem, making select original Xbox titles officially playable (and purchasable) on Windows PCs for the first time.
The appropriately and bluntly named "Xbox Backward Compatibility on PC" program kicks off today with compatibility for BLiNX: The Time Sweeper, Conker: Live and Reloaded, Crimson Skies: High Road to Revenge, and Fuzion Frenzy. PC players can download each title for $10, but those with Xbox Game Pass subscriptions or existing digital licenses for these games on console will have instant access without an additional purchase (no such luck if you simply stick an original Xbox disc in your PC drive, alas).
Playing these older Xbox titles on PC enables some bonus graphical features like Vsync support, anisotropic filtering, enhanced anti-aliasing, and up to 4x resolution scaling of the original SD signal (to 2560x1920). Games are limited to their original frame rates and aspect ratios, though, which means a 30 fps 4:3 image in most cases. Microsoft says this first batch of games should be playable with 11-year-old GTX 950 graphics hardware, but recommends a 2017-era GTX 1070 Ti with 8GB of VRAM for best performance.
Right on the heels of Microsoft releasing a record number of security patches, a researcher has published exploit code that can enable low-privilege Windows accounts to make sensitive changes to administrator accounts.
The exploit, which multiple researchers say works, is sending Microsoft scrambling, yet again, to patch a zero-day released by an anonymous researcher who has complained about the software maker’s handling of their bug reports. To date, the pseudonymous NightmareEclypse has published nine such exploits, including Tuesday’s HiveLegacy. The researcher said the proof-of-concept code included in the report was stripped down to prevent attackers from using it maliciously.
HiveLegacy is an elevation-of-privilege exploit that targets a vulnerability residing in the Windows User Profile Service. It allows users (and with more work likely processes) with limited system rights to compromise an admin user's account by modifying its classes registry hive, a resource that ensures the correct application opens when certain types of files are clicked on in Windows Explorer.
A patch Microsoft released on Wednesday to fix a zero-day vulnerability in its Defender security engine may cause Windows machines to write files large enough to completely consume available disk space, the researcher who discovered the flaw said.
RoguePlanet, tracked as CVE-2026-50656, came to public notice in June when NightmareEclipse, the pseudonymous name used by a researcher, disclosed it along with code for exploiting it. The vulnerability allows remote attackers to gain administrative control of Windows 10 and Windows 11 machines, even when real-time protection has been disabled. Over the past few months, the anonymous researcher has published a handful of other zero-days that have sent Microsoft scrambling to develop patches.
Microsoft said Wednesday that it patched RoguePlanet with an update to the Microsoft Malware Protection Engine, which is used by the Defender antivirus app. The fix will automatically be downloaded and installed without users having to take any action. Wednesday’s update also includes “defense-in-depth updates to help improve security-related features.”
Microsoft ended official support for Windows 10 in 2025, but the company may have a harder time than expected putting the operating system out to pasture. After promising a year of optional extended update support, Microsoft has changed its policy, tacking on another year to its Extended Security Updates (ESU) program. If you are still clinging to Windows 10, you don't have to do anything but enjoy that extra year.
The last regular updates rolled out to Windows 10 in October of last year, but the Internet can be a dangerous place for unpatched Windows machines. That was a problem for Microsoft, as Windows 11 usage had only barely surpassed Windows 10 when support ended. Microsoft's solution was to give everyone on the old OS a free year of extended updates.
That program was set to end on October 12, 2026, but Microsoft has updated its policy with hardly a whisper, pushing back the end of extended updates to October 12, 2027. The ESU support page was updated with that date, and Microsoft's blog post on the program has a new editor's note confirming the change.
Microsoft's Build developer conference kicked off today, and as with almost everything the company has done in the last few years, Microsoft's opening keynote focused overwhelmingly on AI and other closely related technologies. There's Microsoft Scout, an OpenClaw-based "Autopilot" agent that can hook into Microsoft 365 data to perform tasks for users; several new AI models; an expanded preview of "Codename MDASH," which is a "multi-model agentic scanning system" meant to detect and fix software vulnerabilities.
A few of those announcements stood out to us as particularly interesting, either for esoteric technical reasons or because they seem like they may have some utility for those who aren't spending their every waking moment using generative AI tools. (Microsoft's recent efforts to make its flagship operating system faster, more reliable, more useful, and less annoying didn't really come up, but there have been plenty of other announcements on that front lately.)
On the hardware front, we didn't get any updates for existing Surface devices (not counting yesterday's Surface Laptop Ultra announcement), but we did get something new: the Surface RTX Spark Dev Box is "a compact developer PC" built around Nvidia's new RTX Spark chip with up to 128GB of built-in memory.
These days, Nvidia primarily sells AI data center products, and its traditional consumer devices feel like more of a side project. But the company occasionally still releases something designed for consumers. After a couple of years of rumors, Nvidia has announced an Arm-based chip designed to power Windows PCs. Dubbed RTX Spark, the new chip combines a 20-core Nvidia Grace CPU co-developed with MediaTek, up to 6,144 Blackwell-based GPU cores (the same architecture as the RTX 50-series GPUs), and support for up to 128GB of unified LPDDR5x memory.
Nvidia and its partners offered nothing about expected pricing, but both "slim Windows laptops with all-day battery life and premium displays" and "compact desktop PCs" are slated to be "available this fall" from partners including Asus, Dell, HP, Lenovo, Microsoft, MSI, Acer, and Gigabyte.
This isn't Nvidia's first chip for Windows PCs; earlier chips in the Tegra series powered several of the short-lived Windows RT tablets. But Tegra chips largely stopped appearing in consumer devices following the Tegra X1 in the late 2010s (variants power the original Nintendo Switch and the apparently unkillable Nvidia Shield TV box). Modern Arm-based PCs in the Windows 10 and Windows 11 eras have all used processors from Qualcomm.
If you owned a Windows computer in the late '90s or early '00s, you probably remember 3D Pinball for Windows - Space Cadet, a surprisingly competent virtual table included for free with multiple Microsoft OS releases through Windows XP. Despite the game's authenticity to real pinball, Space Cadet wasn't based on an extant physical table, but was merely one part of the Full Tilt! Pinball software collection sold by Maxis starting in 1995.
In the intervening years, hobbyists and enthusiasts have discussed the possibility of crafting a homebrew physical table based on Space Cadet many times, without much tangible progress to show for it. A company called Deeproot Pinball went so far as to develop a reskinned prototype of Space Cadet's layout for a planned 2021 release before the whole company went under amid fraud allegations.
Where Deeproot failed, though, hobbyist CNCDan hopes to succeed in creating a physical Space Cadet table. In a video, he documents the start of his build process, which already includes 3D-printed mechanical flippers, pop bumpers (complete with embedded LEDs), slingshots, and even a raised playfield, all designed to mimic the look and feel of the original Windows table.
When Windows 11 launched in 2021, we mostly liked its refreshed look—the rounded corners and menus with just a hint of translucency were a nice change from the flat colors and hard corners of the Windows 8/10 era. But its reformulated taskbar and Start menu came with a number of functional regressions from the versions in Windows 10. Some of these were addressed quickly; others continue to linger.
A new Windows Insider Preview build released to testers includes a new wave of improvements that fix longstanding regressions while trying out new things.
Most significantly, the Windows 11 taskbar can now be docked to any edge of your screen, including the left and right, something that was possible in Windows 10 (and many older versions of Windows) but has been missing from Windows 11 since launch. Users can configure slightly different taskbar behavior for every taskbar position—if you prefer a different icon alignment or a left/right-mounted taskbar over a top/bottom-mounted taskbar, or if you want different settings for labels and icon groupings, you can choose different options for each position and Windows will remember them.
Hardware driver updates can be a blessing and a curse. When they're good, they can fix bugs, improve performance, and add new capabilities, giving your PC a minor upgrade without requiring any extra effort or investment. When they're bad, they can make a once-reliable PC slower and unstable, handing you a one-way ticket to blue screen town (or whatever color the Windows error screen is these days).
While gamers and other enthusiasts may be in the habit of downloading and installing new driver updates for their systems, most PC users just let Windows Update handle driver installation and updates. PC manufacturers can submit their own tested and validated versions of drivers for distribution via Windows Update, which (at least in theory) should maximize stability and minimize problems.
But mistakes happen, and sometimes a driver update is distributed that causes more problems than it fixes. Normally when this happens, the company either needs to submit an updated fixed driver to Windows Update, or the user is on the hook for either rolling back the update or finding and downloading a better driver themselves.
Microsoft has heard your complaints about Windows 11, and it wants to make things better. That has been the messaging out of Microsoft for most of this year, and the company is also going out of its way to make sure that people know what is being improved and how.
One of the goals on Microsoft’s long list was to improve the performance of core Windows components like the Start menu and File Explorer. One of the strategies for making this happen is something Microsoft is calling the “low latency profile,” which will speed things up by calling on an extra burst of CPU speed when users open Start or other apps and context menus.
Windows Central has tested the low latency profile available in test builds of Windows 11 and observed a noticeable increase in speed and responsiveness on the same hardware compared to the current public version of Windows 11 25H2.
Valve and its SteamOS operating system have already done what a bunch of companies (including Apple) have been trying to do for decades: make a dent in Windows’ dominance in PC gaming.
I mean, sure, according to Valve’s own statistics, Microsoft remains dominant. Over 92 percent of PCs in the Steam Hardware Survey run some version of Windows. But five years ago, this number was just over 96 percent. Ten years ago, it was just under 96 percent. Fifteen years ago? It was 96 percent. Go back any further than that and Steam only runs on Windows in the first place, itself a testament to Microsoft's ubiquity.
Between April 2021 and now, Linux’s share has climbed from under 1 percent to over 5 percent. This is a small number, and it's not all SteamOS (Valve's OS isn't broken out, but Arch, the base distribution for SteamOS, accounts for about 0.33 of that just-over-5-percent). But it’s also more than these numbers have ever moved. By making Windows games run on Linux, rather than trying to push game developers to make Linux-native ports, Valve has done via organic word-of-mouth success what the company utterly failed to do in the early 2010s when it tried to take on Windows directly.
Microsoft released an emergency patch for its ASP.NET Core to fix a high-severity vulnerability that allows unauthenticated attackers to gain SYSTEM privileges on devices that use the Web development framework to run Linux or macOS apps.
The software maker said Tuesday evening that the vulnerability, tracked as CVE-2026-40372, affects versions 10.0.0 through 10.0.6 of the Microsoft.AspNetCore.DataProtection NuGet, a package that’s part of the framework. The critical flaw stems from a faulty verification of cryptographic signatures. It can be exploited to allow unauthenticated attackers to forge authentication payloads during the HMAC validation process, which is used to verify the integrity and authenticity of data exchanged between a client and a server.
During the time users ran a vulnerable version of the package, they were left open to an attack that would allow unauthenticated people to gain sensitive SYSTEM privileges that would allow full compromise of the underlying machine. Even after the vulnerability is patched, devices may still be compromised if authentication credentials created by a threat actor aren’t purged.
Two years ago, Microsoft launched its first wave of “Copilot+” Windows PCs with a handful of exclusive features that could take advantage of the neural processing unit (NPU) hardware being built into newer laptop processors. These NPUs could enable AI and machine learning features that could run locally rather than in someone’s cloud, theoretically enhancing security and privacy.
One of the first Copilot+ features was Recall, a feature that promised to track all your PC usage via screenshot to help you remember your past activity. But as originally implemented, Recall was neither private nor secure; the feature stored its screenshots plus a giant database of all user activity in totally unencrypted files on the user’s disk, making it trivial for anyone with remote or local access to grab days, weeks, or even months of sensitive data, depending on the age of the user’s Recall database.
After journalists and security researchers discovered and detailed these flaws, Microsoft delayed the Recall rollout by almost a year and substantially overhauled its security. All locally stored data would now be encrypted and viewable only with Windows Hello authentication; the feature now did a better job detecting and excluding sensitive information, including financial information, from its database; and Recall would be turned off by default, rather than enabled on every PC that supported it.
Most people access Google's search and AI products through a browser, but you've got some new options today. Google has been testing a Windows search app for some months, and it's now officially available. Over on the Apple side of the fence, Google has focused its efforts on designing a native Gemini app. That one is also available widely today with the same features you get in the Gemini web interface.
The "Google app for desktop" first arrived on Windows in a beta form last September. It was pretty rough at first, and Google couldn't even update the app's early versions, forcing users to uninstall and reinstall new builds. That won't be a concern with the official release, which brings assorted search capabilities to your Windows PC.
The Google app can search the web or your PC.

You can open the Google app by pressing Alt + Space at any time. The compact search UI floats on top of whatever you're doing, allowing you to instantly search the web and (with authorization) your local files and apps. Web results look like what you'd get in a browser, right down to the inclusion of AI Overviews and AI Mode.
Microsoft says it hears the complaints people have about the current state of Windows, and it wants to fix them. One of those fixes is another overhaul for its Windows Insider Program, the public beta system that Microsoft has used since Windows 10 to test and preview upcoming versions of the operating system and new app updates.
The company hinted at this in its "commitment to Windows quality" post last month, and it's announcing details today in another post attributed to Microsoft Principal Group Product Manager Alec Oot.
Since its last reorganization in 2023, the Windows Insider Program has had four testing channels. From least to most stable, these are the Canary channel, the Dev channel, the Beta channel, and the Release Preview channel. Both Canary and Dev are for earlier builds of Windows and new apps, while Beta tends to get things that are closer to finished and much more likely to ship to the general public. The Release Preview channel is a new Windows version's last stop before public release and is usually near-final.
If you were eating in a restaurant and the head chef came out from the back multiple times to loudly proclaim that the kitchen was deeply committed to the quality of the food, would you find that reassuring? Or would you start wondering why the chef felt the need to keep saying it?
That's the conundrum facing the Windows team at Microsoft right now. Windows VP Pavan Davuluri has gone on the record several times since the start of the year to insist that Microsoft is committed to Windows 11's quality, most recently in a post today titled "our commitment to Windows quality." Windows 11 is an operating system that many people use but that few enthusiasts seem to love, either because of recent high-profile bugs or the steadily increasing flow of annoying add-ons, notifications, "helpful" "reminders," and ads for other Microsoft products and services that coat most of the operating system's virtual surfaces.
"Every day, we hear from the community about how you experience Windows," Davuluri wrote. "And over the past several months, the team and I have spent a great deal of time analyzing your feedback. What came through was the voice of people who care deeply about Windows and want it to be better."
Modern gamers are used to loading up a new game for the first time and being forced to wait multiple minutes while a "compiling shaders" step whirs away, optimizing advanced 3D effects for their specific hardware. This week at the Game Developers Conference, Microsoft provided some updates about its Advanced Shader Delivery for Windows efforts, which are designed to fix the problem by generating collections of precompiled shaders that can be downloaded ahead of time.
In a console environment, developers can optimize and precompile their graphics shaders to work well with a set driver and GPU environment. On PC, though, developers tend to leave their shaders as uncompiled code that can then be compiled and cached at runtime based on the specific hardware and drivers on the player's machine.
Microsoft's Advanced Shader Delivery infrastructure aims to fix this problem by automating the process of precompiling shaders that work across "a large matrix of drivers and GPUs in the Windows ecosystem," as the company puts it. To enable that, developers use Microsoft's Direct3D API to create a State Object Database (SODB) that represents in-game assets at the game engine level. That asset database is then fed into multiple shader compilers to create a Precompiled Shader Database (PSDB) that supports multiple display adapters from different hardware vendors.
When Asus and Microsoft launched the ROG Xbox Ally X last summer, it came with a bespoke controller-driven full-screen interface running on top of Windows 11. The handheld was still running Windows under the hood, and you could bring up the typical Windows desktop any time, but it defaulted to the full-screen gaming UI.
Then called either the "Xbox Experience for Handheld" or the "Xbox Full-Screen Experience (FSE)," depending on who you asked and when, Microsoft said it would be available on all Windows PCs at some point in 2026. That point has apparently arrived: Microsoft announced this week at the Game Developers Conference that other Windows 11 PCs "in select markets" would be getting what's now being called "Xbox mode" starting in April.
Under the hood, a PC running in Xbox mode is still running regular-old Windows, with the same capabilities as any other PC. But there are system services and UI elements (like the standard Start menu and taskbar) that don't launch when the system is in Xbox mode, something Microsoft claims can save a gigabyte or two of RAM while also allowing systems to use less energy. Users can return to Windows' traditional desktop mode whenever they want, though.
