Whenever Microsoft starts messing with something like the search function in Windows, a lot of people are going to be holding their breath and expecting the worst. Well, get ready, because they're redesigning the whole thing. In July, we shared how we are improving the Windows Search Box with less clutter and more control. We introduced a calmer home screen, removed promotional content from web results, and gave you more choice over whether web and Microsoft Store suggestions appear. Today, we're carrying those investments forward with a new Windows Search experience built on WinUI 3. This modern foundation makes Windows Search faster and more efficient with resources, while delivering an even more streamlined and focused design. ↫ Anshul Rawat at the Windows Blogs The company claims this new version of search is faster and uses less memory, which, if true, are very welcome improvements. It's also just a single column of results now, and they're adding inline previews for things like weather and files on your machine, as well as for answers to all kinds of queries you might normally go to an online search engine for. You can now also use search to perform all kinds of tasks in Windows, like turning on dark mode, managing windows, and so on. All of this can be done using relatively natural language, and Microsoft claims they've implemented better detection of typing errors and synonyms, which is quite welcome. Weirdly enough, though, it's not yet integrated into the Start menu, since it's a preview just for testers, but that's something they're working on for future releases. Judging by the videos and screenshots, I'm actually kind of positively surprised. This looks quite decent and nice, and if the promised performance improvements actually materialise, this may actually be an upgrade to search worth looking forward to. Of course, this is still Microsoft, so it's just as likely they'll screw up somewhere between now and when this goes live to regular users. Still, I think it looks decent.

Chimera Linux is a relatively new Linux distribution, and quite a unique on at that, as it combines the core tools from FreeBSD, the LLVM toolchain, and the Musl C library instead of the usual suspects. Despite being relatively new, it still has some serious pedigree as the project was started by Nina "q66", who was part of the Void Linux team. At Void, she maintained the various PowerPC/POWER ports of the distribution until Chimera became her sole focus. Nina published a detailed blog post today about how the Chimera team builds the tooling for their distribution, as well as the goals it's trying to achieve. It covers everything from a bit of personal history, the rationale behind the project, who it's catering to, how its tooling works and why, and the infrastructure they've built that underpins it all. There's a lot to process here, with one of the most interesting little details - at least to me, as someone who has two POWER9 machines - the fact that Chimera started with the ppc64le target only. The article is an incredibly interesting look at not just the how of Chimera, but also the why, which makes for some really fascinating reading.

KDE contributor and developer Niccolò Venerandi has published an article about COSMIC, System76's brand new desktop environment. It's been almost a year since I've last tried COSMIC; though development since then has mostly been centered around stability (going from late alpha to stable releases now!) there have been a fair bit of user-facing changes too which I adore. I thus have to ask myself: should I switch to COSMIC? The answer obviously is no, but that's just because I got addicted to KDE Plasma, so let's try to be more objective here. ↫ Niccolò Venerandi Honestly, this is one of the best "reviews" I've seen of COSMIC, and paints System76's hard work in a really positive light. Venerandi spots countless really nice touches he'd love to see adopted by KDE, while also hitting on what I agree is COSMIC's biggest shortcoming at this point: there's basically no ecosystem around it. COSMIC uses its own Rust-based toolkit instead of GTK or Qt, but of course, there's very few other applications that actually use said toolkit. The end result is that if you run COSMIC, you're going to have to supplement it with countless GTK and Qt application, none of which will inherit all the nice features, touches, and graphics from COSMIC. This isn't really a complaint about COSMIC itself or the work its developers are putting into it, but more a fact of life for such a new desktop environment using an otherwise unpopular (as of right now) toolkit. This may very well change in the future, but for now, if you choose to run COSMIC, you're going to have to accept a very inconsistent and messy desktop. This won't matter to everyone, but it sure does matter to me, and it's the one reason why at this point I have zero interest in running COSMIC. I really hope this changes in the future - competition is good - but it's going to be a long road.

Speaking of Windows and performance, how about that RAM crisis? Microsoft is feeling the squeeze too, and is apparently doing work up and down the Windows stack to improve its memory consumption. Microsoft's Windows chief Pavan Davuluri has admitted that the rising cost of memory is pushing the company to make Windows 11 use less RAM. Microsoft is working on the Windows memory manager, memory compression, WinUI 3 and WebView2, and has made "memory optimization for 8GB and above" an official priority for the rest of 2026. ↫ Abhijith M B at Windows Latest This might be the only positive consequence of the RAM crisis.

To this day, Windows retains full support for the old MS-DOS 8.3 filename limitation, and it does this by creating 8.3 aliases for files with longer names. Apparently, this has a measurable effect on performance, so naturally, people are going to turn it off to make their Windows installations perform better. According to the user, this resulted in noticeably smoother scrolling in Tile view. They subsequently repeated the process on several folders they regularly use and reported that searching through files became much faster. The user also claimed that external hard drives became faster and that browsing an Android directory over USB or FTP behaved more like a regular Windows folder, including when copying large numbers of music files. ↫ Sayan Sen at Neowin You can disable this legacy feature in Windows per volume or globally, but Microsoft is warning users not to do so. Even in 2026, applications and registry entries may depend on 8.3 filenames being available, so removing them can lead to unexpected outcomes. It's just one of those things you wouldn't expect to still be around or have a measurable impact in the days of fast SSDs, but there's enough credibly evidence out there to suggest that yes, it actually does negatively affect performance. If you're doing a lot of file operations in Windows, it might be worthwhile to do some testing of your own to see if you can speed things up. Or, you know, you can just not use a house of cards disguised as a serious operating system.

Apple's macOS has a Full Disk Access permission, designed to allow backup applications full access to, well, the disk, so they can perform their job properly. Apple posted a notice on its website that it's going to further restrict this permission, because some applications were abusing this permission to gain access to users' messages, emails, and so on, which it obviously isn't intended for. What kind of applications, you may ask? Going forward, we will introduce additional controls to ensure that users who genuinely wish to grant an app this extraordinary level of access can only do so with very explicit user action. Addressing this is critical. As AI agents become increasingly capable and autonomous, the risks associated with this level of access will grow substantially. We are committed to ensuring users clearly understand these risks before granting such access, so they can make informed decisions about their own data and privacy. ↫ Announcement from Apple This was prompted by a story a few weeks ago, where Facebook's Muse "AI" tool was apparently reading people's private messages and other data, and even sent messages on users' behalf, without informing its users. It's incredibly naive to think Facebook software in 2026 would not do creepy things, so I'm honestly not at all surprised. It makes sense in Apple's worldview to further restrict permissions in response, but I'm sure more experienced macOS users are not going to like this.

The KDE project recently brought back its classic Oxygen and Air themes, but what if you prefer something… A little older? A modern recreation of the classic KDE 3 desktop experience for KDE Plasma 6, built entirely using Qt 6 and Qt Quick, with full support for Wayland and fractional scaling. ↫ Klassik GitHub page Neat.

Google launched its Googlebooks platform a week ago, and a lot of people were wondering what this meant for Chrome OS and Chromebooks. Since Googlebooks and its Android-based Googlebook OS lack the management frameworks markets like schools require, Chromebooks will continue to be available for now, until such time Googlebooks catch up in that regard. However, in a support document, Google states that update support for all Chromebook devices will end in 2034: ChromeOS devices will continue to receive regular updates and security patches through mid-2034. For qualifying devices purchased today whose 10-year support lifecycle extends beyond 2034, Google is committed to supporting your transition to Googlebook OS, with many devices offering direct migration paths. ↫ Google support document Google promised 10 years of updates for all Chromebooks, and it's now breaking that promise for anyone buying a Chromebook between now and whenever the last Chromebook rolls off the production line. Sadly, we live in a world where corporations are free to make and break whatever promises they want virtually free of consequences, and as society we're so used to it that anti-consumer behaviour like this barely elicits a shrug. Google does state that "many newer commercial Chromebook models will be capable of upgrading to Googlebook OS", but that, too, is just another promise - and a vague, one at that - so who knows how many devices will actually be capable of upgrading out in the real world. On top of that, we have no idea if Googlebooks will just be yet another in a long line of quickly abandoned Google tablet/laptop projects, further adding to the uncertainty. Stuff like this should not be legal.

In June 2008 Apple announced Mac OS X Snow Leopard, proudly boasting that it would have "no new features". Instead of piling on new things, Snow Leopard aimed to build on the success of its predecessor, Leopard, opting to focus on under-the-hood performance and stability improvements throughout the system. 18 years later, Apple is taking a similar approach with macOS 27. Golden Gate aims to fix the missteps of last year's Tahoe, promising an expansive set of improvements and "a more responsive and delightful experience". Does it hold up? Here are just some of the bugs I've encountered in my daily use over the past couple of weeks. ↫ Chester at SquareOrbits I'm getting some real Windows 11 vibes from this long list of bugs and issues, further underlining my perception that Apple completely lost the plot when it comes to Mac OS X (in the past) and MacOS (today). These are not the kind of things you'd find in the heydays of Mac OS X, back when I was a devout user, and makes me glad I abandoned ship long, long ago (around the time of the Intel transition). I don't see stuff like this in GNOME or KDE, and while not nearly as bad as Windows 11, the cracks are obvious. I am by no means an expert at how Apple is run and how it organises itself, but as a layperson I do wonder if the company is simply trying to do too much - too many different platforms, too many different crucial components it all develops internally, too many different markets to please. Things are going to fall through the cracks when you try to keep this many plates spinning.

A brand new Tcl/Tk release, in the form of Tcl/Tk 9.1. The new features in Tcl are a bit difficult for me to properly parse as a non-developer, but Tk's improvements are easy to understand: it brings supports for screen readers, initial supports for bidirectional and RTL scripts, improved listbox selection colours, and more. It also happens to drop support for Windows XP appearances, if that's something that matters to you.

Microsoft has announced WSL containers for developers who aren't already using Docker, Podman, or Rancher on their Windows workstations. WSL containers is now generally available! Check out this blog post to learn more about this overall feature enabling seamless access to Linux containers on Windows via the new "wslc.exe" command. This new Linux container platform comes with multiple architectures changes compared to WSL, which we'll detail in this post. ↫ Pierre Boulay at the Microsoft Dev Blogs If you already have WSL installed, you can run wsl -update to get this new container feature, or you can download it straight from GitHub.

Over the last few days and weeks or so, a few of the people I follow and interact with on Fedi have been talking about centralising information, tools, applications, and expertise from the Motif (and Xt, Xlib, and X11) ecosystem. There's a ton of information, resources, and actively maintained applications out there, but it's all spread out and sometimes difficult to find, and so Thomas Adam - one of the core developers of FVWM, among other things, as well as creator of CoW (FVWM for Wayland, more or less) - has created an effort to centralise all of this. Motif Central brings together information about Motif, Xt, Xlib and X11: how they fit together, how to program with them, and where to find the manuals, examples and historical material that explain them. Begin with the X programming stack, build your first Motif application, or explore the programming resources. The history pages describe the libraries' origins, while the archive guide helps you navigate older documentation. ↫ MotifCentral There's been a whole flurry of activity around Motif lately, including the updated and maintained fork we talked about a few weeks ago. The people loosely collaborating on MotifCentral also submitted patches to CDE to make sure it works on the new Motif fork, with the CDE developers setting up a build pipeline for easier testing. Making sure CDE, the classic Motif desktop environment, works well with the maintained Motif fork quite a few people seem to be rallying around is a worthwhile effort. We're still quite far from a complete(-ish) modern Motif ecosystem, but it's very heartwarming to see just how many people are actually still interested in it. My perhaps misguided hope is that we can somehow get to a modernised Motif/CDE desktop environment and applications, making it possible to more easily run a modern Motif environment on Linux and the BSDs. One may dream.

Windows 11 received its September update on the 8th of this month, and within days Microsoft had acknowledged or investigated problems involving Remote Desktop, USB audio, Linux and WSL-based apps like Claude Cowork, and enterprise domain issues. Windows Latest also found File History failures, Explorer.exe crashes, and AMD GPU instability, with an emergency update following on September 14 that still did not fix everything. This got us curious, and we looked back across the nine monthly updates released from January through September 2026 and, rather unsurprisingly, Windows 10 update history isn't infected with nearly as many bugs as that of Windows 11. ↫ Abhijith M B at Windows Latest Of course, Windows 10 also isn't getting nearly as much attention from Microsoft, but that's kind of the whole point, isn't it? Whenever Microsoft touches something, especially over the last 5 years or so, it's one cascade of failures after the other, eroding trust in Windows' updates even more (if that's even possible). In that light, why would you want to use Windows 11 and all the headaches that come with it, when Windows 10 is right there, still being supported, albeit without the latest bells and whistles that only seem to break Windows 11 anyway? If you really do need or want to use Windows, consider switching back to Windows 10 whenever the usual Windows reinstallation time draws near. You won't lose much, but will gain quite a bit in the process. Of course, this won't be a responsible or usable choice forever, but at this point in time, I definitely think it's the optimal choice for quite a few people.

One of the unwritten rules of the Internet seems to be that whenever something Amiga-related is mentioned, at least one Amiga fan (myself included) must show up and try to explain the concept of screens. Amiga screens can have different resolutions, we'll tell you, and one can drag them, we'll say, and other Amiga users rally in agreement, while non-Amiga users probably still don't get what's so great about screens. Until now, when this text has been written, in the hope of converting unsuspecting normies into full-blown Amiga screen lovers. ↫ Carl Svensson A deeply technical look at not just how the Amiga managed to achieve this stunning functionality way back in the '80s on machines with 7MHz and less RAM than a keyfob, but also how this functionality can be useful. I've always found the concept of screens on the Amiga quite interesting, and Svensson's article does a great job at demystifying the whole concept. Of course, expect a lot of lovely Amiga OS screenshots.

It's time for an overview of another month of Redox OS progress, and over the month of August - they're a bit late, don't believe the publication date - they've implemented multicore support for ARM, and considerably improved the I/O performance for the NVMe driver, RedoxFS, and RAMFS by implementing a ring buffer communication API. There's also initial support for NUMA-based memory management, QEMU is now working on Redox, and much more. Of course, there's also the usual long list of improvements to the kernel, relibc, drivers, and more.
