The Latest Windows 11 Release Might Not Work On Your Oldest Machines

February 16, 2024 by 79 Comments

Everybody knows you can’t install Windows XP on a 386, or Windows 95 on an original IBM PC. But for Windows 11, the goalposts seem to be changing with newer releases of the existing OS. As covered by The Register, it appears the latest Windows 11 24H2 update might be incompatible with older machines.

It’s all down to the POPCNT CPU instruction. As shared on Twitter by [TheBobPony], the instruction appears in a number of Windows 11 system files, including kernel and USB XHCI drivers. Thus, it appears that any CPU not able to run this instruction will not be able to boot Windows 11. POPCNT was first included in AMD’s Barcelona architecture in 2007, and Intel’s Core processors in 2008. It’s an instruction for counting set bits in a word.

Ultimately, the effect is that computers with older CPUs will no longer be able to run the latest version of Windows 11. It could be as simple as Microsoft engineers enabling more modern CPU instructions at compilation time. However, given affected hardware is more than 15 years old, it’s perhaps likely that Microsoft is perfectly willing to cut these machines off from using the latest versions of its main operating system. We’ve talked about this phenomenon before, too.

In any case, keep a close eye on Windows update if you’re running super-old hardware. Let us know if you’ll be affected in the comments.

Building A Mouse That’s Also A Computer

January 25, 2024 by 27 Comments

Once upon a time, a computer was a big metal brick of a thing that sat on or next to your desk. Now, it’s possible to fit decent computing power into a board the size of a stick of gum. [Electo] took advantage of this to build an entire computer into a mouse form factor.

[Electo] had tried this before years ago, and built something pretty sloppy. This time, he wanted to build a version that had an actually-legible screen and fit better in the hand. He whipped up a giant 3D-printed mouse housing, and fitted the sensor board from an optical mouse inside. That was hooked up to an Intel NUC PC that fits inside the housing. A small LCD screen was then installed on a rack system that lets it pop out the front of the mouse. Data entry is via a laser keyboard mounted in the side of the mouse.

Of course, being based on an Intel NUC means the thing was the size of a couple of phonebooks. That’s not really a mouse. Starting again, he reworked the build around a tiny palm-sized computer running Windows 11. It was stripped out of its case and wedged into a compact 3D-printed housing only slightly larger than a typical mouse. It has a keyboard of a sort – really it’s just an array of buttons covering W, A, S, D, and a couple others for playing simple games. Amazingly, it’ll even run Minecraft or Fortnight if you really want to try and squint at that tiny screen.

Having a computer with a screen that moves every time you move the mouse isn’t ideal. At the same time, it’s fun to see someone explore a fun (and silly) form factor. It’s interesting to see how the project works compared to the original version from a few years ago. Video after the break.

Computer Speed Gains Erased By Modern Software

July 2, 2023 by 284 Comments

[Julio] has an older computer sitting on a desk, and recorded a quick video with it showing how fast this computer can do seemingly simple things, like open default Windows applications including the command prompt and Notepad. Compared to his modern laptop, which seems to struggle with even these basic tasks despite its impressive modern hardware, the antique machine seems like a speed demon. His videos set off a huge debate about why it seems that modern personal computers often appear slower than machines of the past.

After going through plenty of plausible scenarios for what is causing the slowdown, [Julio] seems to settle on a nuanced point regarding abstraction. Plenty of application developers are attempting to minimize the amount of development time for their programs while maximizing the number of platforms they run on, which often involves using a compatibility layer, which abstracts the software away from the hardware and increases the overhead needed to run programs. Things like this are possible thanks to the amount of computing power of modern machines, but not without a slight cost of higher latency. For applications developed natively, the response times would be expected to be quite good, but fewer applications are developed natively now including things that might seem like they otherwise would be.  Notepad, for example, is now based on UWP.

While there are plenty of plausible reasons for these slowdowns in apparent speed, it’s likely a combination of many things; death by a thousand cuts. Desktop applications built with a browser compatibility layer, software companies who are reducing their own costs by perhaps not abiding by best programming practices or simply taking advantage of modern computing power to reduce their costs, and of course the fact that modern software often needs more hardware resources to run safely and securely than equivalents from the past.

Tiny11 Makes Windows 11 Small

February 21, 2023 by 81 Comments

If you often spin up a virtual machine just to run Windows, you might be sad that you have to allocate so much space for it. The Tiny11 project provides a Windows 11 installer that strips and compresses a bare minimum system do under 8GB of space. We aren’t sure what the licensing aspects of it all mean, but there are a few things you need to know. You can see a video about the project below.

The installer requires you to activate Windows, so that’s probably a good thing from a legal standpoint. Besides being compressed, the installer, based on Window 11 Pro 22H2, removes sponsored applications and Teams. It does, however, have the component installer and the Microsoft store, so you can add back things you want that aren’t in the default install.

Mobile-Focused Windows 11 Leaves Taskbar Stuck Along The Bottom

April 19, 2022 by 96 Comments

Yeah, I’ll admit it: I’m a Windows person. Two years ago this summer, I traded in an overworked Windows 7 laptop that was literally screaming in pain for a SFF Windows 10 box as my main machine. But 10 might mean the end for this scribe, who has used Windows since the late 1980s. Admittedly, it’s for a fairly petty reason — Microsoft have gotten rid of alternate-location taskbar support in Windows 11. As in, you can have the taskbar anywhere you want, as long as it’s the bottom of the screen.

Years ago, I switched my taskbar to the top for various reasons. For one, it just made more sense to me to have everything at the top, and nothing at the bottom to interrupt visual flow while reading a web page or a document. Plenty of people move it to one of the sides or hide it when not in use for the same reason. More importantly, I thought moving the taskbar to the top would help with my neck/shoulder strain issues, and I believe that it has. So oddly enough, this one little thing may be the dealbreaker that gets me to switch after thirty-something years to Linux, where top-aligned taskbars are more or less the norm.

Linux On The Windows 11 Desktop

November 10, 2021 by 38 Comments

A month ago Microsoft officially released Windows 11. One of its features is the ability to run Linux GUI applications side by side as peers to normal Windows desktop apps. [Jim Salter] of Ars Technica took a closer look and declared it works as advertised.

This is an evolution of the Windows Subsystem for Linux (WSL), which has existed for a few years but only in command-line form. Linux being Linux, it was certainly possible to put visuals onscreen, but doing so required jumping through some hoops and dealing with limitations. Now “WSLg” gives a smoother and more accessible experience.

While tremendously valuable for those who need it, WSLg is admittedly a niche feature. The circumstances will be different for different needs. Around these parts, one example is letting us work with pieces of proprietary Windows software (such as low level hardware drivers or hardware-specific dev tools) while still retaining Linux tools for the rest of our workflow.

It’s also interesting to take a peek behind the scenes for an instructive look at bridging two operating systems. A Microsoft blog post describes the general architecture, where we were happy to see open-source work leveraged. And by basing this work on Wayland, it is more forward-looking than working with just X11.

The bad news is that WSLg is limited to Windows 11, at least for now. WSL users on Windows 10 will have to continue jumping through hoops (We described one method using X11.) And opening this door unfortunately also opened the door to security issues, so there’s still work ahead for WSL.

Well, at least the acronym will stay the same. It looks like black is the new blue for Windows 11, as the BSOD screen gets its first makeover in years. It’s an admittedly minor change, since the on-screen text is virtually identical to the BSOD from recent versions of Windows 10, and the new death-knell even sports the same frowny-face emoji and QR code. Really, the white-on-black color scheme is the only major difference we can see — even the acronym will stay the same. It’s not really that newsworthy, we suppose, although it does make us miss the extremely busy BSODs from back in the Windows NT days.

As the semiconductor shortage continues, manufacturers are getting desperate to procure the parts they need to make their products. And if there’s one thing as certain as death and taxes, it’s that desperation provides opportunity to criminals. A thread over on EEVBlog details an encounter one company had with an alleged scammer, who sent an unsolicited offer to them for a large number of ordinarily hard-to-find microprocessors at a good price. Wisely, the company explored the offer in some depth and found that “Brian” (the representative who contacted them) is actually named Nick Martin and, according to an article on the Electronic Resellers Association International (ERAI) website, is apparently associated with a number of fraudulent operations. Their list of allegedly fraudulent deals made by Mr. Martin stretches back to 2018 and totals over $300,000 of ill-gotten gain.

Last year, friend-of-Hackaday and laser artist Seb Lee-Delisle spent a lot of time and effort getting together an amazing interactive laser light show for the night skies of cities in the UK. Laser Light City, with powerful lasers mounted on the tops of tall buildings, was a smashing success that brought a little cheer into what was an otherwise dreadful time. But we have to admit that the videos and other materials covering Laser Light City left us wanting more — something like that, with a far-flung installation on rooftops and the ability for audience members to control it all from their phone, really needs a deeper “how it works” treatment. Thankfully, Seb has released a video that dives into the nuts and bolts of the show, including a look at ludicrously powerful lasers with beams that can still be seen in broad daylight.
