Microsoft is secretly building Polaris, a slimmer, more modern version of Windows

Add as a preferred source on Google

Microsoft’s latest internal project is reportedly a new pared-down version of Windows code-named Polaris. This new iteration isn’t a successor to Windows 10, not in the traditional sense. Instead, it’s an alternative operating system more like iOS or Chrome OS — a lightweight OS designed for devices like ultra-mobile laptops, 2-in-1s, and tablets. And according to Windows Central, it could be the future of Windows.

So what is it, exactly? Good question. Last January, we reported on efforts to develop an “adaptive shell” called C-Shell for Windows 10 so that the platform can properly scale out across PC, mobile, console, HoloLens, and embedded devices. Different products running Windows would use different iterations of that shell. And according to noted Microsoft-watcher Mary Jo Foley, Polaris is Microsoft’s effort to build a desktop Shell using C-Shell to run on top of the Windows Core OS.

Maybe, maybe not. Here’s another theory: Polaris could take over for Windows 10 S, the pared-down student version of Windows 10 that Microsoft is using to test the lightweight OS waters.

Windows 10 S could be seen as something of a trial balloon here, with Microsoft angling toward the education market to see how a pared-down Windows experience would go over with the average user.

Polaris reportedly aims to strip out all the legacy components that make Windows 10 a full-featured operating system in favor of a system designed around the basics — like Chrome OS. An operating system designed for people who typically work out of a web browser. The new Windows Polaris would be quicker, more nimble, and carry a lot less baggage.

Polaris would, according to Window Central, be built entirely on Microsoft’s Universal Windows Platform, or UWP, making it a much more hospitable environment to existing UWP apps and potentially offer battery life and performance gains. (The world’s reaction to UWP has been … somewhat mixed.)

“The current Windows Shell is one of the major legacy components that Microsoft is replacing in Polaris; it is also stripping out legacy, unneeded Win32 components and apps like Notepad or Paint in favor of a UWP experience, just like Windows 10 Mobile,” Windows Central reports.

It’s an interesting move and it certainly makes sense with Microsoft’s recent shift toward unifying its Windows experience across all of its platforms, but it’s unclear whether or not Polaris would end up seeing widespread adoption. Currently, Chromebooks offer a unique niche for lightweight on-the-go computing, and Windows 10 exists in its full version on laptops and mobile devices up and down the price spectrum without any issues. Pulling out functionality in favor of marginal gains in performance and battery life might not appeal to the average laptop, tablet, or 2-in-1 user.

Intel may bring back older desktop CPUs because DDR5 is getting too expensive

Intel may be preparing an unusual response to the ongoing memory crunch. According to Chinese outlet ITHome, citing ChannelGate, the company’s latest production plan includes restarting production of 13th-gen and 14th-gen Core processors.

The move is expected to increase supply across Intel’s 10th, 12th, 13th, and 14th Gen CPU families, especially in mainland China. For DIY PC builders, the timing is important. DDR5 memory prices have climbed sharply, making newer platforms harder to justify for anyone trying to build an affordable gaming PC.

Amazon wants to design in-house chips for Kindles, Fire TV, and Echo speakers
Apple did it first. Amazon is doing it now, starting with 40 million chips a year and a partner most people have never heard of.

Apple's decision to design its own chips reshaped the consumer electronics industry. Amazon may be about to make the same call, just about two decades later.

Supply chain analyst Ming-Chi Kuo reports that Amazon is preparing to shift away from externally sourced processors for its consumer electronics lineup, marking what he describes as the company's first major processor procurement change in 20 years. The transition is expected to begin in 2027.

AI wants to summarize it all. TripAdvisor’s misleading reviews show AI will also ruin your travel plans
Spotless, friendly, and totally wrong. AI summaries are hiding the reviews that actually matter.

Planning a trip is stressful enough without wondering if the glowing hotel summary you just read was written by an AI that skipped the scary parts. As it turns out, that might be exactly what's happening on TripAdvisor.

According to an investigation by consumer group Which?, reported by the Guardian, TripAdvisor's AI-generated review summaries are smoothing over serious guest complaints, and in some cases, downright dangerous ones.
