Microsoft is drawing a line in the sand: if you’re still on Windows 10, it wants your next PC to run on Arm processors and pack a powerful neural engine. With the October 14, 2025 end-of-support deadline fast approaching, the company is betting big on its Copilot+ PC initiative—a new class of devices that combine Arm-based chips with NPUs capable of at least 40 trillion operations per second. The pitch: better battery life, new on-device AI features, and now enough native app coverage to handle the vast majority of what people do everyday.

That message is landing at a critical moment. Millions of Windows 10 users, both consumers and businesses, are facing a forced hardware upgrade because their existing machines can’t run Windows 11. Microsoft is seizing the opportunity to not just push Windows 11, but to steer the ecosystem toward a future built around Arm and AI—even if it means leaving some legacy software behind.

What Microsoft Is Promising with Copilot+ PCs

The Copilot+ spec isn’t just a marketing label. It’s a hardware floor. Devices that carry the branding must include an NPU that hits 40+ TOPS—a measure of how many elementary AI operations the chip can perform per second. As of early 2025, that means laptops with Qualcomm’s Snapdragon X series, AMD’s Ryzen AI 300 series, or Intel’s Core Ultra 200V series. Microsoft’s own documentation is explicit: the NPU is the gatekeeper for a set of AI experiences that won’t run on older silicon.

Those experiences are already rolling out in waves. Copilot+ PCs get access to tools like Cocreator in Paint (which turns sketches into AI-generated art), enhanced Windows Studio Effects for camera and audio, live captions, and the controversial Recall feature that captures a searchable timeline of your activity. Many of these work locally, leaning on the NPU for speed and privacy. In fact, Microsoft has positioned the NPU as the key to doing AI on-device, without a cloud round-trip.

On the app compatibility side, Microsoft is trotting out a new metric: not how many apps are compiled for Arm, but how much time users spend in those native apps. The company says roughly 90% of total user minutes on Windows on Arm devices are now spent in apps that run natively—including Chrome, Office, Teams, Spotify, Netflix, and WhatsApp. That’s a figure echoed by several independent outlets, though the raw data behind it hasn’t been published. The message is clear: for the core productivity, browsing, and communication tasks, Arm is no longer a compromise.

Smoothing the path for everything else is Prism, an updated x86/x64 emulator that ships in Windows 11 24H2. Prism not only speeds up translated code but now supports CPU instruction extensions like AVX, AVX2, BMI, FMA, and F16C—instructions that some professional applications need to even launch. Microsoft has shown, for example, that Adobe Premiere Pro 25 can run under emulation on Copilot+ Arm devices, something previously impossible. It’s not perfect—32-bit helper processes are still left out, and emulation always carries a performance hit—but it removes a major roadblock for many users.

What This Shift Means for You

The calculus changes depending on who you are.

For home users: If your current PC is eligible for Windows 11, you don’t need a Copilot+ machine to stay supported. But if you’re buying new anyhow, an Arm-based Copilot+ laptop could give you noticeably longer battery life (Microsoft claims up to 22 hours of video playback on some models) and access to AI features that won’t work on standard Intel or AMD laptops. The catch is cost—these are premium devices—and compatibility. Check the WorksOnWoA community database to see if your must-have apps run natively or under Prism. If you rely on obscure or older software, you may hit snags.

For IT administrators and enterprises: The Windows 10 deadline is not flexible. You can buy Extended Security Updates (ESU) for up to three years, but that’s a bill—and it only covers security patches, not new features. Copilot+ PCs are designed to be modern management-friendly, with Secured-core PC status and deep integration with Intune. But before you commit, pilot a device. Microsoft offers the App Assure Arm Advisory Service at no extra cost—engineers will help you port or remediate critical line-of-business apps. Use that. And consider hybrid strategies: for stubborn legacy apps that just won’t budge, Windows 365 Cloud PC or Azure Virtual Desktop can fill the gap while you migrate.

For developers and ISVs: The Arm tide is rising. If you maintain a Windows app, native Arm64 support is becoming a competitive checkbox. Microsoft’s App Assure program can help you get there, and the expanded Prism emulation means even if you’re not ready, your app might still run on the new devices—but you’ll want to test thoroughly.

How We Got Here

This moment has been years in the making. Windows 10 launched in 2015 with a “Windows as a service” model, but Microsoft eventually drew a hard line with Windows 11’s hardware requirements, mandating TPM 2.0 and specific CPUs. That left a huge install base stranded. The October 2025 cutoff date was set early, giving the industry ample warning, but adoption of Windows 11 has been slower than Redmond hoped.

Parallel to that, Microsoft has been trying to make Windows on Arm a thing since the ill-fated Surface RT in 2012. The Surface Pro X in 2019 ran on a Qualcomm processor but suffered from slow emulation and a barren app store. Then Apple’s M1 Macs in 2020 showed that Arm laptops could be fast and efficient. Microsoft partnered with Qualcomm to create the Snapdragon X series, built for PC-class performance, and wrapped the whole effort in the Copilot+ brand in 2024. The combination of a real deadline, better silicon, and finally a credible app story has turned the migration recommendation from a whisper to a megaphone.

What to Do Now

Here’s a practical checklist if you’re facing a Windows 10 upgrade decision:

  1. Run Microsoft’s PC Health Check to see if your current hardware can run Windows 11. If yes, you can stay on x86/x64, but you won’t get Copilot+ AI features unless you buy new.
  2. Inventory your apps. List the software you can’t live without. Check the WorksOnWoA website or your vendor’s support pages for Arm status. Pay special attention to peripherals (printers, scanners) and security tools.
  3. Pilot a Copilot+ device. If you’re in an organization, acquire one or two machines and test everyday workflows. Engage App Assure earlier rather than later for any showstoppers.
  4. Weigh ESU vs. new hardware. ESU for consumers will come at a cost (Microsoft hasn’t finalized pricing for individuals, but businesses already have set plans). If your machine is old and you need to replace it within a year or two, a new Copilot+ PC may be more economical than paying for year-by-year security patches.
  5. Plan for sustainability. If you do upgrade, ask your vendor about trade-in programs. Responsible disposal and recycling can take some sting out of the forced refresh.

Outlook: What to Watch Next

The Copilot+ PC category is still young. We expect Microsoft to announce more on-device AI features throughout 2025, likely tied to new Insider builds. Competition among chipmakers will be fierce, which could drive prices down—good news for buyers. On the other hand, the environmental and anti-consumer arguments against forced hardware upgrades won’t vanish. Regulatory scrutiny could intensify if Microsoft’s messaging is seen as too aggressive. And the ultimate test for Windows on Arm will be whether the compatibility gap truly closes for the remaining 10% of apps. If it does, the October deadline could mark the beginning of an Arm-first era for Windows. If not, it’ll be remembered as another bump in the road.

For now, the advice is consistent: don’t panic, but don’t wait. Validating your own app compatibility today is the single best move you can make.
