Windows 10 vs Windows 11: Should You Upgrade in 2026?

If your PC still runs Windows 10, the short answer is: Windows 11 is now the safer choice, because Windows 10 stopped receiving free security updates on October 14, 2025, and Microsoft's paid Extended Security Updates (ESU) program for consumers only runs through October 12, 2027. Beyond that support-status urgency, Windows 11 also brings a redesigned interface, tighter hardware-based security (TPM 2.0, Windows Hello, Microsoft Pluton on newer silicon), and features like Copilot, Auto HDR and DirectStorage that Windows 10 will never get. Whether you should upgrade right now depends mostly on one thing: whether your current PC actually meets Windows 11's minimum hardware requirements.

Why this comparison matters right now: Windows 10's support clock

Windows 10 reached end of support on October 14, 2025. According to Microsoft, that means PCs still running Windows 10 no longer receive the software and feature updates, security updates and fixes, or technical support that had kept the operating system patched for over a decade. Microsoft is explicit that the devices themselves keep working, but "without ongoing security patches, systems become increasingly vulnerable to viruses and malware, and may experience performance degradation" over time.

Microsoft's answer for people who aren't ready to switch immediately is the consumer Extended Security Updates (ESU) program, which extends critical and important security patches — and only those, with no new features and no general technical support beyond ESU enrollment help — through October 12, 2027. Enrollment is available to individuals on Windows 10, version 22H2, for personal use in most markets (it excludes organization-managed devices), and one ESU license can cover up to 10 devices. Microsoft offers three ways to enroll: at no cost if you sync your PC settings via Windows Backup, by redeeming 1,000 Microsoft Rewards points, or through a one-time $30 USD payment (plus applicable tax). We covered the enrollment mechanics in detail in our Windows 10 ESU guide.

The practical takeaway: ESU is a bridge, not a destination. It buys time, not new features, and it runs out in under two years from today. That's the backdrop against which every Windows 10 vs. Windows 11 decision in 2026 should be made.

Windows 11 vs. Windows 10: what's actually different

Windows 11 isn't a cosmetic reskin of Windows 10 — though the interface changes (a centered Start menu and taskbar, rounded corners, Snap Layouts) are the most visible difference. The deeper differences are in security architecture, AI integration, and the pace of new features, since Windows 10 is now effectively frozen except for ESU security patches.

On Windows 11, Microsoft ships continuous feature updates outside the traditional yearly cycle — what it calls "continuous innovation" — plus periodic named feature updates like the current 25H2 release. According to Microsoft's own documentation for IT professionals, Windows 11, version 25H2 is delivered as a small, fast "enablement package" on devices already running 24H2, since most of its underlying files are already present via monthly updates. It also resets the support clock: 24 months for Home and Pro editions, 36 months for Enterprise and Education. We detailed what's new in that release in our Windows 11 25H2 explainer.

Recent Windows 11 feature work Microsoft has documented includes:

• Copilot and on-device AI: A built-in AI assistant accessible from the taskbar, plus AI actions in File Explorer (background removal, image edits, document summaries) and an AI-assisted Paint and Clipchamp.
• Quick machine recovery: Automatic, cloud-assisted recovery from widespread boot failures, reducing manual troubleshooting.
• Wi-Fi 7 support: Enterprise-grade wireless networking support added in the 25H2 update.
• A leaner OS: Legacy components like PowerShell 2.0 and the WMIC command-line utility have been removed from Windows 11, version 25H2, per Microsoft's release notes.
• Copilot+ PC exclusives: Features like Recall (preview), Click to Do, and semantic (AI-powered) Windows search are limited to Copilot+ PCs with a qualifying NPU — they won't run, even on Windows 11, without the right hardware.

None of this reaches Windows 10, which by design only receives ESU security fixes now, not feature updates.

Performance, gaming and RAM usage: what's actually confirmed

This is an area where it pays to separate marketing claims from documented facts. Microsoft's Windows 11 upgrade guidance advertises "faster performance" and gaming optimizations as general upgrade benefits, but Microsoft does not publish a head-to-head Windows 10 vs. Windows 11 benchmark or a specific RAM-usage comparison between the two operating systems — so treat any specific percentage claims you see elsewhere with caution. What is documented is the feature set: Windows 11 supports Auto HDR, which Microsoft's support documentation describes as automatically increasing the color range and brightness of older SDR-only games so they look closer to HDR titles on a compatible HDR10 display. Windows 11 also supports DirectStorage, an API designed (per Microsoft's developer documentation) to reduce CPU overhead when loading game assets from a fast NVMe SSD directly to the GPU — though the practical benefit depends on having compatible hardware and games that use the API.

On minimum requirements, the baseline is actually similar: Microsoft lists 4GB of RAM as the minimum for Windows 11, the same floor Windows 10 has used for years. In other words, the official minimums don't show Windows 11 as dramatically heavier — the more relevant difference for older hardware is the security-chip requirement (TPM 2.0) and CPU compatibility list, covered next, not raw RAM or storage numbers. If your current machine is short on storage regardless of which OS you run, our guide on freeing up disk space on Windows 11 covers practical ways to claw back room.

Security: the real dividing line

Security architecture, not the interface, is arguably the biggest substantive gap between the two operating systems. Windows 11 requires TPM 2.0 (Trusted Platform Module) on every device, new or upgraded. Per Microsoft's Windows 11 security documentation, TPM technology provides hardware-based security functions that Windows Hello, BitLocker, System Guard and other Windows features depend on for key generation, secure storage, encryption, boot-integrity measurement and attestation. TPM 2.0 specifically supports newer cryptographic algorithms than TPM 1.2, which is one reason Microsoft made it a baseline requirement rather than an optional feature.

On top of that, some newer PCs include the Microsoft Pluton security processor, which Microsoft describes as integrating the security chip directly into the CPU silicon rather than placing it on a separate motherboard chip — reducing the physical attack surface for extracting encryption keys or credentials. Pluton is available on select devices with Qualcomm Snapdragon X, AMD Ryzen AI, and Intel Core Ultra 200V series processors, and it works as (or alongside) a TPM 2.0 implementation.

Windows 10 can use TPM 1.2 or run without a TPM in many configurations, meaning large numbers of Windows 10 PCs simply cannot offer the same hardware-rooted security guarantees, regardless of how many software patches they receive. That's a structural gap ESU cannot close, since ESU only covers OS-level security patches, not architectural hardware protections.

Windows 11 hardware requirements — and how to check your PC

Before deciding anything, check whether your current PC is actually eligible. According to Microsoft's official specifications page, the minimum requirements are:

Your PC must also already be running Windows 10, version 2004 or later, to take the free in-place upgrade path. Microsoft's free PC Health Check app will scan your device and tell you whether it qualifies — and if not, which specific requirement it fails. That's the fastest way to get a real answer rather than guessing from a spec sheet.

If your PC can't run Windows 11

Plenty of otherwise-functional PCs fail the Windows 11 check, most commonly on the TPM 2.0 or CPU compatibility requirement. If that's your situation, you have a few realistic paths, none of them "just keep using Windows 10 forever without consequences":

• Enroll in ESU as a bridge. This buys you security patches only through October 12, 2027, giving you time to plan a hardware refresh — it isn't a long-term fix.
• Check for a firmware fix. Some PCs have TPM 2.0 or Secure Boot capability that simply isn't enabled in BIOS/UEFI settings; Microsoft's support documentation notes this is worth checking with your device manufacturer before assuming a device is ineligible.
• Replace the hardware. If your PC is old enough to fail Windows 11's CPU list, it's also likely nearing the end of its useful life for other reasons (battery, storage speed, general age).
• Move to a different OS entirely. If the machine still works fine for browsing and light tasks but can't run Windows 11, a lightweight alternative operating system is a legitimate option for extending its life rather than running an unsupported OS indefinitely.

How to upgrade from Windows 10 to Windows 11

If your PC is eligible, Microsoft's documented process is straightforward: open Settings, go to Windows Update, and select "Check for updates." If your device qualifies, the Windows 11 upgrade will be offered there, or you can confirm eligibility first with the PC Health Check app. Back up important files before any major OS upgrade — Windows Backup can handle this as part of the same flow described in Microsoft's Windows 11 ESU-to-11 migration guidance. The in-place upgrade preserves your files, apps and settings in the large majority of cases, though a full backup remains good practice for any operating-system-level change.

Should you upgrade now? The bottom line

For eligible PCs, the decision is close to a formality at this point: Windows 10 no longer receives free security updates, ESU is a temporary and shrinking bridge that ends in under two years, and Windows 11 has had years to mature since its 2021 launch — the rough edges that concerned early adopters (app compatibility, driver support, interface complaints) have largely been addressed through subsequent updates including 25H2. Waiting doesn't make your PC more secure; it just delays an upgrade you'll eventually need to make anyway, while running unpatched software in the meantime unless you pay for ESU.

For ineligible PCs, the calculus is different and more personal: weigh the cost of new hardware, the remaining useful life of your current machine, and whether ESU's 2027 cutoff gives you enough runway to plan a replacement on your own schedule. What doesn't make sense for either group is treating "do nothing" as a neutral, no-cost option — Windows 10's support status changed in 2025, and that change is permanent.
