Windows 10 vs Windows 11 at a Glance

The Most Important Difference in 2026: Windows 10 Support Has Ended

The biggest difference between Windows 10 and Windows 11 is no longer the Start menu, taskbar or visual design. It is their support status.

Microsoft ended normal support for Windows 10 on 14 October 2025. A Windows 10 PC does not stop working because of that date, but normal Windows 10 servicing no longer provides:

• regular security updates and fixes;
• feature updates;
• general software updates for Windows 10; or
• normal Microsoft technical support for the operating system.

What is Windows 10 ESU?

Microsoft's Extended Security Updates (ESU) programme gives eligible Windows 10 users additional time to move away from the operating system.

For eligible personal devices running Windows 10 version 22H2, the Consumer ESU programme can provide critical and important security updates until 13 October 2026.

ESU does not turn Windows 10 back into a normally supported operating system. It does not provide new Windows features, general product improvements or normal Windows 10 technical support.

Windows 10 vs Windows 11 Interface and Design

Windows 10

Windows 10 uses the familiar left-aligned Start menu with a mixture of an application list and Live Tiles. Its notification and quick-setting controls are presented through the Windows 10 interface that many users became familiar with over its ten-year life.

Windows 11

Windows 11 introduced a cleaner visual design with rounded windows, an updated Start menu and taskbar icons positioned in the centre by default.

The taskbar icons can be moved back to the left through Windows settings, so users moving from Windows 10 do not have to keep the centred alignment.

Is Windows 11 difficult to learn?

Usually not. The visual layout has changed, but the basic way Windows operates remains familiar. File Explorer, the desktop, taskbar, Start menu, application windows and Settings are still recognisably Windows.

For most users, the biggest adjustment is finding where Microsoft has moved or redesigned particular controls rather than learning an entirely different operating system.

Is Windows 11 Faster Than Windows 10?

There is no useful answer that applies to every computer.

Windows performance depends heavily on the processor, RAM, graphics hardware, storage, drivers, background applications and the particular workload being used.

A modern PC designed for Windows 11 may perform extremely well with it, while an older PC can sometimes feel more comfortable on Windows 10 simply because its hardware and drivers were designed around the older operating system.

SSDs make a bigger practical difference

If an older PC still uses a mechanical hard drive, changing to an SSD can often have a much more noticeable effect on startup and application responsiveness than the choice between Windows 10 and Windows 11 alone.

Windows 10 vs Windows 11 Security

Both Windows 10 and Windows 11 introduced substantial security technologies during their lifetimes, but Windows 11 places stricter hardware security requirements on supported PCs.

TPM 2.0

A supported Windows 11 installation requires Trusted Platform Module version 2.0. TPM provides hardware-backed security functions used by Windows and compatible security features.

Secure Boot and UEFI

Windows 11 also requires UEFI firmware with Secure Boot capability. Secure Boot helps protect the startup process against unauthorised software loading before Windows.

Windows Security

Windows 11 includes Windows Security, Microsoft Defender Antivirus, firewall protection and other built-in security technologies.

The key issue for Windows 10 in 2026 is not that it never had security features. It is that the operating system has reached end of support and therefore no longer receives normal security servicing unless the device is covered by an applicable ESU programme.

Windows 11 Has Stricter Hardware Requirements

This is one of the main reasons some otherwise usable Windows 10 computers cannot officially move to Windows 11.

The minimum Windows 11 requirements include:

• Processor: 1 GHz or faster with two or more cores on a compatible 64-bit processor or system on a chip
• Memory: at least 4 GB RAM
• Storage: at least 64 GB
• Firmware: UEFI with Secure Boot capability
• TPM: Trusted Platform Module version 2.0
• Graphics: DirectX 12 compatible graphics with a WDDM 2.0 driver
• Display: a 720p display larger than 9 inches diagonally

The processor must also appear on Microsoft's supported processor list. Simply having a processor faster than 1 GHz does not guarantee Windows 11 compatibility.

Multitasking and Productivity

Windows 10 already includes useful multitasking tools such as window snapping, Task View and virtual desktops. Windows 11 develops these ideas further.

Snap in Windows 11

Windows 11 provides more flexible Snap layouts for arranging several application windows on screen. On compatible layouts, you can quickly place applications side by side or into multi-window arrangements without manually sizing each one.

For people who regularly work with a browser, email, documents and spreadsheets at the same time, this can make better use of a large monitor.

See our Windows 11 Snap Layouts guide for more detail.

Multiple desktops

Both operating systems support virtual desktops, but Windows 11 provides a more developed desktop-management experience for separating projects, workspaces or personal and work applications.

Windows 10 vs Windows 11 for Gaming

Windows 10 remains capable of running a large library of PC games, but Windows 11 is now the Windows platform being developed and supported for future use.

Windows 11 includes support for gaming technologies such as:

• DirectX 12;
• Auto HDR on compatible displays;
• DirectStorage on suitable hardware and supported games;
• Game Bar; and
• current Microsoft gaming services.

That does not mean every game will suddenly run faster after an upgrade. Frame rates and responsiveness still depend primarily on the graphics card, processor, RAM, storage, drivers and the game itself.

Windows 10 vs Windows 11 for Everyday Software

Most mainstream applications that have been kept up to date support Windows 11, but compatibility should never be assumed for specialist or older software.

Before upgrading a work computer, check any applications that are essential to your workflow, particularly:

• older accounting or database software;
• specialist engineering or manufacturing applications;
• legacy hardware-management tools;
• older printers, scanners and specialist peripherals;
• industry-specific software; and
• applications that depend on older drivers.

What If Your PC Cannot Run Windows 11?

If PC Health Check reports that your computer is not compatible, identify the exact reason before replacing anything.

Some PCs fail because TPM 2.0 or Secure Boot is available but disabled in the firmware. Other PCs fail because their processor or underlying platform is genuinely unsupported.

Do not force Windows 11 onto unsupported hardware just to leave Windows 10

Requirement-bypass tools and modified installation methods can allow Windows 11 to be installed on some unsupported systems, but doing so does not make the hardware officially supported.

If the PC cannot meet the Windows 11 requirements, the safer options are normally to:

1. check whether TPM or Secure Boot simply needs enabling;
2. check for manufacturer firmware updates;
3. use Consumer ESU temporarily if the Windows 10 PC is eligible and more transition time is needed; or
4. replace the computer with Windows 11-compatible hardware.

Should You Upgrade from Windows 10 to Windows 11 in 2026?

For most compatible computers, yes.

The situation is now different from the first few years after Windows 11 launched. This is no longer simply a question of whether the new Start menu, Snap Layouts or visual design are worth changing operating systems for.

Windows 10 has reached end of support. Therefore, if the computer:

• passes Windows 11 compatibility checks;
• supports your important applications;
• supports your essential printers and peripherals; and
• has no known manufacturer compatibility problem;

then remaining indefinitely on Windows 10 usually has little practical advantage.

Is the Windows 11 upgrade still free?

Microsoft continues to provide a free Windows 11 upgrade for eligible Windows 10 PCs that meet the Windows 11 requirements.

You can check through Settings > Update & Security > Windows Update on Windows 10, or use Microsoft's PC Health Check application to confirm compatibility.

Before Upgrading from Windows 10 to Windows 11

Before starting the upgrade:

• Back up important files.
• Run Microsoft's PC Health Check.
• Install current Windows 10 updates.
• Check for BIOS, firmware and driver updates from the PC manufacturer.
• Confirm that essential applications support Windows 11.
• Check specialist printers, scanners and peripherals.
• Confirm which Windows edition is currently installed and activated.

Windows 10 vs Windows 11: Final Verdict

Windows 10 was a successful operating system and remains familiar to millions of users, but in 2026 its end-of-support status changes the decision significantly.

If a computer is compatible with Windows 11 and the software and hardware you rely on also work with it, Windows 11 is now the better long-term choice.

Windows 10 still has a temporary role for PCs that cannot yet move to Windows 11, particularly where Consumer ESU is being used during a migration or hardware-replacement period. It should no longer be presented as an equal long-term alternative to a supported Windows 11 installation.
