Windows 10 vs. Windows 11: Key Differences

Origins and Release Timeline

Windows 10 was launched on July 29, 2015, as the successor to Windows 8.1. It was marketed as a “service” with ongoing updates, unifying the Windows experience across desktops, tablets, and smartphones (although the latter later phased out). Windows 10 quickly became the most widespread Windows version, appreciated for its stability and compatibility.

Windows 11 was officially announced in June 2021 and released on October 5, 2021. It marked a significant shift in Microsoft’s design philosophy, emphasizing a modern user interface and enhanced productivity features targeted towards both casual users and professionals. Despite a relatively shorter time on the market compared to Windows 10, Windows 11 is positioned as the future-proof OS, with ongoing developments and updates.

System Requirements and Compatibility

One of the earliest and most noticeable differences between Windows 10 and Windows 11 lies in the hardware requirements. Windows 11 introduces much stricter requirements to ensure a secure, stable, and modern computing experience.

Processor Requirements

Windows 10: Supports a wide range of processors, including older CPUs from Intel, AMD, and ARM.

Windows 11: Introduces stricter hardware requirements, including a compatible 64-bit processor with at least 1 GHz clock speed, 2 or more cores, and support for TPM 2.0 (Trusted Platform Module).

Pro Tip: Most computers built in the last 5-7 years should meet the processor requirements, but older systems may need to be upgraded or replaced.

Memory (RAM) Requirements

Windows 10: Minimum 2 GB for 64-bit systems.

Windows 11: Minimum 4 GB of RAM.

Recommended: 8 GB or more for optimal performance, especially when running multiple applications or using memory-intensive software.

Quick Note: If your computer has less than 4 GB of RAM, you’ll need to upgrade your memory before installing Windows 11.

Storage Requirements

Windows 10: At least 20 GB.

Windows 11: At least 64 GB, with optional plans for larger storage for modern features.

Recommended: 128 GB or more to accommodate Windows updates, applications, and personal files.

Pro Tip: Solid-state drives (SSDs) are highly recommended for Windows 11 as they provide much faster boot times and overall system performance.

Graphics Card Requirements

Windows 10: Supports a broad range of GPUs, including older integrated graphics.

Windows 11: Requires DirectX 12 compatible graphics / WDDM 2.x.

What this means: Most modern graphics cards from the last 5-6 years should meet this requirement, but very old or basic integrated graphics may not be compatible.

Critical Security Requirements

Secure Boot and TPM 2.0

Windows 11 mandates support for Secure Boot and TPM 2.0, aiming to enhance security and integrity. These are security features that help protect your computer from malware and unauthorized access.

Implication for Users: While Windows 10 can run on a wider variety of hardware, Windows 11’s hardware requirements aim to ensure a more secure and modern platform, though they also limit its compatibility with older devices.

What Is a TPM? (Trusted Platform Module)

At its most basic, the TPM is a tiny chip on your computer’s motherboard, sometimes separate from the main CPU and memory. The chip is akin to the keypad you use to disable your home security alarm every time you walk in the door, or the authenticator app you use on your phone to log in to your bank account.

How TPM Works

In this scenario, turning on your computer is analogous to opening the front door of your home or entering your username and password into the login page. If you don’t key in a code within a short period of time, alarms will sound or you won’t be able to access your money.

Likewise, after you press the power button on a newer PC that uses full-disk encryption and a TPM, the tiny chip will supply a unique code called a cryptographic key. If everything is normal, the drive encryption is unlocked and your computer starts up. If there’s a problem with the key—perhaps a hacker stole your laptop and tried to tamper with the encrypted drive inside—your PC won’t boot up.

Why TPM 2.0 Is Required

Enhanced security: TPM 2.0 provides hardware-based security features that protect your encryption keys, passwords, and other sensitive information.

BitLocker support: Windows 11’s BitLocker encryption relies on TPM to securely store encryption keys.

Future-proofing: TPM 2.0 ensures your computer meets modern security standards and can handle future security features.

How to Check Your Computer’s Compatibility

Using Microsoft’s PC Health Check App

Download the app: Microsoft provides a free PC Health Check app that can determine if your computer meets Windows 11 requirements.

What it checks: The app verifies processor compatibility, RAM, storage, TPM version, Secure Boot support, and graphics compatibility.

How to use: Download and run the app, then click “Check now” to see if your PC can run Windows 11.

Manual Compatibility Check

Check your processor: Look up your CPU model on the manufacturer’s website to see if it’s on the Windows 11 compatibility list.

Verify TPM support: Check your BIOS/UEFI settings to see if TPM is enabled and what version it supports.

Check Secure Boot: Ensure Secure Boot is enabled in your BIOS/UEFI settings.

Pro Tip: If you’re not comfortable checking BIOS settings, our technicians can help you verify these requirements.

What to Do If Your Computer Doesn’t Meet Requirements
