Windows 10 End of Life: Check if Your PC Is Compatible With Windows 11

Introduction

Windows 10 has officially reached the end of its support lifecycle, and millions of PC users are now facing an important decision: Can their existing computer run Windows 11?

Microsoft ended regular support for Windows 10 on October 14, 2025. Since then, standard Windows 10 installations no longer receive the normal free security updates, feature updates or technical support from Microsoft. Your PC will continue to work, but staying on an unsupported operating system can increase security risks over time.

The good news is that you don't necessarily need to buy a new computer.

If your Windows 10 PC meets Microsoft's Windows 11 hardware requirements, you may be able to upgrade for free.

In this guide, we'll explain how to check Windows 11 compatibility, what hardware requirements your computer needs, how to use Microsoft's PC Health Check tool and what you can do if your PC isn't officially supported.

Windows 10 Support Has Ended

Windows 10 reached its official end of support on October 14, 2025.

This applies to the standard Windows 10 Home and Pro editions, with Windows 10 version 22H2 being the final major version for those editions. Microsoft no longer provides normal security updates and technical support for these versions after the end-of-support date.

That doesn't mean your computer suddenly stops working.

You can still:

Start Windows
Open applications
Browse the internet
Play games
Access your files
Connect external devices

The problem is that the operating system is no longer receiving the same ongoing security protection.

That's why Microsoft recommends moving to Windows 11 on compatible hardware.

Does Every Windows 10 PC Need a New Computer?

No.

This is one of the most important things to understand.

Some Windows 10 computers are fully compatible with Windows 11.

If your PC meets the minimum hardware requirements, you can upgrade instead of replacing the entire machine.

Microsoft specifically recommends using the PC Health Check app to determine whether an existing Windows 10 device is eligible for Windows 11.

Before spending money on a new laptop or desktop, check your current computer first.

Windows 11 Minimum Hardware Requirements

Windows 11 has stricter hardware requirements than Windows 10.

Your computer generally needs to meet requirements involving:

Compatible 64-bit processor
At least 4GB of RAM
At least 64GB of storage
UEFI firmware
Secure Boot capability
TPM 2.0
DirectX 12-compatible graphics
Display larger than 9 inches with HD resolution
Internet connection for certain setup and update requirements

The processor requirement is particularly important for older PCs.

A computer can have plenty of RAM and storage and still be considered incompatible because its CPU isn't on Microsoft's supported processor list.

Why TPM 2.0 Matters

One of the biggest reasons older computers fail the Windows 11 compatibility check is TPM 2.0.

TPM stands for Trusted Platform Module.

It is a security technology designed to provide hardware-based protection for things such as encryption keys and other security credentials.

Windows 11 requires TPM 2.0 for officially supported installations.

Some relatively modern PCs actually have TPM 2.0 available but disabled in the firmware.

That means a computer that initially appears incompatible may become compatible after enabling the appropriate security setting in UEFI/BIOS.

However, you should not change firmware settings blindly.

The exact menu names differ between manufacturers.

What Is Secure Boot?

Secure Boot is another Windows 11 requirement.

It is a security feature available through modern UEFI firmware.

Secure Boot helps ensure that trusted software is loaded during the PC's startup process.

Like TPM 2.0, Secure Boot can sometimes already be supported by a computer but disabled in firmware.

Therefore, if the PC Health Check tool reports a problem related to Secure Boot, check your computer manufacturer's documentation before making changes.

Your Processor Is Extremely Important

Even if your computer has:

16GB RAM + 1TB SSD + TPM 2.0

it may still fail Windows 11 compatibility if the processor isn't supported.

Microsoft maintains processor compatibility requirements for Windows 11.

This is one reason simply comparing RAM and storage isn't enough.

For example, an older CPU can be powerful enough for everyday Windows 10 use but still fall outside Microsoft's official Windows 11 support requirements.

How to Check Your Windows 10 PC

The easiest method is Microsoft's PC Health Check application.

This is the recommended approach because it evaluates your computer rather than requiring you to manually check every specification.

Microsoft says Windows 10 users can download and run PC Health Check to determine whether their device is eligible for Windows 11.

Step-by-Step: Use PC Health Check

Step 1: Open Microsoft's PC Health Check Tool

Download and install the official PC Health Check application from Microsoft.

Avoid downloading random compatibility-checking programs from unknown websites.

Step 2: Open PC Health Check

Launch the application after installation.

The program provides information about your computer's health and hardware.

Step 3: Find Windows 11 Compatibility

Look for the Windows 11 compatibility section.

Select the option to check whether your PC can run Windows 11.

Step 4: Wait for the Result

The tool will evaluate your hardware.

You should receive a result indicating whether your PC meets the Windows 11 requirements.

Step 5: Read the Reason

If your computer isn't compatible, PC Health Check can identify the relevant requirement.

For example, the issue could involve:

Unsupported processor
TPM 2.0
Secure Boot
Insufficient storage
Other hardware requirements

This is much more useful than simply seeing a generic "not compatible" message.

You Can Also Check Windows Update

Microsoft provides another way to determine whether your computer is eligible.

On Windows 10, open:

Settings → Update & Security → Windows Update

Then select:

Check for updates

Microsoft says Windows Update can also indicate whether an existing Windows 10 PC is eligible for the Windows 11 upgrade.

However, PC Health Check provides a more direct compatibility assessment.

How to Check Your Windows 10 Version

Before upgrading, it's useful to know which version of Windows 10 you're running.

Press:

Windows + R

Then type:

winver

Press Enter.

A window will show your Windows version and build information.

For standard Windows 10 Home and Pro users, version 22H2 was the final feature update.

How to Check Your RAM

You can also manually check basic hardware information.

Open:

Settings → System → About

Look for:

Installed RAM

Windows 11 requires at least 4GB of RAM.

However, having 4GB doesn't necessarily mean the PC is fully compatible.

The processor, TPM, Secure Boot and other requirements also matter.

How to Check Your Processor

In:

Settings → System → About

look for:

Processor

Write down the exact processor model.

This information can help you determine whether your CPU meets Microsoft's supported processor requirements.

Again, don't assume that every modern-looking processor is automatically supported.

How to Check TPM 2.0

You can manually check TPM availability.

Press:

Windows + R

Type:

tpm.msc

Then press Enter.

Windows should display information about the TPM.

Look for:

Specification Version

If it shows 2.0, your PC has TPM 2.0 available.

If Windows reports that a compatible TPM cannot be found, the feature may be disabled in firmware or the computer may not have a supported TPM.

TPM Could Be Disabled

This is an important point for people with relatively modern computers.

Some PCs include TPM 2.0 but don't have it enabled.

On Intel systems, the technology may appear in firmware under a name such as:

Intel PTT

On some AMD systems, you may see:

AMD fTPM

The exact wording varies by manufacturer and motherboard.

If your PC Health Check says TPM is missing, check your manufacturer's support documentation before assuming that your hardware is incompatible.

How to Check Secure Boot

Press:

Windows + R

Type:

msinfo32

Press Enter.

The System Information window will appear.

Look for:

Secure Boot State

It may show:

Off

If it is off, your computer may still support Secure Boot but have it disabled.

Changing this setting can affect boot configuration, so make sure you understand your system's current firmware configuration before changing it.

What If My PC Is Compatible?

If your PC passes Microsoft's compatibility check, that's great news.

You generally don't need to purchase a new computer simply because Windows 10 support has ended.

You can upgrade the compatible machine to Windows 11.

Microsoft states that an eligible Windows 10 device can be upgraded to Windows 11 when it meets the required hardware specifications and is running a supported Windows 10 version.

Is the Windows 10 to Windows 11 Upgrade Free?

For eligible Windows 10 PCs, Microsoft supports upgrading to Windows 11 without requiring you to purchase a new Windows license.

The important requirement is that the computer must meet the Windows 11 hardware and eligibility requirements.

You should also make sure your existing Windows installation is properly activated.

Back Up Your Files Before Upgrading

Even when an upgrade is designed to preserve your files, you should always create a backup before performing a major operating-system upgrade.

Important files can include:

Photos
Videos
Documents
School work
Work files
Browser data
Game saves
Password-manager backups

You can use an external drive or a trusted cloud-storage service.

Don't start a major OS upgrade without protecting important data.

What If My PC Isn't Compatible?

Don't immediately throw the computer away.

You have several options.

Option 1: Check Whether TPM or Secure Boot Is Disabled

If the only problem is a disabled security feature, your PC may still be capable of meeting the requirements.

Check your manufacturer's instructions first.

Option 2: Continue Using Windows 10 Temporarily

Windows 10 continues to function after end of support.

However, Microsoft warns that standard Windows 10 no longer receives free security fixes and technical support after October 14, 2025.

Using an unsupported operating system indefinitely isn't recommended.

Option 3: Extended Security Updates

Microsoft offers an Extended Security Updates (ESU) program for eligible Windows 10 devices.

ESU can provide security updates beyond the normal end-of-support date.

This can be useful if you need additional time before upgrading your computer.

The availability and terms depend on the specific ESU program and user type.

Option 4: Buy a Windows 11 PC

If your computer is too old to meet Windows 11 requirements, replacing it may eventually be the simplest option.

A newer PC also gives you:

Better performance
Modern security hardware
Newer Wi-Fi
Better battery life
Faster storage
Longer software support

You don't necessarily need a high-end computer.

For everyday browsing, office work and media consumption, an affordable Windows 11 machine may be enough.

Option 5: Consider Another Operating System

If your old computer still performs well but isn't officially compatible with Windows 11, another option is installing a lightweight Linux distribution.

This can extend the useful life of older hardware.

However, Linux isn't a perfect replacement for Windows for everyone.

Before switching, check whether the software and games you use are supported.

Should You Install Windows 11 on Unsupported Hardware?

You may find online guides explaining how to bypass Windows 11 hardware checks.

These methods can sometimes install Windows 11 on computers that don't meet Microsoft's official requirements.

But there are risks.

An unsupported installation may not provide the same compatibility, reliability or update guarantees as a supported installation.

Microsoft's official recommendation is to use compatible hardware or move to a supported device rather than relying on unsupported configurations.

For a primary work or banking computer, sticking with supported hardware is generally the safer approach.

Don't Assume an Old PC Is Automatically Incompatible

Age alone doesn't determine Windows 11 compatibility.

A relatively recent computer may fail because of one missing requirement.

Another machine of similar age may pass.

That's why the best first step is simple:

Run PC Health Check.

Don't spend money on a new computer until you've checked your existing hardware.

Final Thoughts

Windows 10's end of support is an important moment for anyone still using Microsoft's older operating system.

But it doesn't automatically mean you need to buy a new PC.

The first thing you should do is check your current computer.

Use Microsoft's PC Health Check tool to determine whether your machine meets Windows 11's requirements. If it does, upgrading is likely the simplest solution.

If it doesn't, find out exactly why.

Your computer might only have TPM or Secure Boot disabled, or it could genuinely have an unsupported processor.

If the hardware is too old, you still have options such as Windows 10 Extended Security Updates, replacing the PC or installing a suitable alternative operating system.

The most important thing is not to ignore the end of Windows 10 support.

Your computer may continue working normally, but the lack of regular security updates makes planning your next step increasingly important.

Before buying a new PC, check your existing one. You might already have everything you need for Windows 11.
