Is my PC compatible with Windows 11? Simple and quick guide

With the arrival of Windows 11, many users ask the same question: is my computer compatible with Windows 11? Unlike previous versions, Microsoft has imposed new hardware requirements that make some PCs incompatible, even if they work perfectly under Windows 10.

In this simple guide, we will see how to check your PC's compatibility in a few minutes, without being a computer expert.

Minimum requirements for Windows 11

To install Windows 11, your computer must meet several criteria:

• Processor: 64-bit, 1 GHz or more, with at least 2 cores

• RAM: minimum 4 GB

• Storage: at least 64 GB available

• Graphics card: DirectX 12 compatible

• Screen: minimum 9 inches with HD resolution

• TPM 2.0 (mandatory)

• Secure Boot enabled

The last two points (TPM 2.0 and Secure Boot) are the ones that most often block installation.

What is TPM 2.0?

The TPM (Trusted Platform Module) is a security chip integrated into the motherboard. It is used to protect data, passwords, and encryption.

Without TPM 2.0, Windows 11 will refuse official installation.

Good news:
Most PCs sold after 2018 already have TPM, but it is sometimes disabled in the BIOS.

How to check compatibility automatically?

Method 1: official Microsoft tool

Microsoft offers a free tool called PC Health Check.

You just need to:

1. Download the tool from the Microsoft website

2. Start the scan

3. Read the result

In a few seconds, you will know if your PC is compatible or not.

Method 2: quick manual check

You can also check yourself:

Check TPM

• Press Windows + R

• Type: tpm.msc

• If a window opens with TPM version 2.0, it’s good.

Check Secure Boot

• Press Windows + R

• Type: msinfo32

• Line “Secure Boot State” → must be Enabled

My PC is not compatible: what to do?

Three possibilities:

1. Enable TPM in the BIOS

Often the TPM is present but disabled.
Simply enter the BIOS (F2, DEL, or F10 key at startup) and enable:

• Intel: PTT

• AMD: fTPM

2. Force the installation (not recommended)

There are methods to bypass the restrictions, but:

• no Microsoft support

• risk of bugs

• updates not guaranteed

This is not recommended for professional use.

3. Stay on Windows 10 (temporarily)

Windows 10 remains supported until October 2025.
After this date, there will be no more security updates.

Is it really necessary to switch to Windows 11?

Windows 11 brings:

• better security

• optimized performance

• modern interface

• future compatibility with software

For a compatible PC, the upgrade is clearly recommended, especially for professional use.

Clean installation or upgrade?

Two options:

• Direct upgrade: keeps your files

• Clean installation: fresh system, more stable (recommended)

A clean installation helps avoid slowdowns and errors inherited from Windows 10.

Need a Windows 11 license?

To legally install Windows 11, a valid activation key is required.

On licence24.ch, you can get:

• Windows 11 Home

• Windows 11 Professional

• lifetime licenses

• immediate activation

• support in French

Conclusion

Checking your PC's compatibility with Windows 11 is simple and quick.
In most cases, the problem comes solely from the TPM being disabled.

Before changing your computer, take 5 minutes to test:
You could save several hundred francs.

Windows 11 is today the best foundation for a secure, stable system ready for the coming years.
