Read on to understand the steps, but remember that we're here to take over anytime.
Why upgrade from Windows 10 to Windows 11?
Let's be clear: at this point, the question is no longer really a choice, but a necessity. The number one reason to migrate is simple, direct and non-negotiable: the security of your computer equipment.

The main argument is the End of Support for Windows 10 at the End of 2025. Concretely, After the October 14, 2025, Microsoft will stop providing security updates, bug fixes, or technical support for this operating system. A computer still running Windows 10 will become a wide open door for Cyber Attacks, tea Viruses And the Ransomwares. Continuing to use it means knowingly exposing your business data and that of your customers to major risks. Migration is therefore above all a security imperative.
Beyond this urgency, upgrading to Windows 11 is also an opportunity to take a leap forward in technology and productivity. By migrating, you benefit from:
- Natively strengthened security: Windows 11 isn't just an update, it's a system built on modern security foundations. It requires components like the TPM 2.0 chip and secure boot to provide hardware protection against attacks, a much stronger barrier than Windows 10 can offer.
- A redesigned interface for productivity: With its centered Start menu, its refined taskbar and especially its functions such as “Snap Layouts” that allow you to organize your Windows in one click, the interface is designed to optimize multitasking and concentration.
- Optimized performances: The new system manages your computer's resources (RAM, processor) more intelligently. It's also designed to get the most out of solid-state drives, which means faster start-ups and better application responsiveness.
- Better integration of modern tools: The native integration of Microsoft Teams into the taskbar and the constant evolution of the application ecosystem make Windows 11 a platform more oriented towards new collaborative uses.
In summary, while the clock ticking is the main driver of this migration, the benefits in terms of safety, performance and ergonomics are the real reward.
Check if your PC is compatible with Windows 11
It is THE first step, the one that conditions everything else. Microsoft has hardened the Minimum system requirements for Windows 11, mainly for security reasons.
The easiest? Use the official Microsoft “PC Health Check” tool to instantly know if your machine is ready.
Do you manage a fleet of tens or hundreds of computers? Checking each station one by one is a mammoth job.

Preparing your computer for the migration to Windows 11
Is your PC compatible? Perfect! Before starting the big manoeuvre, a bit of preparation is required to put all the chances on your side.
- Windows 10 Update: Make sure your current system is up to date. Go in
Settings > Update & Security > Windows Update
and install all available updates. - Make space: La Upgrading Requires space. Aim for at least 20GB of free space on your main drive to be safe. It's a great time to clean up: uninstall apps you no longer use and delete junk files.
- Update your drivers: Outdated drivers can cause conflicts. Make sure your graphics, network, and motherboard drivers are up to date.
- Temporarily deactivate your antivirus: Some third-party antiviruses can sometimes interfere with the installation process. Remember to deactivate it just before you start and reactivate it right after.

Back up your data before migration

The different methods to migrate from Windows 10 to Windows 11
For the bravest, Microsoft offers three official paths: via Windows Update, with the Installation Wizard, or by creating a bootable USB key. Each has its own specificities and requires a certain level of technical comfort.
- Through Windows Update (the soft method): It is the simplest and most recommended solution. It is offered directly to you on your PC, if it is compatible. It is a guided and secure installation.
- With the Windows 11 Setup Wizard (the proactive method): Don't you want to wait for the update to be offered? Download the Setup Wizard from the Microsoft site. It will download and install Windows 11 on your machine.
- With the support creation tool (the expert method): This option allows you to create a USB stick or a bootable DVD installation. It is ideal for doing a “clean install” (clean installation from scratch) or for upgrading several computers. However, it requires effort and getting your hands dirty.
But the fourth method, still the simplest, is the _rzilient method: you give us the green light, and we take care of everything.

Common Migration Issues and Solutions
- The installation is blocked: Patience is key. If it really takes too long, check your internet connection and make sure you have enough disk space.
- A device no longer works: It is often a pilot problem. Go to the “Device Manager” to identify the hardware concerned and look for an up-to-date driver on the manufacturer's site.
- My PC is not compatible because of TPM 2.0 or Secure Boot: These options are often present but disabled in the computer's BIOS/UEFI. A reboot and a quick turn in the BIOS settings (usually by pressing F2 or Delete at startup) often activate them.

What should you do if your PC is not compatible with Windows 11?
