Before doing anything, it's essential to check that your computer won't fall short. Installing the system on a PC that doesn't meet the minimum requirements can lead to stability problems. To be sure, the best thing to do is use the PC Health Check application , which will tell you in a moment if your hardware is compatible.

There are two critical points that often cause problems: TPM 2.0 and Secure Boot . If the tool tells you they're not active, don't worry, as usually all you need to do is enter your motherboard's BIOS/UEFI, find the Security or Boot tabs, and manually enable these features for the installer to proceed.

The fast track: Windows Update

This is the simplest method and the one recommended by Microsoft. Just go to Settings, Update & Security , and click the Check for updates button. If your PC is eligible and Microsoft has already validated your hardware, you'll see a banner inviting you to download and install the new system.

Once you accept the license terms, the process will be automatic. Your computer will download the data and, when finished, will prompt you to restart your device . Note that your PC will restart several times; this is perfectly normal, and you should not turn it off until you see the login screen.

The forced path: Installation Wizard

If you know your PC is compatible but Windows Update is playing dumb and not offering the version, you can use the Windows 11 Setup Assistant . It's a small application that you download from the official Microsoft website and that basically forces the system to start the migration.

When you run it, the program will re-validate your components. If everything is in order, simply click Accept and Install . This method is ideal for those who don't want to wait for the gradual rollout of updates and prefer to have the latest features installed in just a few minutes.

The advanced option: Installation media and ISO

For those who prefer complete control or want to perform a clean installation, installation media is available. You can create a bootable USB drive with the official ISO image. There are two ways to use it: running the setup.exe file while in Windows 10 to upgrade, or booting your PC from the USB drive for a clean installation.
