Windows Update
Windows Update is the simplest option when upgrading an eligible existing Windows installation. You can open Windows Settings and check for available updates.
If your PC is eligible and the upgrade has been made available for your device, Windows Update can guide you through the upgrade process.
Windows 11 Installation Assistant
The Installation Assistant is designed for upgrading the PC you are currently using. Microsoft states that the tool requires Windows 10 version 2004 or later and at least 9 GB of available disk space for the download. It currently supports x64 PCs rather than Arm-based PCs.
The general process is:

Your computer may restart several times during the installation.
Windows 11 Media Creation Tool
The Media Creation Tool can create installation media for Windows 11. This is useful when you want to reinstall Windows, prepare a bootable USB drive, or install Windows 11 on another compatible PC.
Microsoft recommends using a blank USB flash drive with at least 8 GB of available capacity when creating USB installation media. Existing content on the USB drive will be deleted during the process.
Windows 11 ISO Download
Microsoft also provides Windows 11 ISO files. An ISO can be used to create installation media or mount the image directly for an upgrade.
The official Windows 11 download page currently provides a multi-edition ISO for x64 devices. Microsoft also provides an Arm64 ISO option for supported Arm-based hardware.

| Storage | 64 GB or larger |
| System Firmware | UEFI, Secure Boot capable |
| TPM | TPM 2.0 |
| Graphics | DirectX 12 compatible with WDDM 2.0 driver |
| Display | HD 720p display larger than 9 inches |

Older computers configured with legacy BIOS settings may need firmware configuration changes, but compatibility should be checked before making changes.
How to Check Windows 11 Compatibility
Microsoft provides the PC Health Check application to help users determine whether their computer meets Windows 11 requirements. The tool can identify compatibility issues and show which requirements may not currently be satisfied.
Checking compatibility before starting an installation can help prevent unexpected problems.

For an upgrade, launch the Windows 11 setup from the existing operating system and follow the instructions.
For a clean installation, boot the compatible computer from the Windows 11 installation USB or DVD. Select the appropriate installation options and follow the setup wizard.
A clean installation can remove existing applications, settings, and files from the selected system drive, so a complete backup should be created first.
How to Upgrade Windows 10 to Windows 11

Windows 11 Home and Windows 11 Pro are different editions intended for different types of users.
Windows 11 Home is designed primarily for general consumers and everyday computing.
Windows 11 Pro includes additional management, security, virtualization, and business-oriented capabilities.
The edition installed or activated on a computer depends on the applicable license and product key. Users should choose an edition that matches their legitimate license.
Windows 11 Activation and Licensing
Windows 11 activation verifies that the installed copy is properly licensed. Depending on how Windows was obtained, activation can be associated with a digital license or product key.
Avoid unofficial activation tools, modified ISO files, and license bypass utilities. These sources can create security, update, compatibility, and licensing problems.

Before installing, verify that the ISO or installation media came from a trusted source. Microsoft also provides instructions for verifying ISO integrity using SHA-256 hashes.
Windows 11 Download for Gaming
Windows 11 supports modern PC gaming features and technologies. Gaming performance, however, depends heavily on the processor, graphics card, RAM, storage, drivers, and individual game requirements.
