1. Prepare Your PC for Windows 11 Installation

Before installing Windows 11, it’s important to back up your data and ensure your system meets requirements.

• List your applications: Note down the programs and product keys you’ll need to reinstall later.

• Check system requirements: Windows 11 needs UEFI with Secure Boot, TPM 2.0, 4 GB RAM, and at least 64 GB storage.

• Download essential drivers: Get Wi-Fi, Ethernet, and graphics drivers in advance to stay connected after installation.
