Step 1: Downloading and Installing Windows 11

First things first — you’ll need to grab the official Windows 11 installation files directly from Microsoft. Here’s how to get everything set up:

  1. Open your browser and navigate to https://www.microsoft.com/en-us/software-download/windows11
  2. Once there, choose how you want to proceed — either select “Upgrade Now” for an in-place upgrade or “Create Installation Media” if you prefer a clean setup using a USB drive or DVD
  3. Follow the on-screen prompts to complete the download and launch the installation wizard

Tip: The “Create Installation Media” option is ideal if you’re setting up Windows 11 on multiple machines or performing a fresh install from scratch.
