Short Answer
To install Windows on a newly built PC, create official installation media, boot from USB, install the Home or Pro edition you plan to activate, connect to the internet, install drivers, and enter the matching product key in Activation settings.
- Back up any existing drive before formatting.
- Install the edition that matches the key.
- Keep the order email and activation screenshot if support is needed.
Step 1: Prepare the USB Installer
Use Windows installation media and a USB drive. Confirm whether your new PC meets Windows 11 requirements before choosing Windows 11.
Step 2: Choose the Correct Edition
Select Home or Pro based on the key and features you need. This choice matters because activation depends on edition match.
Step 3: Install Drivers and Activate
After installation, connect to the internet, install chipset/network/GPU drivers, and activate Windows from Settings. If activation fails, save the exact code before reinstalling.
