Windows 10 21H2 X-Lite (19044.2075) Phoenix Gaming Edition

3. Key Considerations Before Installation
To ensure a seamless user experience, take note of the following operational points:
1. Windows Defender is Stripped Out: To achieve maximum processing throughput, Defender is removed. If you frequently download files from third-party sources, consider using a lightweight on-demand scanner like Malwarebytes or cloud scanning tools.
2. Prepare Offline Network Drivers (LAN / Wi-Fi): Pre-download the official network drivers for your motherboard or laptop to drive D, E, or a flash drive before formatting partition C.
3. Windows Activation: The system installs in an unactivated evaluation state. You can apply your genuine digital license key or utilize the activation script provided in the Extras folder.
