How to use

Unpack the tower and place it on a stable, well-ventilated surface with at least a few centimeters of clearance around air intakes and exhausts. Connect a monitor, keyboard, mouse and network cable or configure Wi‑Fi as required. Power on the system and follow the Windows 11 Pro initial setup to create or connect a user account and configure updates and security settings. Install required productivity applications from trusted sources and use the built-in Device Manager and Windows Update to keep drivers and system software current. For storage management, use Windows tools to partition or expand drives if adding additional storage hardware.

Recommendations

For sustained performance, allow adequate airflow around the tower and avoid placing it in enclosed cabinets. Keep Windows 11 Pro and drivers up to date, and consider adding a second memory module or larger SSD if workloads grow beyond basic office and light content tasks. Regular backups of important data are recommended to protect against hardware faults or accidental deletion.
