This computer comes with the OS already set up (Windows 11 with the latest 24H2 update) and Office installed, so you can use it right away. It has been cleaned with alcohol and the inside has been blown out with air. It's been refurbished by a computer shop, so you can be assured of its quality. It features a fast boot with a 9th generation i3 processor (officially Windows 11 compatible) and a 256GB SSD. *Please note that there may be minor scratches on the body.
