Legally updated to Windows 11 Pro (Possible because it's a 9th generation CPU PC) CPUs of the 7th generation or earlier are not compatible with Windows 11 requirements. Windows 10 support has ended. Many items are listed that have been illegally upgraded to Windows 11 using a workaround, on PCs with 7th generation or earlier CPUs. Please be aware that major updates are not possible!

Internal CMOS battery replaced. Shipped after the latest updates. This computer is ready to use immediately. Only the main unit will be shipped. ※ Windows 11 PCs with 7th generation (CPU 7000 series, G4, etc.) or earlier CPUs are not eligible for major updates because they do not meet Microsoft's requirements. I think it is important to choose a PC equipped with a CPU of the 8th generation (CPU 8000 series or higher, G5, etc.) or later. Form Factor: Space-saving OS: Windows 11 Pro Thank you for viewing.
