It has a well installed windows 10. I was happy, as I detected, the Windows has a Windows for Linux Subsystem. With that Subsystem is a well Debian Bookworm installable on the top of the Windows. The accumulator working well. It is possible to reach Microsoft C/C++ free for this version of Windows. The Team of Windows worked well in the last years, I should consider. My original plan, to install a Debian on this system was dropped, as I detected the opportunities of this system. Many THANKs for this laptop!
