[-- Attachment #1 --] I tried with NVMe, but nothing changed. I noticed a difference between WIN10 and WIN11, in the boot phase when it starts to load the system the CPU with WIN11 immediately increases its use. This makes me think that the problem could be related to the UEFI. I checked the UEFI options, but I did not see anything that could create problems for the CPU > Il giorno 18 apr 2025, alle ore 08:24, Oleksandr Kryvulia <shuriku@shurik.kiev.ua> ha scritto: > > Try also to change disk0_type="nvme" > > 17.04.25 20:45, Marco Orsatti: >> I actually connect to the VM via RDP (from another PC), but when I took the screenshot and looked at the CPU, there is no active connection, neither VNC nor RDP. >> >> I have tested the various editions of Win11, Pro, LTSC, IoT, and they all have the same CPU problem. >> >> >> >> >>> Marco Orsatti >>> direttore >>> I.T.
