Cuidado... es buggy.... -
He encontrado solucion y he reportado esto:
Windows 11 Insider Experimental build 26340.9233 reproducibly crashes on sign-out/restart with SYSTEM_SERVICE_EXCEPTION 0x3B.
WinDbg bucket: AV_win32kfull!SetMagnificationInputTransform
Faulting function: win32kfull!SetMagnificationInputTransform+0x39
Failure hash: {527223d9-4b8b-e502-e7e6-16fc4649fd38}
The crash occurs during desktop teardown:
DestroyDesktop -> MagpDecomposeDesktop -> MagpRevokeInputTransfrom -> CancelMagnificationInputTransform -> SetMagnificationInputTransform
Workaround found and reproduced on two physical machines:
vivetool /enable /id:27829265
vivetool /enable /id:61457898
Feature 61457898 is FindMyMouse_Prototype; 27829265 is the prerequisite mouse pointer/crosshair feature.
Important: the first restart after enabling 61457898 still crashes, because the current session was apparently created with the old state. After that reboot, subsequent sign-outs and restarts no longer crash.
A/B confirmation:
vivetool /reset /id:61457898 -> crash returns on sign-out/restart.
vivetool /enable /id:61457898 -> after one crashing reboot, subsequent sign-outs/restarts are stable.
This has been reproduced on two separate physical machines. Some other physical headless machines do not reproduce the crash even with 61457898 undefined, so the feature appears to be a workaround rather than the sole trigger.
