since this upgrade, I can see an error message dialog box immediately after the lock screen, it's way too short to be readable. How can I investigate on it ? thks
There's pause screen on keyboard and the error should be listed in event viewer, it might be to fast for pause screen. I would boot two times and check time on pc and then look at event viewer for errors with that time.
yes its too fast even to hit "pause" key, event viewer says svchost.exe is involved, I remembered F-Secure AV updated recently, so I uninstalled it, rebooted: no more error thank you
Thank you for the reply and the thanks, glad you noticed the AV update, or you would be tracking the error down, and you know SVC host is a large group.
