Thank you for response, I take note of the suggestion, but is no guarantee that it is going to work, and to upgrade to the newest version is not currently a option. The symptoms is suggesting some other problem as their is two other windows 11 systems running with no problems (not connected to outside).
I suspect that it has something to do that some of systems being on the domain and that some group policies updates or lack their off is causing the problem. The worst initially was Windows auto update and restart in non working hours and these machines is capturing and monitoring 24/7 Postponing system updates reduced problems, but I believe Teams and Office being online accounts might result in unforeseen problems.
My suggestion to my client is to remove these systems from domain and or internet as these machines not connected is not being affected.
