Thunderbird freezes sporadically after Windows 10 April update CAUSE: unknown
Thunderbird hangs seemingly randomly after the latest Windows update. I could not end the process in task manager and needed to restart Windows to use Thunderbird. On a couple of occasions it seemed to affect the operating system as well and I could not access the start menu although I could use applications open in other windows.
Bringing out the big guns, taskkill also failed to kill the process:
PS C:\WINDOWS\system32> taskkill /f /fi "status eq not responding"
SUCCESS: The process with PID 8428 has been terminated.
SUCCESS: The process with PID 11216 has been terminated.
SUCCESS: The process with PID 14956 has been terminated.
SUCCESS: The process with PID 8264 has been terminated.
ERROR: The process with PID 15876 could not be terminated.
Reason: There is no running instance of the task.
After disabling the Lightning default add-on the problem seemed to disappear at first but reappeared after a couple of days. On that occasion the computer had just returned from sleep and was not connected to the internet.

> taskkill also failed to kill the process: That suggest something wrong at the OS level.
Please tell us, do you see the same problem if you have started Windows in safe mode?
(guess not very important to the reporter)
