Description:
----[For better reports, please attach the log file after submitting. You can find it in C:\Users\juergen\AppData\Roaming\MySQL\Workbench\log\wb.log]

see this log.
I tried tu start the Server via Start/Shutdown manually but this disn't solve the Problem.

How to repeat:
startin the wb and try to connet with user root.

Thank you for the bug report. I could not repeat either with 6.3.10 or 8.0.11 rc development release version. Check if the server is effectively running using a command line with Administrator privileges (below example with a service named mysql57)

C:\WINDOWS\system32>sc query mysql57

SERVICE_NAME: mysql57
        TYPE               : 10  WIN32_OWN_PROCESS

C:\WINDOWS\system32>net start mysql57
The MySQL57 service is starting..
The MySQL57 service was started successfully.

C:\WINDOWS\system32>sc query mysql57

SERVICE_NAME: mysql57
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 4  RUNNING
                                (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)

        CHECKPOINT         : 0x0

after you sure it is running check the connection using the mysql.exe client.
