If you have a problem with the Windows Mobile Device Center (for instance your mobile device doesn't seem to be detected and cannot connect), it can be necessary to restart the Windows Mobile Device Center. But it is generally not necessary to reboot your computer. You can simply restart the Windows Movile Device Center processes.
You can do the following operations:
- Disconnect your mobile device
- Kill wmdhost.exe
- Kill wmdc.exe
- Restart the Windows Mobile Device Center (from the Control Panel for instance)
