Services needed to use Speecy

Which are the windows services needed to use Speecy. I have cleared all the services and now Speecy says it cannot run.

How to install back the services cleared ?

Thanks

I am surprised that you have decided to alter your services state without taking into consideration what services may be needed in the future. Why did you do that?

Make sure your WMI (Windows Management Instrumentation) service is running. Find it in the services list, double click it and select 'start'.
