Step 1. Find out the Service Name

To do this, go in to services and double click on the service which has stuck.  Make a note of the “Service Name”.

Step 2. Find out the PID of the service

Open an elevated command prompt and type in:

sc queryex servicename

(where servicename is the name of the service you obtained from Step 1.)

Make note of the PID

Step 3. Kill the PID

From the same command prompt type in:

taskkill /f /pid [PID]

Where [PID] is the service number.

If it is successful you should receive the following message:

SUCCESS: The process with PID XXXX has been terminated.
