Kill Windows Services that Hang on "Stopping"

Step-by-step

1. In the command prompt, execute sc queryex w32time. The service name is w32time for example. The information is here:
   

   SERVICE_NAME: w32time
           TYPE               : 20  WIN32_SHARE_PROCESS
           STATE              : 4  RUNNING
                                   (STOPPABLE, NOT_PAUSABLE, ACCEPTS_SHUTDOWN)
           WIN32_EXIT_CODE    : 0  (0x0)
           SERVICE_EXIT_CODE  : 0  (0x0)
           CHECKPOINT         : 0x0
           WAIT_HINT          : 0x0
           PID                : 1352
           FLAGS              :
   

   The PID of the service is 1352. We will kill the service by this PID.
   
2. In the command prompt, try to execute taskkill /PID 1352 first. If the service is alive, execute taskkill /PID 1352 /F. The /F flag means forcefully terminating the process.
