Windows command for CPU utilization % for particular service

Yes, it's possible.

This wmic command prints the CPU usage for all processes. Then you can pipe it to findstr to filter for a particular process (using the flag /c:<process name>).

wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime

Do help findstr and help find from the command line to see more ways you can filter the list.

For example:

C:\> wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime | findstr /i /c:chrome
chrome                  24
chrome#1                0
chrome#2                0
chrome#3                0
