// Since all service information can be obtained,
// Query whether the process is a service based on the process ID, and obtain the service name and other operations as required.

How to obtain the service ID of a windows system

Right-click my computer and choose Properties-the computer name is displayed on it!

In Windows, how does one enumerate all system services in the command line?

Net start
----------------------------
I only saw you say "whether there are other commands". I didn't expect you to say SC.
Very easy!

REM ============================================== ===
REM startup status is RUNNING
@ Echo off
SC query | find "DISPLAY_NAME"> 1.txt
For/f "tokens = 2, * delims =" % I in (1.txt) do echo % I % j
Del 1.txt
Pause
REM ============================================== ===

If you want to list all statuses, replace them with the following
SC query state = all | find "DISPLAY_NAME"
