How to use multiple condition in 'when' - ansible

Question

I have a Windows services start/stop playbook and services are specific to certain hosts.
I want to control start/stop services if it exists in a specific host.
I have a when to run on specific hosts but how to add and clause to check if services fromAppStopServices.yml exists before start or stop ?
Sample code
-name: service stop
hosts:all
tasks:
-name: Include app services
include_vars:
file: inventory/{{ env }}/group_vars/appstopservice.syml
-name: stop app services
win_service:
name: "{[ item }}"
state: stopped
loop: "{{ services }}"
when: inventory_hostname in group['Appservers']

You can use the win_service_info module to get the list of all win services on the target server, register the output and then query it to see if the service already exists before stopping it.

- name: service stop
hosts: all
tasks:
- name: Include app services
include_vars:
file: inventory/{{ env }}/group_vars/appstopservice.syml
# #Option 1 - using ansible win_service_info module
# - name: Get info for all installed services
# win_service_info:
# register: service_info
# Option2 - using ansible powershell module
- name: Get info for all installed services
win_powershell:
script: Get-Service
register: service_info
# # Option3 - using ansible win_shell module
# - name: Get info for all installed services
# win_shell: |
# sc queryex type=service state=all
# args:
# executable: cmd
# register: service_info
- name: stop app services
win_service:
name: "{[ item }}"
state: stopped
loop: "{{ services }}"
when:
- inventory_hostname in group['Appservers']
- service_info.stdout.find(item) != -1
