Hi,
When installing the metricbeat, it opens the notepad, not installing the service. So, How to install without this issue.
You need to run the install-service-metricbeat.ps from a Powershell shell, not double click it. Please see the Windows instructions from here: https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-installation.html and let us know if you hit any issues.
