Alerts being received even after deleting Grafana for Windows

Hello everyone,

I recently deployed Grafana on my Windows Server and now have to remove alerting. I have tried the following but I keep getting emails:

Stopping the Grafana Service
Renaming the GrafanaLabs folder
Stopping Prometheus
Stopping wmi_exporter
Commenting out all the smtp information in customini
And finally, deleting grafana completely

I would be really grateful for any help in this regard. The details are as below:
Grafana Version: 9.2.2
Windows 10
