1. Check in Windows Services
i. Press Win + R, type services.msc, and press Enter.
ii. Look for a service name like:
SQL Server Reporting Services (MSSQLSERVER) for a default instance
SQL Server Reporting Services (<InstanceName>) for named instances
iii. If you see it and its status is “Running,” SSRS is installed and active.

2. Check in SQL Server Installation Center
i. Open the SQL Server Installation Center (search for “SQL Server Installation Center” in Start).
ii. Click Tools -> Installed SQL Server features discovery report.
iii. This will open an HTML report showing installed features.
iv. Look for Reporting Services in the list.

3. Check from a Web Browser (if configured)
i. If SSRS is configured, you can open its web portal:
Default URL: http://<ServerName>/Reports or http://<ServerName>/Reports/Pages/Folder.aspx
Or for the Report Server Web Service: http://<ServerName>/ReportServer
ii. If you get a SSRS web interface instead of an error, it’s installed and running.
