Check what update rollup is installed on Microsoft Dynamics CRM

To navigate to the about page of CRM, click on File -> Help -> About Microsoft Dynamics CRM
CRM Deployment Manager
Open Microsoft Dynamics CRM Deployment manager, and select Servers, you will see the name, role and version of the server.
