Windows Internal Database Overview
Applies To: Windows Server 2008 R2
Windows Internal Database is a relational data store used by the following applications and services.
Active Directory Rights Management Services (AD RMS)
Windows Server Update Services
Windows System Resource Manager
These applications and services share a single instance of the data store.
You typically do not need to install Windows Internal Database. It is installed by the first application or service that requires it.
Because multiple applications and services use the same instance of Windows Internal Database, removing these applications and services does not remove the data store. If you have removed all applications and services that use Windows Internal Database, you can then remove it by using the Server Manager Remove Features Wizard.
