The ActiveX Installer (AxInstSV) service provides User Account Control validation for the installation of ActiveX controls from the Internet, and it enables managing the ActiveX control installation that is based on Group Policy settings. This service's startup type is Manual, so it will start when requested by an application. If this service is disabled, the installation of ActiveX controls will behave according to the default browser settings. When the ActiveX Installer service is started in its default configuration, it logs on by using the Local System account.

This service is included in all versions of Windows 7, but it is not included in Windows Server 2008 R2.
