What is advertising?
Installing the interfaces required for loading and launching the application are presented to the user or other applications is called as Advertising.
The two types of advertising are assigning and publishing. An application appears installed to a user when that application is assigned to the user. The Start menu contains the appropriate shortcuts, icons are displayed, files are associated with the application, and registry entries reflect the application’s installation. When the user tries to open an assigned application it is installed upon demand.
The installer registers COM class information for assigned applications beginning with the Windows 2000 and Windows XP systems. This enables the installer to install the application upon the creation of an instance of an advertised class.
Why to advertise?
As Advertising only installs required interfaces, it doesn’t install the application unless demanded therefore it helps in saving disk space.
When advertised application gets installed?
If a user or application activates an advertised interface the installer then proceeds to install the necessary components as described in Installation-On-Demand.
