If a manifest exists, Windows uses the information in the manifest to populate the activation context. If an application creates a process by calling CreateProcess, Windows checks for the existence of an application manifest. For more information about the activation context functions and structures, see the Activation Context Reference.īeginning with Windows XP, activation context functions enable Windows to use information in manifests to create version-named objects. The activation functions can redirect the binding of an application to version-named objects that specify particular DLL versions, window classes, COM servers, type libraries, and interfaces. The activation context functions use, create, activate, and deactivate activation contexts.
One section of the activation context may contain DLL redirection information which is used by the DLL loader another section may contain COM server information. Activation contexts are data structures in memory containing information that the system can use to redirect an application to load a particular DLL version, COM object instance, or custom window version.
