The AppInit DLLs are loaded into the process during User32's initialization—that is, while its DllMain function is executing. Developers are explicitly told not to load other DLLs within a DllMain. It can lead to deadlocks and out-of-order loads, which can lead to application crashes. And yet here, the AppInit DLL "feature" does exactly.

On Vista and later, the AppInit DLLs need to be signed, tho the registry value RequireSignedAppInit_DLLs can be set to 0 which disables this requirement. It's more correct to say that the AppInit_DLL dll is loaded by user32.dll when user32.dll itself is loaded, and that can happen dynamically (delay-load or manual load).
The AppInit_DLLs value can hold a space separated list of DLLs with full paths, which will be loaded into the process's address space. This is done by using the LoadLibrary() function call during the DLL_PROCESS_ATTACH process of user32.dll; the user32.dll has a special code that traverses through the DLLs and loads them, so this functionality.

The AppInit_DLLs infrastructure provides an easy way to hook system APIs by allowing custom DLLs to be loaded into the address space of every interactive application. Applications and malicious software both use AppInit DLLs for the same basic reason, which is to hook APIs; after the custom DLL is loaded, it can hook a well-known system API and.
