Thinstall will list all DLL/OCX files loaded by applications loaded under it's control. Some DLLs are loaded by Windows, and some will be loaded by Thinstall. It is useful to check this list to make sure DLLs are being loaded by Thinstall where needed and the source location matches where you want the DLL to be loaded from.
DLLs will be listed as:
PRELOADED_BY_SYSTEM - Loaded by Windows before Thinstall was loaded or loaded by Windows outside of Thinstall's control. PRELOADED_MAP - Part of your base EXE SYSTEM_LOADED - Loaded by Windows after Thinstall started running. MEMORY_MAPPED_ANON - Loaded by Thinstall, DLL is isolated & invisible to Windows and Windows loaded DLLs
