You can use the Dependency Walker utility to see all the DLL files that a Windows application requires (or depends on).
You can download 32-bit (x86) or 64-bit (x64) versions of the application from the linked website.
But, in general, you will depend on many system DLLs that come with Windows that you should not redistribute yourself . Feel free to ignore them whenever they appear on the list. The user will either have (if she has the appropriate version of Windows) or will not have them (if they have an earlier version of Windows that did not provide the functionality contained in these libraries), in which case your application will not work. You will need to write backup code to handle these cases. Attempting to redistribute system DLLs will not work. You cannot add functionality to earlier versions of Windows by simply pasting the DLLs into the Windows folder.
