DLL Files and Windows Registry
You have got detailed information related to dll files. In this article, you will get a chance to know Windows Registry and how is it different than dll files. In very simple context, the windows registry is considered as a file that has the all the major part of the configuration setting and other data for the operating system of the Windows.
Although, the Windows Registry has a huge amount and variety of settings, but the configuration data of the WOW64 emulator that is very important for you to know is a list of all of the Component Object Model, commonly known as (COM) that have been registered by the Windows operating system.
The configuration data of WOW64 is shown when a Windows application program of 32-bits is run in the Windows Operating System of x64 version. Whenever this happens the WOW64 emulator points to the dll files in the Program Files Folder as expected. But, along with the dll files, the emulator also redirects some parts of the windows registry when ever requested by the application.
Windows Registry is designed in such a way that that all COM objects that are available in Windows are listed within the same registry. You just have to pay attention to the fact that a 32-bit code of the Windows Registry must be in complete isolation from 64-bit code of the Windows Registry and should be stored in two different categories of the Windows Registry.
To know the main difference between Windows Registry and DLL files, first you should know the difference between in-process server and out-process server. Libraries or dll files are in-process server as they run as a part of the same process as the application or script. In contrast with in-process server, an out-of-process server is a COM object that is usually an executable file. It executes in a different process than the application or script.
Now, let’s see how the redirection of the Windows Registry works. It works in a particular manner. Component Object Model that is a part of the Windows Registry gives a way for applications like exe files and libraries that are all dll files. Windows Registry provides them to make themselves accessible to any COM-compliant application or script. Thus, COM makes it possible to write an application that interacts with Windows directly. Thus you do not have to learn programming language like C++.
