Dynamic link libraries (DLLs) The main limitation of static libraries is that they are, for lack of a better term, static. They are created in one place and accessed by one program at a time. With DLLs, Microsoft invented a new way for libraries to be dynamically accessed by multiple processes at the same time. With a DLL, the same piece of information can be accessed by multiple portions of the program. So, if your program were accessing a particu- lar piece of itself that needed to be accessed by another portion of the program, if that piece of information was in a static library, the other portion of the program would not be able to access this information. By contrast, a dynamic link library will happily let this happen. At the enterprise level, you are most concerned about CompTIA Exams DLLs for two very important reasons. The first is that you are concerned about application deployment (where your applications exist on your server). The second reason you are concerned about DLLs is that they de?ne the version of the program that your software is using. The primary advantage of Application Virtualization is that it virtually (pun intended) elimi- nates the concept of ?DLL hell,?meaning the inability to find system libraries, or correct versions of system libraries, for certain programs. Because SoftGrid is designed in such a way that deployment throughout the enterprise can be universal, if an application is deployed, you can organize it in such a way that it is deployed the same throughout the entire enterprise. The Microsoft .msi ?le extension stands for ?Microsoft Installer.?MSI ?les comprise execut -able code that contains installation wrappers for programs installed on Microsoft platforms that include the program base code, its required libraries, and other information required for the program to function. Typically, this type of ?le is manipulated and shared by the server as an application install ?le for clients or hosts. Additionally, in traditional Group Policy deployment, MSI ?les are used to assign or publish applications throughout the network based on prede?ned policies set by the administrator. For virtualization, it

As we head closer to Windows7 launch, expect to see more features being ported for Vista and XP till we can try them on actual Windows7 operating system. Improving existing features may seem more important to people who understand the existing features and know how they can be improved, but the majority of people who will be purchasing the new operating system don't know anything about that, and if the only thing that is improved is things that the average user doesn't notice, the average user isn't going to see any reason to upgrade to the new OS. Faster boot up time, standby resume, launching common applications, reducing the time it takes for the OS to recognize a reinserted USB device, particularly a flash drive, faster playback of DVD movies, improved response and memory usage of the desktop window manager including taskbar and start menu, reducing the operating system's overall footprint, reducing freezes and hangs.
The new Windows 7 features will help determine if the operating system is a success or if it follows in the footsteps of its predecessor, Windows Vista. But one thing that's not new is the operating system kernel: Windows 7 is based on the Vista kernel, instead of an entirely new one.
