OS Files and Folders
As mentioned earlier, one of the characteristics of an OS is that it organizes data stored on the hard drive This includes organization of the vital OS files themselves Each modern version of Windows organizes essential files and folders in a similar fashion:
All have a primary system folder for storing most Windows internal tools and files All use Registry files that keep track of all the hardware loaded and the drivers that enable you to use that hardware Finally, every version has a virtual memory file, enabling more robust access to programs and utilities
Let s take a more detailed look at these aspects of Microsoft Windows
System Folder
Evidently, you can t simply go around calling the folder where Windows installs the operating system files The folder where Windows installs the operating system files Instead, SystemRoot is the tech name given to the folder in which the latest version of Windows is installed The SystemRoot folder for Windows 2000 is named WINNT by default Windows XP calls the SystemRoot folder WINDOWS by default Windows 2000 and Windows XP can be installed onto any primary, active partition, not just the C: drive It s handy to know about SystemRoot You ll find it cropping up in many other tech publications, and it can also be specified when adjusting certain Windows settings to make sure that they work under all circumstances When used as part of a Windows configuration setting, the term is often written as %SystemRoot% (the percent signs indicating that the SystemRoot is a variable parameter)
Travel Advisory
Here s a handy trick If you don t know where Windows was installed on a particular system, go to a command prompt, type cd %systemroot%, and press the ENTER key The prompt will change focus to the folder in which the Windows OS files are stored

Registry
The Registry is a database that stores everything about your PC, including information on all the hardware in the PC, network information, user preferences, file types, and virtually anything else you might run into with Windows Almost any form of configuration done to a Windows system involves editing the Registry In fact, the Control Panel applets that you know and love are simply user-friendly Registry editing tools The Registry in Windows 2000/XP is composed of many files The numerous Registry files (called hives) are stored in the \%SystemRoot%\System32\config folder Accessing the Registry The main way to access the Registry is through the Control Panel You can get to the Control Panel in several ways Double-click the My Computer icon on your desktop, and double-click the Control Panel icon Alternatively, in XP, choose Start | Control Panel, or in 2000 choose Settings | Control Panel Figure 1516 shows the Windows XP Professional Control Panel sporting the Classic View (preferred by four out of five techs worldwide) You
