An Introduction to Windows 2000 Professional




Reliability

Windows 2000 Professional is up to 30 percent faster and, according to National Software Testing Labs (NSTL) tests, 13 times more reliable than Windows 98. The operating system is the most reliable version of Windows ever produced.
Memory conflicts and missing or altered system files caused many of the system crashes prior to Windows 2000. To put an end to these problems, Microsoft changed Windows 2000 memory management to reduce the chance that software applications will interfere with one another. In addition, Windows 2000 includes a built-in safeguard called Windows File Protection. This feature helps prevent critical operating system files from being deleted or altered by users or applications. Industry studies show that as much as 80 percent of system failures can be traced to human errors or flawed processes. If a system file should be changed or deleted, Windows File Protection can detect the change, retrieve a correct version of the file from a cache, and restore it to the system file folder. The end user never knows the repairs have been made because Windows 2000 just keeps running ( (1)Windows).
The following is a list of improvements in Windows 2000. It should be noted that this covers the entire Windows 2000 family (Server, Advanced Server, and Professional).
• Improved Internal Architecture: Windows 2000 includes new features designed to protect your system, such as preventing new software installations from replacing essential system files or stopping applications from writing into the kernel of the OS. This greatly reduces many sources of operating system corruption and failure.



• Fast Recovery from System Failure: If your system does fail, Windows 2000 includes an integrated set of features that speed recovery.
• Improved Code with Developer Tools: Microsoft provided third-party developers with tools and programs to improve the quality of their drivers, system level programs, and application software. These enhancements make it easier for independent software vendors to write dependable code for Windows 2000.
• Reduced Reboot Scenarios: Microsoft has greatly reduced the number of operations requiring a system reboot in almost every category of OS functionality: file system maintenance, hardware installation and maintenance, networking and communications, memory management, software installation, and performance tuning (Increasing).
NSTL collected uptime data in the real-world environment of several customer sites and concluded that the average system uptime between failures of Windows 2000 Professional is 13 times more than that of Windows 98 and three times more than that of Windows NT Workstation 4.0. The following graph shows results of the test.







Another test conducted by ZD labs showed that over a 90 day period Windows 2000 Professional did not fail, while Windows 98 and Windows NT did.


IT managers have stated unequivocally that Windows 2000 Professional provides far superior performance and reliability compared to Windows 95. The reported performance disparity between Windows 98 Second Edition, Windows NT Workstation and Windows 2000 Professional has not been as extreme as with Windows 95, but significant improvements do exist. A 300 percent increase in hardware support, significant improvements in hardware utilization and the long-awaited combination of stability and user friendliness for laptop systems are just a few examples ((2) Windows).
Mobile Use
Windows 2000 Professional is quickly becoming the operating system of choice by mobile users. One big reason is that this latest version of Windows includes a number of notebook-friendly features, including communications tools for dial-up networking.


Windows 2000 Professional contains everything most users need. Adding third-party communications software increases cost and reduces consistency of setup, because different employees may use different types of software or Internet Service Providers (ISP). Also, training is less expensive if all dial-up communications use the same features. Cost and consistency are the two of the biggest benefits within the Windows environment. Despite these benefits, setting up the operating system to dial into a corporate network, virtual private network, or even an Internet service provider isn\'t easy for everyone (Mobile)
Because mobile computing is essential to so many businesses, Windows 2000 Professional includes features designed to make using notebook computers simpler and more efficient. In short, running Windows 2000 Professional on a notebook computer, can enhance your mobile computing experience in four major ways ((3) Windows):
• Extends Notebook Capabilities
• Allows You to Work Anytime and Anywhere
• Provides a High Level of Security
• Supports Advanced Hardware
