xp is an operating system that uses graphical pictures (or icons) to represent applications and files. It also lets you log on and off and switch between users.
It was the first version of Windows to use the Windows NT kernel, and it introduced product activation to prevent software piracy. It was an advance over previous versions in stability, efficiency and performance.
Features
Windows XP offers a number of improvements for both users and developers. The ability to “skin” the operating system with distributable themes makes it easier for users to customize the user interface, including the start menu and task bar.
Fast user switching allows one user to maintain a separate state on the machine. This is important for applications that access hardware and that can only tolerate a single instance running at any given time.
Other improvements include support for a higher maximum number of physical processors and improved search capabilities that now categorize files by perceived type (i.e. Documents, Pictures, Music and Video). Windows XP also supports S/PDIF audio over FireWire and MPEG-2 video streams from DVD or D-VHS recorders.
In addition, a new feature called Application Compatibility Mode helps older Windows programs run better on NT/2000. This is useful for some medical devices, such as electroencephalographs that are incompatible with later versions of the operating system.
Installation
Before you begin the Windows XP installation process, make sure you have enough free disk space to install the operating system. Ideally, you should have at least 1.5 gigabytes for the installation files, plus more space for programs and other files.
Once you’ve set the BOOT menu to boot from the CD, press the
The first screen of the installation program asks you to select a language and keyboard style. After selecting a language and keyboard style, the program begins copying files to the partition.
The next screen asks you to set the workgroup name for the computer. If you’re using a corporate network, this is typically your company name. Setup then installs Start Menu items, registers system components, saves settings and removes temporary files needed by the installation process.
Maintenance
Windows XP was a major advance over previous MS-DOS based versions of Windows in both stability and security. It used the new Windows NT kernel and was the first version to implement product activation to prevent piracy.
The first step of the Windows XP setup process will ask you to press a key to boot from CD. This is important because if you don’t press a key, the computer will try to boot from the operating system that’s currently installed on your hard disk.
When you press a key, a Windows Setup screen will load. This will include a number of files and drivers that are necessary for the Windows XP repair installation to complete.
The next screen will ask you to enter the names of the users who will use Windows XP. You can enter up to five user names here. Once the necessary files and drivers are loaded, a window will appear that says Windows XP is loading. This should only take a few minutes.
Security
When Windows XP was released, critics praised its increased performance and stability (especially compared to Windows Me), more intuitive user interface, expanded multimedia capabilities, and broad hardware compatibility. It was also the first version of Microsoft’s Windows NT-based operating system to implement product activation and anti-piracy measures.
When more than one person uses a computer, it is important to minimize the risk of compromise by keeping each person’s settings and documents separate through their own computer accounts. Additionally, a password-protected account with a strong password should be created to prevent malicious software from accessing sensitive data and gaining control of the computer.
Using a firewall is another important security measure. Activating the Windows Firewall before connecting to the Internet can help to limit the risk of attack from malicious software. Additionally, it is important to apply any available patches via Windows Update. Finally, a virus scanner with up-to-date virus definitions should be used to scan all downloaded files and emails.
