Windows XP

Windows XP was the world’s most popular operating system from 2001 to 2007. It sold more than 500 million copies. It was available both individually and pre-installed on new computers.

A number of new features were introduced with XP. For example, it offers a simpler way to customize control themes. It also allows users to pin frequently used applications to the Start menu. It also has a new file system filter driver that is smaller and more stable than legacy filters. It also supports GDI+, which provides a collection of class libraries that make it easier to develop graphics for Windows programmes.

In an attempt to reduce piracy, Microsoft introduced product activation in Windows XP. This requires a user to activate their copy of Windows with Microsoft online or by telephone within a certain period of time.

Windows Vista

Windows Vista is a major upgrade to Microsoft’s flagship operating system that incorporates numerous visual and functional changes. It is reported to be more visually appealing, faster and easier to use than previous versions of Windows. New features include an Aero interface, instant search and sidebar and gadgets. It also includes Bit Locker drive encryption and user account control for increased security.

Vista includes significant improvements to system management, including a complete replacement for NTLDR and a rewritten Task Scheduler. It also provides a new device driver development model (“Windows Driver Foundation”), and transactional NTFS.

It features a new networking API that supports building SOAP-based web services in native code, reduced UAC prompts and simplified development of installation packages. It also offers improvements to hardware compatibility, allowing it to boot faster and work with a wider range of USB devices.

It is also more power efficient than its predecessors, especially on multi-core processors. This is due to the fact that it uses a task scheduler that allows it to keep open files and applications longer. It also improves the behavior of solid-state drives, reducing the frequency of write operations that wear out their storage media.
