Over the past six months, we`ve found that XP runs well on a Pentium III-500 with 128MB of RAM. However, as expected, increasing disk speed and memory makes a significant difference in XP performance. For best results, choose a hard drive that spins at 7,200 or 10,000 rpm instead of 5,400 rpm, a fast processor (400, 600 or 800 MHz instead of 233 or 266 MHz) and generous amounts of RAM (256 or 512 MB instead of 64 or 128 MB). You should probably avoid 8-bit or 16-bit ISA I/O cards or older for audio and video, and we also recommend PCI or AGP graphics cards to take advantage of XP`s nifty video effects, such as menus that fade in and out and shadows on window and desktop icons. Your computer must meet the minimum system requirements to run the Windows XP Professional operating system. For example, Windows XP Professional must have a minimum amount of memory and disk space. Additional features require the installation of a CD or DVD drive, video card, and sound card. Computers that do not have prerequisites installed must be upgraded or replaced before installing XP Professional. For more information, see the Drive_Letter log file:windowssvcpack.log.
The Start menu was fundamentally revised for the first time in XP, moving to a two-column layout with the ability to list, pin, and view frequently used apps, recently opened documents, and the traditional cascading All Programs menu. The taskbar can now group windows opened by a single application into a taskbar button, with a context menu listing each window. By default, the notification area also hides “inactive” icons. A common task list has been added and the Windows Explorer sidebar has been updated to use a new task-based theme with lists of common actions. The tasks displayed are contextually relevant to the content type of a folder (for example, a music announcements folder offers to play all the files in the folder or burn them to a CD).  Microsoft`s minimum system requirements for Windows XP are a 233 MHz processor, 64 MB RAM, 1.5 GB of available hard disk space, and an SVGA-compatible graphics card. UITS has found that computers that do not exceed these requirements perform Windows XP poorly or not at all. UITS strongly recommends that any system running XP have a processor faster than 400 MHz and at least 256 MB of RAM. Windows XP seems to have two system requirements, which is confusing for many potential upgraders. Microsoft has issued a minimum requirement for performance and hardware capabilities, and if you don`t meet that requirement, XP simply refuses to install. But the company also issued a minimal recommendation — a much stricter set of specifications that should lead to optimal performance. www.microsoft.com/windows/internet-explorer/default.aspx So, which set is best for you? We`ve spent the last six months playing with different hardware configurations and found that you only have to worry about the minimum system requirements.
You can run XP on any system that meets or exceeds these specifications, namely a 233 MHz processor with 64 MB of RAM, 1.5 GB of free hard disk space, a screen resolution of 800 x 600, and a CD-ROM drive. However, if you want XP to work quickly and stably, the minimum recommendation is the goal you should aim for. Windows XP is a major version of Microsoft`s Windows NT operating system. It was released in production on August 24, 2001 and later retailed on October 25, 2001. It is an in-place upgrade of its predecessors, Windows 2000 for high-end and business users and Windows Millennium Edition for home users, which are available to all devices running Windows NT 4.0, Windows 98, Windows 2000, and Windows Millennium Edition that meet the new system requirements for Windows XP. 947311 Disk space requirements for Windows XP Service Pack 3 Of course, there`s a good chance your existing hardware meets the minimum requirements for both operating systems: a 1 GHz or faster processor, 1 GB of RAM (2 GB for 64-bit), 16 GB of disk space (20 GB for 64-bit), and a DirectX 9 graphics device with WDDM 1.0 or higher. And if you`re an IT professional with decision-making power in a company that continues to use XP, you should be fired.
