Windows Registry - XP Operating System
Welcome to our Windows XP tutorial, this tutorial is aimed at new Windows XP users that are unfamiliar with the operating system. In this first part of the tutorial we will have a look at the Windows desktop and introduce you to icons and the taskbar.
About Windows XP
Windows XP is a line of operating systems produced by Microsoft for use on personal computers running x86 and IA-64 processors, including home and business desktops, laptops, and media centers. The name "XP" stands for "experience". Windows XP is the successor to Windows 2000 Professional and Windows Me, and is the first consumer-oriented operating system produced by Microsoft to be built on the Windows NT kernel and architecture. Windows XP was released on 25 October 2001, and more than 400 million copies were in use in January 2006, according to an estimate in that month by an IDC analyst. It was replaced by Windows Vista, which was published in volume license customers on 8 November 2006, and worldwide to the general public on 30 January 2007. Direct OEM and retail sales of Windows XP has ceased on 30 June 2008, but it is still possible to obtain Windows XP from System Builders (smaller OEMs who sell assembled computers) until 31 July 2009 or by purchasing Windows Vista Ultimate or Business and then downgrading to Windows XP.
Sometimes using the System Restore feature in Windows can fix problems, so for the less technically experienced this might be the more painless route to go if the above scanning solutions don't work and you don't want to play around with the registry. This information is recorded in the registry and needs to be cleaned with a windows registry cleaner regularly. However sometimes the programs you install can alter your windows registry in such a way that the windows registry recovery program won't be able to fix.
Over time your windows registry can accumulate junk files from the constant installation of newer programs and removal of obsolete ones.
