Microsoft Windows is a series of graphical interface operating systems developed, marketed, and sold by Microsoft.
Microsoft introduced an operating environment named Windows on November 20, 1985 as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUI). Microsoft Windows came to dominate the world's personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984.

Windows Vista is an operating system by Microsoft for use on personal computers, including home and business desktops, laptops, tablet PCs, and media center PCs. Prior to its announcement on July 22, 2005, Windows Vista was known by its codename "Longhorn". Development was completed on November 8, 2006, and over the following three months, it was released in stages to computer hardware and software manufacturers, business customers and retail channels. On January 30, 2007, it was released worldwide and was made available for purchase and download from Microsoft's website. The release of Windows Vista came more than five years after the introduction of its predecessor, Windows XP, the longest time span between successive releases of Microsoft Windows desktop operating systems. It was succeeded by Windows 7, which was released to manufacturing on July 22, 2009 and released worldwide for retail on October 22, 2009.
In computer science and engineering, computer architecture is a set of disciplines that describes a computer system by specifying its parts and their relations.
For example, at a high level, computer architecture may be concerned with how the central processing unit (CPU) acts and how it uses computer memory. Some fashionable (2011) computer architectures include cluster computing and Non-Uniform Memory Access.
System Restore is a feature in Microsoft Windows that allows the user to revert their computer's state (including system files, installed applications, Windows Registry, and system settings) to that of a previous point in time, which can be used to recover from system malfunctions or other problems. First included in Windows ME, it has since been included in all following desktop versions of Windows released since, excluding the Windows Server
In prior Windows versions it was based on a file filter that watched changes for a certain set of file extensions, and then copied files before they were overwritten. An updated version of System Restore introduced by Windows Vista uses the Shadow Copy service as a backend (allowing block-level changes in files located in any directory on the volume to be monitored and backed up regardless of their location.) and allows System Restore to be used from the Windows Recovery Environment in case the Windows installation no longer boots at all.
Windows Vista (formerly codenamed Longhorn) has many new features compared with previous Microsoft Windows versions, covering most aspects of the operating system.

Bundling of Microsoft Windows is when computers have been installed with Microsoft Windows before purchase. Microsoft encourages original equipment manufacturers (OEMs) of personal computers to include Windows licenses with their products, and agreements between Microsoft and OEMs have undergone antitrust scrutiny. Users opposed to the bundling of Microsoft Windows have sought refunds for Windows licenses, and although some customers have successfully obtained payments (in some cases after litigation or lengthy negotiations), others have been less successful.
A search box or search field is a common GUI element used in computer programs, such as file managers or web browsers, and on web sites. A search box is usually a single-line text box with the dedicated function of accepting user input to be searched for in a database. Search boxes on web pages are usually used to allow users to enter a query to be submitted to a Web search engine server-side script, where an index database is queried for entries that contain one or more of the user's keywords.
Search boxes are commonly accompanied by a search button (sometime indicated only by a magnifying glass symbol) to submit the search. However, the search button may be omitted as the user may press the enter key to submit the search, or the search may be sent automatically to present the user with real-time results.
