Tuesday marked an end of an era for Microsoft and Microsoft users alike, Windows XP era. After twelve years, Microsoft has decided to end providing security updates and support for the Windows XP line. The people most affected by this are businesses and federal agencies. Windows XP is considered to be the best operating system that Microsoft has produced since it launched on October 25, 2001. Microsoft has released multiple successors throughout the years: first was the loathed Windows Vista, quickly followed by Windows 7, and now Windows 8.
