Windows Vista
Windows Vista is the 6th version of the Microsoft Windows operating system from Microsoft. It is the successor to Windows XP. While it was being made, it was called  Longhorn.  On July 28, 2005, Microsoft gave out its real name, which was Windows Vista. The original release of Windows Vista was supported until April 13, 2010; every user of Windows Vista needs to install a Service Pack 1 in order to receive security patches and support after that date, and Service Pack 2 after July 12, 2011. With Service Pack 2 installed on Windows Vista, Microsoft ended mainstream support on April 10, 2012 and then stopped supporting Windows Vista as a whole on April 11, 2017.
