Hello;
Support for Microsoft Windows Vista operating system; gradually cuts off. With the release of Windows 7, Microsoft; Eliminates support for Windows Vista.
As of April 13, 2010, Microsoft discontinued support for Microsoft Vista SP1; recommends users to install SP2.
There will no longer be security updates for the first version of Vista. Microsoft in a statement on the subject, urged users to upgrade to higher service packs or Windows 7.
According to my judgments Windows XP SP2 will end next July .
