A note from Microsoft crossed my Inbox, yesterday. We strongly encourage anyone running any version Windows Vista to upgrade to Windows 7 SP1.
Windows Vista Service Pack 1 (SP1) will reach the end of support on July 12, 2011. From that date onward, Microsoft will no longer provide support or free security updates for Windows Vista Service Pack 1 (SP1). In order to stay secure and continue support you must upgrade to Service Pack 2 (SP2).
Products no longer supported
*Note that Windows XP SP3 Mainstream Support ended April 14, 2009. Extended Support will end April 8, 2014.
Please don’t wait to migrate to Windows 7.
