With Windows 7 copies selling skyrocketing beyond Vista, it is a matter of time before Microsoft put an end to Windows’ older version. It’s not surprise to see that support to Windows XP SP2 32 bit will end by 13th July 2010, while 64 bit has longer lifeline until 18 April 2014.

Support to Windows Vista without service pack will end in about a month as well, or precisely 14-April-2010. This radical move is timely when Microsoft is still struggling to force  Vista users to upgrade to Vista SP1 which is more stable and secure.

The end of support will means no new update such as bug fix or security update will be released for these operating system. This pose security threat to the machines still running this OS version which  vulnerable to attack from virus, spyware and etc.

Microsoft is recommending every computer running older version of OS to upgrade to Windows 7, but not every computer are compatible with Windows 7 especially older computer. Upgrading from older OS version also is a pain process, when usually clean install is the best way to get your computer running efficiently.
