Well these tips are really useful and comes handy at times. I think you should bookmark both of these pages for future reference. My company hardware guys told me that the whole co-operate need to shift to Windows Vista as Microsoft is ending support for Windows XP by Jan 31st 2008. Unless the company guys push my system to windows Vista , I think i am gonna stick with Win XP coz its my comfort zone !!!

Welcome technobuzz
This is what I found on http://en.wikipedia.org/wiki/Windows_XP#Support_lifecycle
“”Support lifecycle
Mainstream support for Windows XP Service Pack 2 will end on April 4, 2009, four years after its general availability[30]. As per Microsoft’s posted timetable, the company will stop licensing Windows XP to OEMs and terminate retail sales of the operating system January 31, 2008, 12 months after the release of Windows Vista.
Windows XP will begin its “Extended Support” period that will last for 5 years until 2014.[31] First generation Windows XP (without Service Pack 2) is no longer supported; Microsoft ended the support for Windows XP RTM on September 30, 2004 and Windows XP Service Pack 1 and 1a on October 10, 2006.[32]“”.
I am sure your IT dept mis-understood something as always is the case with anything Microsoft.
