Which is why I included the web page and quoted it.
Those are Microsoft's words - not mine. It is fairly clear..
Something you read in an article should be compared with what Microsoft
themselves present on the pages above and below this point in this thread.
Microsoft defines when they discontinue support for their products, no one
else. =)
Windows Vista is the "next version of the product" in this case.
"... Mainstream support will end two years after the next version of this
product is released ..."
So the day Windows Vista is released - you have two years from then.
There is no ambiguity in that.
More information:
http://www.microsoft.com/windows/lifecycle/default.mspx
and
http://support.microsoft.com/gp/lifepolicy
(Those are different Microsoft sites than I quoted earlier)
The last one clearly states:
"Microsoft will offer Mainstream support for either a minimum of 5 years
from the date of a product's general availability, or for 2 years after
the successor product (N+1) is released, whichever is longer."
In that case the 'successor product' would be Windows Vista (For Windows
XP anyway..)
Now - where things get a little gray is support for what "revision" of
Windows XP.. And that even gets clarified on Microsoft web pages. By
revision - I mean "Service Pack Level" - not flavors (like Windows XP
Home, Professional, Tablet, etc..)
a.. Security Hotfix Support for Windows XP with no service packs installed
will be provided through September 30, 2004.
a.. Windows XP Service Pack 1 (SP1) will be supported in accordance with
the Microsoft Support Lifecycle policy until October 10, 2006.
a.. Windows XP Service Pack 2 (SP2) will be supported in accordance with
the Microsoft Support Lifecycle policy until either 12 months after the
next service pack releases or at the end of the product's support
lifecycle, whichever comes first.
This web page has a table of the products and their service pack life
cycles:
http://support.microsoft.com/gp/lifesupsps#Windows
Remember - the latter is "service pack support" - not the "product
support" life cycle. While there are overlaps - they are not the same
thing. Windows XP is still supported for two years after the release of
Vista to the public.
