Sigh. The headline of this old news is absolutely misleading.
Something like "Vista now in extended support phase" would have been more appropriate.
Until a few weeks ago, MS planned to supply extended support (i.e. security fixes) only to the business flavours of Vista. The home versions, including Home Premium, Ultimate would then have been no longer supplied with security patches.
Fortunately, MS changed their mind recently. And while they were at it, they gave the home versions of "7" the same extended support period as with the business versions.
