All of these products are reaching the End of General Support phase on May 21st, 2014. This means that there will be no more maintenance updates / upgrades, security patches, bug fixes, new hardware support, or server / client / guest OS updates. These sorts of services are only provided during the General Support Phase, which is typically 5 years after a product hits general availability (GA).
