To receive non-security updates, Extended Hotfix Support must be purchased in conjunction with or addition to Premier Support, obtained within the first 90 days following the end of the Mainstream Support phase.

Microsoft will not accept requests for warranty support, design changes, or new features during the Extended Support phase.
