We've updated all active errata filters for the Windows Hardware Certification Kit (HCK). All active errata that weren't fixed in the test kit are now extended until 12/31/2014. We'll reevaluate all active errata again about 3 months before the new expiration dates. We'll either retire errata or extend the expiration date again, depending on whether fixes are in place for the test issues.
A few errata are set to expire between now and 12/31/2013 by design for delayed enforcement reasons or because fixes were implemented into the next HCK release. Those errata won't be extended again.
