The new Hardware Logo License Agreement (LLA) 2015 is now available. The new LLA has been updated to include information about the Windows 8.1 and Windows Server 2012 R2 operating systems.
You must sign the new LLA 2015 in order to upload any Hardware Certification Program submissions after Windows 8.1 and Windows Server 2012 R2 became available. The Hardware Dashboard site will block any attempted submissions after the Windows 8.1 and Windows Server 2012 R2 date unless you have signed the new LLA.
The LLA must be signed every year. If you are in the MDA program, the 2015 LLA must be signed by August 31, 2014. If not, there is not a required date by which to sign.
