Windows 8.1 Preview ready for hardware developers
Windows 8.1 takes another critical step with the public availability of Windows 8.1 Preview. You can use Windows 8.1 Preview to test your devices for Windows 8.1 certification by using the new Windows Hardware Certification Kit (HCK) for Windows 8.1.
Download the kits, bits, and tools that you need to develop, assess, and certify hardware and drivers with Windows 8.1 Preview. Enjoy new capabilities and technologies that help you design and develop devices with the latest advances in displays, battery life, and performance.
With Windows 8.1 Preview, you can enrich the feel and functionality of your devices through elements like clearer display resolution; faster boot, resume, and app launch times; easier or automated security and identity; improved wireless connections; even cooler photo features; and fluid, intuitive touch experiences.
Get details on what’s new for hardware developers in Windows 8.1 Preview, and access related downloads and guides that will help you develop drivers and devices – from sleek phones, tablets, and notebooks to high-performance workstations or all-in-ones – that will give your customers a seamless experience whether at home, work, school, or play. Find everything you need in the Windows Dev Center - Hardware site.
Submissions for Windows 8.1 and Windows Server 2012 R2 begin now!
As soon as you download the new Windows HCK for Windows 8.1, you can start testing and preparing for certification submissions. The Dashboard is ready for your Windows 8.1 and Windows Server 2012 R2 certification submissions.
The new Windows HCK for Windows 8.1 supports certifications for these operating systems:
Digital signatures available for legacy operating systems in the new Windows HCK for Windows 8.1
When you successfully complete testing for a client certification of Windows 7, Windows 8, or Windows 8.1, use the Dashboard to create a submission package for uploading - the same process that you’ve used in the past. And, if you’re using a uniform driver that’s properly decorated to include Windows Vista and Windows XP, the dashboard has check boxes for free digital signatures.
If your Windows XP or Windows Vista driver isn’t the same binary as used with the newer operating systems, test it by using Windows HCK 2.0. If you test for certification on Windows Server 2008 R2, Windows Server 2012, or Windows Server 2012 R2, the Dashboard won’t have check boxes for free digital signatures for Windows Server 2008 and Windows Server 2003. You can get digital signatures for Windows Server 2008 and Windows Server 2003 by full testing your driver with the WLK 1.6 test kit.
Fast-track Windows 8.1 certification
You can fast-track Windows 8 certified devices listed in the table below for Windows 8.1 certification if:
If the device meets these criteria, here's how you can create a submission:
Submissions are reviewed for these items:
If the review is successful, there's no cost for the submission.
|8 GB SSHD||16+ GB SSHD|
|Erratum ID||1649, 1648||1647|
|NVM cache size (GB)||>= 6 and < 12||>= 12|
|Seq. read (QD: 1)||90 MBps||90 MBps|
|Seq. write (QD: 1)||15 MBps||40 MBps|
|Random read (QD: 1)||8 MBps||8 MBps|
|Random read (QD: 8)||N/A||N/A|
|Random write (QD: 1)||3 MBps||3 MBps|
|Random write (QD: 8)||N/A||N/A|
Random IO performance requirements with a queue depth of 8 won't be enforced under this erratum.
The errata with IDs 1647, 1648, and 1649 will take effect on June 17, 2013, and be valid until Jan 1, 2015. After Jan 1, 2015, performance and capacity requirements – as published – have to be met for certification.
To certify a hybrid with less than 12 GB of NAND, apply errata 1649 and 1648.
To certify a hybrid with 12 or more GB of NAND, apply erratum 1647.
