Download Windows 8.1 RTM, Visual Studio 2013 RC and Windows Server 2012 R2 RTM Today

Download Windows 8.1 RTM, Visual Studio 2013 RC and Windows Server 2012 R2 RTM Today

Starting today, we will extend availability of our current Windows 8.1, Windows 8.1 Pro and Windows Server 2012 R2 RTM builds to the developer and IT professional communities via MSDN and TechNet subscriptions. The Windows 8.1 RTM Enterprise edition will be available through MSDN and TechNet for businesses later this month. Additionally, today we’re making available the Visual Studio 2013 Release Candidate which you can download here.

We heard from you that our decision to not initially release Windows 8.1 or Windows Server 2012 R2 RTM bits was a big challenge for our developer partners as they’re readying new Windows 8.1 apps and for IT professionals who are preparing for Windows 8.1 deployments. We’ve listened, we value your partnership, and we are adjusting based on your feedback. As we refine our delivery schedules for a more rapid release cadence, we are working on the best way to support early releases to the various audiences within our ecosystem.

In providing the best developer tools to our customers, Visual Studio 2013 RC enables development teams to build, deliver and manage compelling apps that take advantage of today’s devices and services. With the release of Visual Studio 2013 RC, we’ve made available additional features and functionality to enhance developer and development team productivity and agility. For more information of what’s new in Visual Studio 2013 see today’s blog post from S. Somasegar.

With these updated platform and tools bits, developers will be able to build and test their Windows 8.1 apps. The RTM versions of tools, services, and platform are required for store submissions which will open up for new Windows 8.1 apps beginning at general availability on October 18.

Given the accelerated rate of technological advancement we continue to see in the industry and here at Microsoft, it’s an exciting time to be an app builder. We recognize the critical role developers play—the breadth of our apps ecosystem is a key pillar of the Windows experience. It’s an essential end-to-end relationship – we deliver the tools, services and platform to give developers the flexibility and opportunity to innovate and build experiences for Windows that make all our lives more productive and fun. 

We also recognize that our commercial customers need time to perform application compatibility and other testing and validation to best plan for their Windows 8.1 deployments following general availability on October 18.

The primary purpose of Windows 8.1 RTM and Visual Studio 2013 RC availability is for testing as our engineering teams continue to refine and update the product and tools in preparation for Windows 8.1 general availability on October 18 and the release of Visual Studio 2013 RTW.  Third party apps may require final refinement to onboard into the Windows Store at the October 18 GA milestone.  However, we’re confident this pre-release will enable developers to ready their Windows 8.1 apps for customers while validating their existing apps function as expected on Windows 8.1

Similarly, we continue to validate the Windows Server 2012 R2 software with our partners and expect to make further updates to the build for general availability on October 18 as well. 

We are pleased to provide non-production support for Windows Store app development and testing for Windows 8.1, via forums and assisted support channels.  For links to those resources, along with existing Windows 8 support options, please visit the Dev Center support options page. We will also provide assisted support for Windows 8.1 RTM and Windows Server 2012 R2 RTM through standard commercial support channels.

We are excited about the innovation we are delivering in such a short amount of time, and are pleased to be able to share these pre-releases with the communities.  Thanks for your continued support and feedback, you can reach out to me anytime, either using the comments here or on twitter @StevenGuggs.

  • For Matt B, we came across this and it was caused by the languages not matching i.e. English international is installed and trying to upgrade with an EN-US disk

  • @RetroRecursion -

    The upgrade path depends on the OS you are upgrading from, more details are available here. At GA, Windows 8 users will be able to upgrade all their apps, personal files and settings to Windows 8.1. As communicated at Build, users upgrading from Windows 8.1 RP to Windows 8.1 RTM will have to re-install their apps.

    @Real McCoy

    We will have more to share in the next weeks and months, but in the meantime you can find demos and resources at:

    • Xbox One Official Website -

    • Xbox One Reveal and E3 Microsoft Keynote -

    • Build 2013 keynote -

    @Mike - For actual upgrade, you will have to wait until GA.  This release is for testing 8 and 8.1 apps and drivers.  The ability to upgrade 8 will be available via retail channels at GA

  • What about DreamSpark Premium (students)?

    Could you tell me when 8.1 RTM will be available there?

    I found this one:

    "Available to these Subscription Levels: DreamSpark Premium"

    but there is no more info, and not downloadable yet.

    thank you in advance,


  • @Guggs

    I take it Partners with Action Pack Subscription services aren't included in this, correct?  

    It would be nice for us selling/supporting services to be able to access the RTM versions early so we can be ready to hit the ground-running on Day-One as well.  

  • I agree with Florin about Silverlight.

  • When will the arm/winrt version be avaliable @ dreamspark?

    I can still only find the x86/x64 preview versions.

  • @Guggs - thanks for the clarification.

    It is a shame as I was hoping to test my LOB apps in 8.1 but can't unless I do a re-install of VS 2012, VS 2013, Office, SQL 2012, SQL 2008 etc etc - that would waste a day or more so looks like I will be waiting


  • VS2013 after RTM should work with VS2013 key

  • What about DreamSpark Premium users ?

  • @Stian - The x86/x64 RTM code is all we are providing right now.  The RT update will be available at GA.

    @Sid and a few others - It is available via DreamSpark Premium subscriptions.  Subscription admins can download it today through their MSDN Subscriber portal.

    Also, I confirmed that you can upgrade if you get a retail key from here -  If you aren't seeing the same, let me know and I can continue to investigate.

    Thanks all for the comments and questions.

  • I guess when they saw the Windows 8.1 bits leaking to the web just a few days after it hit the RTM milestone and was sent off to OEMs, they've had no other choice than releasing right away. I can image that this time not just the usual enthusiasts, but also people with a MSDN/TechNet subscription were going for the leaks, and now criminalizing them in any way for using unpublished software would've been even more foolish than their initial decision to hold it back.

  • " It is available via DreamSpark Premium subscriptions.  Subscription admins can download it today through their MSDN Subscriber portal." Does that mean that only admins on dreamspark can access it? Because I have dreamspark premium from my university and I can't access Windows 8.1 there. Only  the regular 8.

  • What about action pack? One thing is developers, but we IT Pros need to learn the new stuff before our customers

  • @Guggs

    ----- Also, I confirmed that you can upgrade if you get a retail key from here - ...

    Thanks for the information - just to be clear - these keys did not solve the upgrade issue for me in that I only get the choice of keeping personal files.

    Also I have just done an upgrade on a surface and I had the same choice there but it seems to have left all my apps intact but removed all my desktop apps.


  • @Niclas and a few others asking about Dreamspark premium - Yes, for now only subscription administrators can download Windows 8.1. It will be released on the webstore of your university (and any university that has DreamSpark Premium and has deployed its own webstore) by 9/19/2013.

    @JT - Checking in on Action Pack - I don't have any details yet, but will report back if I do

    @Mike - Thanks for the feedback and checking that...I've flagged it here and am continuing to monitor

    Thanks all
