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.

  • Please add 3 and 5 and type the answer here:
  • Post
  • Just to clarify if I install the RTM there will be no need to reformat on Oct 19th all updates will be made available via windows update.

  • Thanks for reversing this policy.

    Ironically (for me), I already canceled my MAPS subscription when MS announced we would not get the 8.1 RTM bits. Since it was MAPS, cancelling voided the licenses so I then bought the individual products I needed so I'd be legal.

    Now MS changed the policy. While I applaud the decision to release to MSDN early...this changing your mind just cost me some money though.

  • Does anyone know if or how we can upgrade from the preview to the rtm version just released without losing programs?

  • @Guggs, thanks for the release. Can you please tell me:

    - If XRT in Xbox would be based on Windows 8 or Windows 8.1?

    - If we build an app for Windows store, would it be available in Xbox store?

    - If the TV connected to Xbox One is touchscreen, would I be able to use touch apps with it? Does XRT core support multi-touch?

    Letting WinRT apps running on XRT and later WinPhoRT (next year with Blue update), would bring tons of incentives for your developers. We need one store and one update policy for all platforms! :-)

    Thank you!

  • Great news, thanks!

    However, will any changes that come out between RTM and GA for Windows 8.1 be out as Windows Updates for RTM, or will we need to reinstall/apply 8.1 GA ?

    Thanks

  • Any recommendation to upgrade a Surface Pro from 8.1 Preview to 8.1 RTM?

    Fresh install from USB is a good idea?

  • Even with the 8.1-release, Windows 8 is still the biggest fail since Vista. Windows tablets and Windows phones (for which Modern UI/Metro was in principal designed) have not been selling very well (to say the least). So Microsoft might as well have stick to Windows 7 UI improvements instead.

  • @Johnk.....

    windows 8has more users than all of mac OSX combined....

    go troll somewhere else

  • That's nice. If you reinstate Technet, I'll remove Linux from my desktop and go back to Windows.

  • @Sam Jones.  You do not want the N version.  If this "N" version of Windows 8 is like the N version of Windows 7 N, it means there is stuff messing.  In Windows 7 N, Windows Media Center was missing.  Maybe other stuff like Windows Media Player too was missing.  Yet, Microsoft may allow you to download these missing parts.  The N version maybe used to comply with some European thing about not bundling these components.  I do not work for Microsoft.   I did mistakenly install an "N" version of Windows 7 though.  

  • It appears that the ISOs on MSDN only allow for relatively clean installs. There's no full upgrade option. When starting setup on a Windows 8 RTM machine, the only options I get are:

    - Keep personal files only

    - Nothing

    I wonder why upgrading would be disabled in these ISOs?

  • Existe una version free?

  • @RetroRecursi​on

    You can try to force it to upgrade by deleting cversion.ini (which is the file telling the ISO that in-place upgrades are not allowed). This was a trick that some people used back in the day for 8RP->8RTM. Might work for 8RTM->8.1RTM. A tool for removing cversion.ini from the ISO can be found at code.kliu.org/.../winisoutils

  • @Sam Jones, yes @D Morgan is correct.  Thanks for explaining.

    @Aaron - actually, GA is the 18th, and you are correct, that you will not have to reinstall.

    @Eric - yes, fresh install from USB should work great on your Surface Pro

  • I suppose fresh install means loosing program/setting/data.

    How can I upgrade a Windows 8 RTM machine to 8.1 without losing program/data?
