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.

  • Disappointed!!!!

    Just downloaded the Windows 8.1 RTM and installed it (several times) on a new Lenovo U430 (new machine with Haswell processor) and nothing really work. Visual Studio 2012 and many other programs (win32 apps) simply fail to run giving a "{app name} has stopped working" error. Even the Intel driver software does not run and gives the same error. If this is better compatibility, then something is terribly wrong. I had to revert back to Windows 8 just to continue to use Visual Studio 2012. I have search the internet and found I am not the only one having this issue and this issue was even found in the Preview version. On my new computer, Windows 8.1 RTM is UNUSABLE. The base OS seems to work and all the Windows 8 apps (I do not use these) work fine, but many of the desktop apps (even Microsoft apps) no longer work. Please fix this.

  • I have a MSDN account and downloaded the 8.1 RTM and it asks for a new key. I downloaded a key from MSDN and it allows me to upgrade my Win 8 machine, keep settings, files, Apps. However I hesitate using  the MSDN key. Anyway around this and I can keep my current retail 8 key?

  • When will 8.1 Enterprise keys be available from MSDN?  If you have to upgrade within the same edition, then, that's the reason why it's not working for me -- the keys on MSDN are 'regular' Windows 8.1, and 8.1 Retail.  Where are the keys for things like 'Pro', and 'Enterprise' ?

  • Sorry, just checked again on MSDN there is Windows 8.1 Pro, and Windows 8.1 keys.  No 8.1 Enterprise.

  • I did a clean installation of Windows 8.1 Pro N. After installation I tried downloading Skype from the Windows store. I got an error and tried other Apps. I can't download any App from Windows Store. I get an error "Something happened and this App cannot be installed. Please try again. Error code 0x8020002e

  • I've wanted to install the RTM version from MSDN AA but there is no such thing there. I can install only Microsoft Windows 8.1 Professional Preview from DreamSpark Premium. Can you help me? Thank you!

  • Please give us info on installing 8.1 pro.  We had it but, we had to send the main comp. for repair.  Now, it  is blank& Micro. is causing us delays.

  • Still this version is not available for my dreamspark account. hopping to get soon :(

  • Hello,

    I tried to install the Windows 8.1 upgrade on my Dell Latitude E6430, which is currently running Windows 8 RTM in a native VHD boot scenario. Unfortunately, I got an error message saying "You can't install Windows on a virtual drive." I would like to perform the upgrade directly, rather than starting with a fresh installation of Windows. Was this scenario tested at Microsoft?

  • From the comments I've read here, apparently you have to have a different product key for Windows 8.1 if you perform an upgrade using the full Windows 8.1 media (ISO or USB Flash Drive). Is that accurate? Why would you need to have a different product key for setup from ISO/UFD, if you can perform the upgrade through the Windows Store, with the same product key you used to install Windows 8 RTM? That makes no sense to me.

    So, in the native VHD boot scenario, should I consider myself SOL for upgrading until the Windows Store General Availability (GA) update comes out on October 17th, 2013?

  • where can i download windows 8.1 without preview?

  • Upgrade went well from 8 Pro retail to 8.1 Pro RTM. There seems to be an issue with hibernate however, my PC just shuts down. I disabled it and is has been fine so far. I also see issues with USB Root Hub drivers...

  • Re-installing USB 3.0 drivers took care of the USB Root Hub issue.

  • I've seen a number of posts about the DreamSpark Premium members not seeing, so I've been digging in.  Here's a couple things...

    If you are an admin for DreamSpark Premium, here is what you should see in MSDN -

    If you are not an admin, but a member, your admin will have to deploy it, which takes a few days.  But want to clarify that the ELMS webstore is not the same as the MSDN portal where you enable it.  Seems there was some confusion, so I wanted to clarify.

    Everyone else...definitely seeing your questions and comments and am digging up answers with the product team before posting here...stay tuned!  Thanks!

  • @BenIsbell and a few others using VS - this page has a ton of information on upgrading, what works where and more -
