    Microsoft has relinquished its previous statements that it would not provide Windows 8.1 RTM to developers on MSDN or Technet and has since published the following versions on both services. The final RTM version, a major update which includes numerous bug fixes and improvements to genuine license holders of Windows 8, has also been leaked online by a group named WZOR since last month, according to major IT news sources:

    Windows 8.1 is now available from Microsoft at http://windows.microsoft.com/en-gb/windows/buy?ocid=GA8_O_WOL_Hero_ShopHP_FPP_Null

    Further information for developers and IT professionals about Windows 8.1 RTM:

    Note: SHA1 is critical for determining unaltered authenticity of these files and are directly from Microsoft Corporation. Use a utility like HashMyFiles to confirm the SHA1 checksum on these .ISO files. If you are having difficulty extracting the .ISO files for an upgrade path, you can boot from disc. If you can not create a boot disc, ImgBurn is a freeware, lightweight utility that allows you to burn ISO files to DVD. You may also run setup.exe for upgrade after creating the DVD media.

    Microsoft has confirmed the RTM build number is Windows 8.1 9600.16384.130821-1623 and we now have the highest level of certainty that these files are the Windows 8.1 "Release to Manufacturer" (RTM). These files were released to OEM parners by September 1, 2013.

    Although the files have already leaked, we now have dates for the official release timetable:

    RTM Leaked by "WZOR" Group: August 23, 2013
    Released to OEM Partners: September 1, 2013
    TechNet/MSDN/Volume Licenses: September 9, 2013
    Official Public Availability: October 17, 2013

    The 32-bit and 64-bit versions are compatible with English (US) and English (UK) languages. Here is the following information:

    We recommend that you:
    • Download any files at your own risk. We are not responsible for lost data or damage.
    • Observe best practices, including backing up your data prior to the installation of any operating system updates or modifications.
    • We, again, strongly recommend that you thoroughly backup your system prior to the installation of any operating system update.

    The files have been tested on various types of hardware, without problem or difficulty. This does not guarantee that the Windows 8.1 RTM will work for you. You will want to clean install the software, by burning the ISO file to disc, or you can extract the .ISO file using WinRAR, and run the upgrade path.

    If running the upgrade path after extracting the .ISO file, temporarily disable your anti-virus, save all of your work, and turn off all programs before running the installer. This will improve the likelihood of a proper installation. Follow all on-screen instructions.

    Support Files for Genuine Microsoft Windows 8 License Holders

    Windows 8.1 is a service pack-type upgrade. These files are considered support files and can only be used with a legitimate, genuine Windows license key. If we are asked to remove these files, at any time, by Microsoft Corporation, we will do so, without hesitation. However, these files remain online with the proper SHA1 data authentication through torrents and other means, by other individuals, with whom we have no association. In any event of where you may download these files online, you should be attempting to download these files for emergency support reasons or system failure and should verify their authenticity using the SHA1 authentication. Until the release to general public, this should be among the few, if only circumstances, that we could justify for the download of these files.

    Important Windows 8.1 Release Notes

    Typically, the release to manufacturer version of Windows is the final build (compilation) that is sent to large corporate clients before it is released to the retail marketplace in areas like Windows Update, the Windows Store, and made available as an official slipstream retail bundle in stores.

    Typically, in the past, with the release of service packs, that solve many security vulnerabilities and issues as a compilation of Windows Updates, the RTM is sent to partner companies so that they can essentially brand the new version and prepare it as a bundled release on OEM systems. This means that the package is sent to large computer manufacturers so that they can add their own branded software, and, potentially, device drivers, to provide an optimal experience to the purchasers of new computers.

    With the release to manufacturer version of Windows 8.1, it was initially unclear as to whether or not these would be the final "bits", or the final compiled version of Windows 8.1, due to much online conjecture. However, the release of Windows 8.1 will likely be followed by a large number of updates to the Modern UI applications, and it has now become common knowledge that these are the final bits for the software.

    This makes the final version of Windows 8.1 9600.16384.130821-1623, for anyone paying attention.

    The release of Windows 8.1 on MSDN and Technet follows disdain from developers and others who have paid a hefty price to gain early access to Microsoft software. Plans were initially to keep the RTM off the table to these individuals and organizations, prompting some to believe that the final retail release would be a different kernel build from the RTM - a seemingly odd set of circumstances, unfamiliar to most developers. As of the 9th of September, Microsoft did a 180 degree u-turn over this issue, responding to customer feedback and stating:

    Traditionally, the RTM gives developers and corporations time to adapt their software to the updated operating system's application programming interface and code changes. It should be noted that while Windows 8.1 is essentially a service pack that cleans up a lot of interface issues in Windows 8, the kernel of the operating system has been significantly updated, and there are significant feature improvements that may not have normally been found in a traditional service pack. It may also be a way of indicating to potential customers and adopters that often cited issues with the Windows 8 interface have been resolved under the "8.1" moniker.

    According to NeoWin:

    It is likely a large number of updates will be pushed out from the Windows Store and Windows Update for Modern UI apps and operating system updates, primarily because the RTM version is designated for corporations to prime the operating system for a release to their customers. Irregardless, everyone will likely have to download a large number of updates after Windows 8.1 goes "retail" in mid-October.

    With that in mind, this is the gold version of Windows 8.1, and future patches from Microsoft are suspected to be forthcoming after general availability to the public; without any additional build releases coming out. However, Microsoft still emphasizes that the RTM, this time, is still being tested. Large corporate clients such as Dell, Lenovo, HP, and many other partners, with access to the RTM, will report back difficulties that will be patched on the day of the retail release. It has widely been suspected that most semiconductor companies like Intel and AMD already have access to most of the development builds.

    If you are currently satisfied with your Windows 8 experience, you should not seek out Windows 8.1. However, the Windows 8.1 Preview version is now essentially "out of date". Loyal Microsoft customers may be interested in picking up a Technet or MSDN subscription from Microsoft if they are interested in early access to Windows 8.1 Release to Manufacturer ("RTM").

    Any genuine customer who happens to obtain the software should be sure to follow the important release notes listed from Microsoft at the top of this post and confirm authenticity using the SHA1 checksums at all costs. Many IT news sites are reporting that the last leaked version of the RTM build (8.1 9600.16384.130821-1623) was actually the final version.

    Needless to say, those with access to this software should know what they are doing, and always make sure they back up their files. They should be certain to take all necessary precautions before deploying the software in any production environment.

    It is confirmed that Windows 8.1 has been made available to academic institutions and students via Microsoft Dreamspark Premium. It is also confirmed that "RTM is RTM" and no further bit changes will be required for general availability. So, essentially, if you install Windows 8.1 RTM now, you will not be required to install an additional version again in October.

    I have done an Update install using the setup.exe from a flash drive. Used the key from the download to install and the original Windows 8 key to activate.

    Seems to be working fine.

    Yes you are....in order to get a key, you have to have purchased a MSDN or TechNet subscription or have won the MVP award which gives you the those accounts. It's one of the many benifits of winning the coveted MVP award from MS or by purchasing a subcription from either or both.

    As of September 1st of this year, MS has shut down the TechNet subcription....so you can't purchase that one anymore....MSDN is still avaiable but be prepared to open you checkbook or CC....it's expensive.

    We are prohibited from talking about or issuing, even temporary license keys that are not sanctioned from Microsoft, on this website.

    You need a legitimate or temporary Windows 8.1 retail key to access the software, which will be available from Technet/MSDN. There is a method being used by some to use a temporary key and then switch back to the original key using:
    Code:
    slmgr -ipk yourkey
    This is done after unlocking the RTM using a temporary key, which may not be authorized by Microsoft, so we cannot discuss it here. I hope this helps. The original key will validate and authenticate, but because the RTM is not available through Windows Store, Windows 8.1 does appear to be locked down to manufacturers at this time.

    @nmsuk and many others have confirmed this method works.

    To rehash:
    • You would download the RTM.
    • You would enter a temporary key, which we can neither identify or give out, since we don't have one and it may not be permissible.
    • You would then use slmgr -ipk yourkey under an elevated Command Prompt to re-enter your original Windows 8 key, once you get back into the updated OS.
    This is a method being used by people who absolutely need access to the RTM and are already legitimate Windows 8 customers. What is happening here is that those with access to the RTM are being given retail keys that will allow for its activation. By October 18th, the same bits will be downloadable as the redistributable version for IT support personnel on the Microsoft Downloads website. The Windows Update/Store version will likely be a much smaller download for consumers who already have Windows 8 installed. The RTM version that has leaked contains the entire package for a clean install, since vendors will be likely to use Windows 8.1 when setting up new laptops and desktops for retail sale. The point of the RTM release has always been to get it to manufacturers so that when it is published, to regular customers who already own Windows, the latest version of Windows is already on hardware in stores with full device driver support. I hope this helps.

    You can create bootable USB media to install/upgrade/clean install Windows 8.1 as well, using the same method I described with Universal USB Installer.

    Problem solved with my secure boot not being correct. Had to go into the bios and enable it and then enable force default key. Thank you for the help bassfisher and Mike.

    Microsoft updated Windows 8.1 RTM today with Security Update for Internet Explorer Flash Player for Windows 8.1 for x64-based Systems (KB2880289). This update was previously applied to all Windows 8 versions with details found here.

    Please clarify for me. I am a bit confused......
    I have a laptop presently running Win 8 Pro 32-bit. It came in the form of an upgrade disc and a product key.
    I am going to download the Windows 8.1 (multiple editions) (x86) - DVD (English) iso from this thread.
    I'll burn the iso into a bootable DVD.
    That is not a problem.

    Now, my question :
    When I install the 8.1 using the DVD and I am asked to input the product key, do I use my Win 8 Pro key ?

    Or, a win 8.1 product key is needed to install, and then use my win 8 pro key to activate?

    Thank you.

    I apologize.
    I did not read the posts carefully.
    I missed the part about "temporary key".
    Please disregard my question.

    Thank you.
