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.
