When we reported two weeks ago that Russian leaker WZOR had leaked the RTM versions of Windows 8.1 x86 and x64 online, he claimed that they were the untouched RTM releases; today, we can confirm that this was in fact true.
Shortly after, Windows Server 2012 R2, Essentials, Enterprise, Hyper-V Server and Foundation Storage, as well as the Russian versions and language packs were leaked online too; although not all are confirmed yet, it's likely that these too were the genuine RTM versions.
The news comes courtesy of MDL who compared the hashes to the leaked versions:

Yesterday, WZOR leaked Windows 8.1 RT online as well, which has not been released early. It's probably safe to say that this 2.43 GB image - which includes the updated Office 2013 RT with Outlook - is also genuine.
For those without access to MSDN or TechNet, Windows 8.1 in all flavors will be made available as an update via the Windows Store from October 17th in the U.S., and a day later for everyone else as a free download.
