It appears we may see a bunch of Windows 8.1 RTM leaks incoming, as a reliable source is claiming that they are preparing to upload the full, original ISO's of Windows 8.1. More so, we could also see Windows Server 2012 R2 RTM, Language Packs and maybe even the Windows RT 8.1 RTM.
WZOR, who has been behind multiple Microsoft software leaks in the past, is today claiming that he is planning to upload full, original ISO's for the Windows 8.1 RTM. He has released a list of all the operating systems he's preparing to leak, which includes Windows Server 2012 R2, Language Packs and Windows RT 8.1.
It's currently unclear how or when he will be leaking such files, but he seems fairly confident that they 'will' be uploaded. As said above, he has leaked many Windows OS's in the past, including the Windows 7 RTM and Windows 8 RTM.
Until these files actually leak, we suggest you take this with a grain of salt.
We've already seen the leaks of Windows 8.1 in repacked, modified ISO's, which is generally more messy than its worth. So it will be nice to use some untouched ISO's in the future. Of course, with all leaks, we advice you do not download them for obvious reasons.
