What if I told you... they do? Windows 8.1 was RTM in October 2013, in April 2014 an updated installation image was released, and in December they released another updated image. You can use Microsofts media creation tool to always get the latest 8.1 image released. I'm not sure if it includes later versions of .NET (4.5 in case of Windows 8.1), but it still helps a ton.
I saw this in another thread, and thought I would post it as an independent thread for more visibility.
Like probably many on this forum, when the original thread about the MS Windows 8.1 refresh media creator tool link showed up, I downloaded all of the various English-language ISO versions. (Just in case I find someone that needs a re-install, and needed that version of 8/8.1.)
I wasn't personally aware that they refreshed the refresh media ISOs in December 2014, until the quoted post above. So I'm downloading them again. The first one I downloaded, did compare differently to the one that I downloaded before, so I take that as a sign that they were indeed updated.
So have at it, get your refreshed refresh ISOs! 🙂
