KUC is no longer useful for post-Update 1 Windows 8.1 x64 updating. WHD is now closed and the final version is being developed. Is there another good updater then? I want to have ALL the updates and I want that updater to verify which updates I already have and download only the new ones, the ones not available through regular Windows Update. Is there such an app? I get all Windows updates, but I just learned that there is NET Framework 4.5.2 out there that wasn't a part of available regular Windows Update. I want an app that downloads even such updates as long as my system actually supports them.
