Apart the user of twitter of which we do not know the reliability (but most likely is the usual fake informer) . The most obvious answer I can give is no, because Slow and Fast Ring Ring does not share the same static links (and it was also discussed in other threads).
Any ESD link for enterprise of 10138 x64 (similar pro, i know not active this links now, but i want add too my download manager to download as link activated)
Only temporary individual links for fast ring now. Will be post here but when new build will be enable! No need grab it now!
Updates are downloaded to C:\Windows\SoftwareDistribution\Downloads. There will be a folder in there with a long string of letters and numbers. When you watch the new build download in the Windows Update box, it will finish and prepare to install. You can then see an ESD file in that folder with all the numbers and letters. Copy this file to another place, then you have it to de-encrypt! I keep that folder cleaned out so there aren't an unmanageable amount of folders in there.
You'd better believe, Killer Lizard has friends more "insider" than we are EDIT: Nothing updates more than "Definition Update for Windows Defender"!
