As of 7:49 a.m. EST Media Creation Tool does NOT download the Spring Creators Update. Someone said to wait until after 10 a.m. PST.
The rs4 techbench links are offline, all Techbench options offer the same links to download the iso's, so the HTML (Techbench Minidump by @mkuba50), the Techbench Unlocked site by adguard and ISO downloader by Jan krohn, don't download the iso's yet.
The ESD files from the Products.cab is just as much the official release. The UUP files for Insiders is also just as much the official release.
ESD to ISO is easy just need 4 commands (just time 10-15 min) and then burn files form folder to file iso empty from old version ex. RS3
Are you sure? And the zero day patch? (or i dont know whats the right name). Its not integrated in to the official ISO, or in the released version ESD?
