KB3062095 has been released for all 3 (x86, x64, server), KB3062260 and KB3062282 are for server only. All of them available at catalog.update.microsoft.com I've found going there, searching for "preview" and sorting by newest provides good results.

why cant i install any of the 10074 updates even though i have build 10074 installed i already have some updates installed they are: KB3038314, KB3061161, KB3061162, KB3061163, and KB3061185
NET Framework 3.5 components have been updated. Also, new AMD Catalyst driver (build 1023). File versions are the same, but they are newer builds and not bit identical.
I received two hofixes KB3051768 and KB3046002(which required to the system to be restarted after installation).
