Like abbodi said: Cumulative Update for Windows Server 2016 for x64-based Systems (KB3176495) gets you same file: AMD64-all-windows10.0-kb3176495-x64_a344b21f039bfc4c4c145af471da86005fa4288f.msu
one of my desktop comps at work crash after installing the latest base system KB3176495 more s**t from MS!!!!!
Interesting... my WSUS found the 3176495 CU and I approved it, download complete and ready. Windows clients 1607 find and install it. Windows server 1607 says "up to date" even if I check Microsoft. I ended up having to pull a copy of the msu and install it manually on the server.
That is the one from august 2nd, today the new CU is released and it supersedes the older one, check the OP in GREEN or the Hotfix Repository.
I got it here on the fast ring and WUMT showed me the x64 download URL Installing x86 Pro 14393.5 and logging in Insider program atm.
