Well, you can still catch the link via WUMT, just click on the "Installed" tab (from "Windows Update" tab) as step 1. like it is on the picture, then 2. select update, then 3. copy links.
Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3170411) download.windowsupdate.com/d/msdownload/update/software/crup/2016/06/windows10.0-kb3170411-x64_f10629b678a9ce71bdc05f84e90660d19fdde587.cab
Interesting. Thanks. I asked because of AeroGlass. The x64 W10TH2 has 10.0.10586.456 uDWM.dll, which is much different from x64's .122...
I updated KB3170411 (cab) x32 and x64 by using Dism. x64: dism/online /add-package /packagepath:C:\Windows\SoftwareDistribution\Download\windows10.0-kb3170411-x64_f10629b678a9ce71bdc05f84e90660d19fdde587.cab x32: dism/online /add-package /packagepath:C:\Windows\SoftwareDistribution\Download\windows10.0-kb3170411-x86_6dde58e71a55895022600f2896755d9b5511a97d.cab and now I got 10586.456. Done.
