I am able to download updates from WSUS, but not from Internet Windows Update. But when I install KB2919355 again, the same issue comes back. Uninstalling KB2919355 will let me get windows updates from Internet. I am still having the same issue as described above. I found that by removing 'SOFTWARE\Policies\Microsoft\Cryptography\Configuration\SSL\00010002\EccCurves' (configured by GroupPolicy 'Administrative Templates\Network\SSL Configuration Settings\ECC Curve Order' and mandated by DoD STIG V-74413 in Windows Client 10-2.1) I could get Windows Update to work.

When using Edge to open the URL at, I get a certificate transparency error. However the answer at in my case was not helpful. You may or may not still get 10 for free, but you first have to see if 10 is compatible with your device. You don't use Windows Update to upgrade from 8.1 to 10. I'd greatly appreciate any advice on how to fix this one. Using a newly deployed Windows 10 LTSC (1809) with DoD STIGs applied, Windows Update is failing. I'm trying to upgrade from 8.1 to 10, but I keep getting windows update error codes.
