I just had a similar issue, and wanted to describe it for others' reference. All Windows 8 era machines (8, 8.1, WS2012, WS2012 R2) would not update and gave the error code 0x8024402F. This began seemingly sporadically in November of 2018, and audit logs did not show any system configuration changes around that time. The ultimate cause appeared to be AMP blocking Windows from downloading legitimate .cab files from Microsoft websites. In the Security Center event logs, no events were posted indicating that any blocking had occurred. After searching for other issues with our client machines or content filters, we were able to solve the problem very simply by merely d isabling AMP and re-enabling it shortly thereafter. The updates started flowing again just fine after resetting AMP in this way, and we have not had any issues with downloading legitimate .cab or .diagcab files since. I'm not sure if there was some hang in the process that is supposed to be scanning .cab files or with the malware definitions in AMP, but toggling the enable configuration fixed the problem.
