Windows 10 Update error 0x8024402f

Error message: There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x8024402f)

  1. It is a fresh install (the very first operation after first login was a Update and it failed)

  2. Microsoft Tech Support had remote access to my machine and tried everything (including Windows Update Troubleshooting and other tools). They reinstalled Windows and the problem persisted (then, I erased the HD with diskpart --> clean and reinstalled Windows from scratch, using a new MSDN ISO download)

  3. I've manually installed the january 2017 cumulative patch (KB3213986) and installed (actual version: 1607 (OS Build 14393.693))

  4. Tried every alternative (as delete the SoftwareDistribution folder, running some .bat with re-registration of some DLLs with regsvr32, winsocks reset, etc.)

  5. There are no virus (already tested with Clam Anti Virus Portable, just to be sure)

  6. No firewalls whatsoever (my machine is set to DMZ on internet router). Everything works just fine, except Windows Update.

  7. Time and date are correct, using Microsoft's NTP server

  8. I'm using Google DNS servers (8.8.8.8 e 8.8.4.4), with or without them, same error

  9. I was a Windows Insider, but not anymore

I don't know what else I can do (except to wait for a Visual Studio for Linux and throw Windows in the trash) =\

Can anyone help me? =(

UPDATE: I've plugged in an old Wireless USB Adapter and, using Tethering on an Android with my 4G data, the update works normally.

So, the real question is: what is wrong with my normal internet connection that is preventing me from updating? What can I complain about with my ISP?

windows
windows-10
windows-update

Error 0x8024402F means WU_E_PT_ECP_SUCCEEDED_WITH_ERRORS:

// MessageId: WU_E_PT_ECP_SUCCEEDED_WITH_ERRORS
//
// MessageText:
//
// External cab file processing completed with some errors.
// #define WU_E_PT_ECP_SUCCEEDED_WITH_ERRORS _HRESULT_TYPEDEF_(0x8024402FL)

Stop the Windows Update service, delete the content of the folder C:\Windows\SoftwareDistribution\Download. Also exclude this folder from your Anti Virus suite.

Now try again to update Windows 10.

Your ISP (or someone upstream) surely is caching MS updates (in order to avoid downloading million times the same file) and some of them got corrupted...

I don't know what the exact cause is, but the following is a possible workaround: click on Advanced Options under Windows Update and deselect "Give me updates for other Microsoft products when I update Windows."

If it appears your ISP is caching updates and possibly causing this problem, one solution would be to use a VPN connection to download the updates.

While I cannot suggest a VPN option, careful Google research should indicate trustworthy ones to use which would offer a free trial period or allow you to pay for only one month of service which should be less than $10 USD.

Using a VPN would bypass your ISP and their caching entirely, allowing you to get a good copy of the update files.

If the issue persists even after using a VPN, then it would not be the fault of the ISP.

I understand in the original question that the OP's computer is in a DMZ and that the firewall should not be the issue. However, my source of this chronic problem was a Cisco SMB router's firewall setting for blocking/filtering ActiveX controls. Simply disabling that feature resolved the issue.
