Windows 10: Windows Update error 0x8024401c and 0x800705b4

[Guest thenewmessiah]

Hi All,

I'm having problems with Windows Update on many Windows 10 clients (build 1511 and 1607).

All clients are connected on an internal WSUS server on Windows Server 2012 R2.

 

Many clients works fine and regularly gets updates from WSUS, but on an half of them, I get this error if I check for updates:

"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: (0x8024401c)"

or

"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: (0x800705b4)"

 

I have followed all suggested steps available at this URL:

https://support.microsoft.com/en-us/help/10164/fix-windows-update-errors

 

1) I have executed the "Windows Update troubleshooter"

2) I have manually installed the most recent update KB

3) I have executed "DISM.exe /Online /Cleanup-image /Restorehealth" and "sfc /scannow"

4) I have manually upgraded the build from 1511 to 1607

 

Nothing changed.

 

So, I have tried changing my GPO to point to Microsoft servers instead of my WSUS, and if I do this, the Windows Update client getting errors, starts to work.

 

On some clients, If I run the PowerShell command "Get-WindowsUpdateLog", I can see this log:

I have also tried to stop the AntiVirus, but nothing changed.

 

Do you have any suggestion?

 

Thanks!
