In reply to Rose B.

Hi Rose;

I just ran the two lines in PowerShell again:

wuauclt /detectnow

Get-WindowsUpdateLog -LogPath C:\windowsupdate.log

and found that the log did show the date and time:

…
2020-09-17 17:25:27.5260937 77112 87432 Agent Initializing global settings cache
2020-09-17 17:25:27.5260947 77112 87432 Agent WSUS server: http://cal-mss2:8530
2020-09-17 17:25:27.5260957 77112 87432 Agent WSUS status server: http://cal-mss2:8530
2020-09-17 17:25:27.5260965 77112 87432 Agent Alternate Download Server: (null)
…

Can you post a sample of what your log looked like?

This worked for me in build 1909, however, I don’t see a date/time stamp in the log file. Did this change or am I missing something?

In reply to Joe. Sorry Joe, I did not find anymore useful information on the source of Windows Updates.

Hello,

At the end there you said you would post the answer when you find it.

Did you ever find it? Or is it posted somewhere else?

Thanks,

Joe

In cmd.exe (or even in powershell.exe) type:
findstr “WSUS server:” c:\windows\WindowsUpdate.log

This will give you output similar to:
2016-11-09 09:39:45:820 872 a8c AU # WSUS server: http://wsus-XX:8530
2016-11-11 04:02:41:404 852 53c Agent * WSUS server: http://wsus-XX:8530

That’s your WSUS server.
Cheers,

In reply to Ian Matthews. Hi Ian, Thanks for your reply. No sign of anything to do with the WSUS server in the log files, even though I now know that it is at last going to the WSUS server for updates.

In reply to Jon. Hi Jon; I have run that command on 1511 and 1607 and both produced the results shown in post. Have you searched for the name of your WSUS server in the logs?

Hi, Thanks for posting this – couldn’t find the info anywhere else. Unfortunately when I generate the log files they have no info in them about the source of the updates (no ‘Agent’ tags, URL etc) . I have 1607. Am I missing something? Thanks, Jon

[…] Worse, the Windows Update log shows it cannot talk to the WSUS server: If you want to read your Windows 10 Windows Update Log, we have the process detailed HERE. […]
