After updating to Windows 10 v1903, [Event ID 200] is recorded in the event log.

The message is as follows.

Could not establish a connection to the Windows Update service.

I suspect that this log may have been recorded due to the Wi-Fi connection being cut off when Windows 10 wakes from sleep.

It's a warning level, so it's best to ignore it, but you have the following options:

[Choice]

ignore
Prevent from being recorded in the event log
Modify the data of DeviceMetadataServiceURL

Well, the main subject.

This article describes options B and C.

Option C is

It is effective for Windows 10 where [Event ID 200,201,202] is recorded.

And it was written online ...?

Repair procedure

Registry operations are at your own risk

Before working with Registry Editor
Make a backup copy of your registry in case something goes wrong.

To start Registry Editor:

Start the execution by specifying the file name ( Field (Win) + R )

Option B

This is a procedure to prevent recording in the event log.

Start Registry Editor
Move to the next layer
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WMI\Autologger\EventLog-System\{fcbb06bb-6a2a-46e3-abaa-246cb4e508b2}
Change to Enabled = 0 (default value: 1)
Restart Windows
End of procedure

Option C

This is the procedure to modify the data of DeviceMetadataServiceURL.

Start Registry Editor
Move to the next level
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Device Metadata
Modify DeviceMetadataServiceURL data to http://dmd.metaservices.microsoft.com/dms/metadata.svc
Restart Windows
End of procedure

Before: http://go.microsoft.com/fwlink/?LinkID=252669&clcid=0x409

Afterword

According to me,

The URL registered in [DeviceMetadataServiceURL] returns "HTTP ERROR 400" when accessed, but the problem has been pointed out since around 2016.

That means

As of July 2019, Microsoft has registered an invalid URL in the registry database.

...? ? ...

According to the writing of Windows 10 Forums, the procedure to fix DeviceMetadataServiceURL is effective for the PC with EVENT-ID 200, 201, 202.

If you want to refresh the event log, why not try repairing it?

Revalidated the URL related to DeviceMetadataServiceURL.

When you access the modification URL (option B) described in this article, 400 ERROR is returned, but if the event log recording stops after the modification, it means that the function is working.

If it doesn't improve, return it to the default value.
