There will be a time, Windows Update failed in Windows 10 Operating System. You might trying clear somes SoftwareDistribution folders, restart related update services and run some OS fixes never successful.

I discovery this. I hope it might help you updating your Win 10 devices.


1. Windows update fail to get latest update.

2. Error message: "Your device is missing important security and quality fixes."

3. Sometimes, Windows update able to get the list of updates but fail to download.

Miracast or wireless display or wireless projection might fail when connecting to miracast device or wireless display device such as tv and projector.

When I went through for the tips in resolving the issue, most of them are about creating new firewall rules or disabling Windows Defender Firewall. However, adding new rules for %systemroot%\system32\WUDFHost.exe sometimes not fix the issue because the rules already there by default (local rule).

In some cases, miracast works in projecting from PC to TV but not when PC is joining to domain.

Disabling Windows Defender Firewall would solved the issue but it exposed PC to unwanted inbound and outbound connections.

This is steps to edit configuration.yaml if dashboard is inaccessible due to configuration.yaml error.
