The first time I installed the update BIOS with Support Assistant.

Then i disable Bitlocker and download BIOS update from site:
https://support.hp.com/ua-uk/drivers/hp-probook-450-15.6-inch-g10-notebook-pc/2101593792

And update.
The update went through without errors.

That's right, but Windows and HP can send the update. In my case, that's how it is. I don't update with Windows firmware because it can often cause errors and you can say goodbye to your laptop. First, I update with HP, and then when the Windows update arrives, I download and install it because that way it only installs the driver and doesn't do the whole update process.

There are no restarts or anything, it just shows the driver version, but as I said, that has no effect. It's actually a step to follow so that you don't always see that driver in Windows Update. Now, if you update the firmware through Windows Update, there is a high risk that the update will fail. It happened to me, and fortunately I was able to recover the BIOS.

I don't quite understand what you mean.
First time I installed the update BIOS via HP Support Assistant.

Then I updated again by downloading from the HP website.

HP and Microsoft collaborate to offer BIOS updates, but when updating the BIOS with HP, it does not update the Device Manager driver; only the BIOS offered by Windows updates it, but this update may take weeks or months to become available.

For the rest, read my messages because I prefer to update first with HP and then with Microsoft.

At the following link, you can see the updates offered by Windows, but do not use them until they send them to you.

Microsoft Update

Thank you very much for your answers.

But allow me a few more stupid questions)

Update BIOS with Microsoft, you mean Security Updates (monthly) from Microsoft?
Because, I have never seen update BIOS from Microsoft as a separate update.

[resistencia]

It is a separate update, in many cases it installs automatically and you don't even see it. In your case, understand that you have driver version 1.9, and it should be 1.10, but Microsoft has not sent it, so you must wait. In many cases, it can take months.

Previously, Microsoft offered it first, followed by HP, but many complaints about update failures from users who used the Microsoft method forced HP to offer it first, then Microsoft compares it in Device Manager, which is not updated, and sends one that does not go through the whole process of rebooting, etc., but only installs.

I hope everything is clear and resolved.

@Resistencia

Oh, I think I understand what you mean.

This updates (From Windows Update) contain these drivers (BIOS, ethernet, etc)?

I thought it was just an update to the HP software.

@Resistencia

Thank you very much for the explanation.
I will wait for the update from Microsoft.
Very grateful.
