Win 10 x64 1703 Build 15063.413 - Screen Image pre Login there too long before login box.

I am not sure whether this started with the 1703 update but it seem like it did around that time anyway.

When I cold boot I get to the image with the large date etc.

When I click I used to get the login box but now no matter how much I click the mouse, or the keyboard, once the date goes up and out, I am stuck with the image.

It takes sometimes 5-10 mins before I finally get the login box.

How can I fix this please?
