Glad to see that you are least back up and running.
You can either hit the Update now button or create bootable media from
https://www.microsoft.com/en-gb/software-download/windows10This will give you the latest Creators release of 1703 15063.0 and subsequent updates will take that to 15063.138
There are some things you need to be aware of that this update does.
It removes Control Panel from the Start menu but you can go Start - type Control Panel then right click on it and select Pin to taskbar.
It also replaces Command Prompt with Powershell in the Start menu - you can change this back by going Start - Settings/Personalization/Taskbar and use the toggle switch to turn that off.
I also found that it removes some normally hidden items from Network adapters which can be viewed in Device Manager/View/Show hidden devices.
Using the Network reset in Settings/Network and Internet will reinstate those, although you will need to re-enter the wireless password at the taskbar WiFi icon afterwards.
However, in two instances when I've gone to change back to the DNS servers I use for Wireless and Ethernet, I've found there was no Ethernet listed to change.
You can find these by going Start - type ncpa.cpl and press enter.
I'm not sure if this was because of the latest update or because of the Network reset but to reinstate the Ethernet, I needed to run the cmd netcfg -d from a Command Prompt (Admin).
I can then change the DNS servers back to Google's which I normally use and again, had to re-enter the wireless password.
My boot up time is a little bit slower, but not too much that I can't live with.
