It sounds good that 5 updates have installed. Fingers crossed that v.1709 will come in well. Good luck.
Here's what I was working on before the recent developments...
(1) I mainly complain of the Windows Temp folder(s), such as C:\Windows\Temp. I think each Windows installation best have its own. Also, even in a single installation, Windows or a 3rd-party app may not honor the move.
(2) I'd still like to see the DiskPart listing itself. But what matters is...
(a) Does an HDD/SSD have to be Disk 0 for (some) Windows updates/upgrades to work?
(b) What are the consequences of installing Windows onto a partition on Disk 0, then switching things around so that it becomes Disk 1?
Edit: At an administrator Command Prompt or PowerShell, let's see...
BCDEdit /Enum All
Click the icon in the Shell's header, & use the Edit menu to copy/paste the result here.
