Hi, Sorry for the slow reply. I was getting things ready for you but then something else popped up...

- It seems the Dell subscription isn't tailored to my laptop at all; I was hoping I could replace using the Dell apps (reading an email is easier than remembering to check regularly).
- System Restore shows OS (C:) (System) ... Image ... DELLSUPPORT as available drives. Disk Management doesn't really indicate which is which...
- Funny thing... I noticed some blocked Protected Memory Access today (from SOSInstallerTool.exe trying to access \Device\Harddisk0\DR0 - not much info around on this but apparently the Alienware SA OS Recovery plugin)
I found that SupportAssist's recovery tools have turned themselves back on!
My previous restore points have all been wiped, and it's creating new ones.
So I'll do that VSSAdmin thing again if you don't mind having another look!
(Apparently an update came through from the MS Store earlier - I might have to just get rid of the app entirely if it's going to keep doing this)

Hell of a lot of shadow copies, for just 2 restore points again
(and some of these shadow copies correspond to restore points I used to have...)
- VSS errors are indeed 8194. They happen with some regularity...

- Here are the Offline scan results / locations
At time of this scan, I was still living in 23rd April
(Time and date on the left is correct - File Explorer was in the future by 9 hours)
Though the time shown at conclusion in the log is correct (04-23-2021 20:49:01), the log file actually shows a future time before that
> 2021-04-24T04:49:01 in the lines above in the log (off from File Explorer by an hour)
As for Microsoft Store, I haven't really explored this yet. I'm aware we can turn auto-updates on/off, but the Store stopped working for me entirely after the first week or two (I could browse, but it always froze & crashed when loading My Library / downloads).
I assumed this was because I haven't yet set up a Microsoft account on this laptop (was actually going to do that right after finishing setting up everything we've been talking about here!).
So I thought the Store would not be available to me - and Microsoft forum threads indicated you did need a Microsoft account to use it - but it looks like it's suddenly started working again anyway!
