Weird behavior at restart, please help analyze error reports.

Assuming this may be a repeat of what you initially posted- an update failing- please post a screenshot of your Disk Management:
Windows key + X, click Disk Management

Thanks.

Correct me if I'm wrong, but it sounds like your computer is attempting to upgrade to 1607 but is rolling back at some point during the upgrade. If this is the case, please watch it while it attempts an upgrade and write down the result and extend codes.

I don't think that that is happening. Where did you get the impression that it was rolling back?

We will also want to see the upgrade logs, Microsoft has created a great document on troubleshooting Windows 10 upgrade errors that specifies where the log files are located. Please post them here, along with where they were located.

I might have to look into that more later. Right now, the instructions in that document are confusing me (and I don't want to risk messing up the current update process by attempting to do what's in them). Is there some dedicated directory that I can search for the logs?

That looks clean - legacy BIOS, plenty of room on C:

One thing to check- make sure you have, say, at least 700Mb of unallocated space on your system drive. (It looks as if you may have already).

How would I find out?

Easy way - a decent partition manager. (See bottom right)

You may be able to find out using Disk Management by attempting to extend a partition (but not actually doing it). I'm not so familiar with that.

Then there are command line options.

I can't do that right now. I'd have to install a program, and I don't want to risk it with the update downloading.

I checked, and Disk Management doesn't show an option to extend the partitions. Just an option to shrink them.

Put it this way. If Windows requires to create a larger recovery partition, and there's no room to do it, the upgrade will fail.

E.g.
Free Partition Manager Software - AOMEI Partition Assistant Standard

Downloading and installing a program whilst a download is in progress is perfectly ok.

What would you recommend as my immediate course of action, then?

By the way, I don't know if this information is accurate, but I found this by right-clicking the system drive in Disk Management:

I have AOMEI downloading. What exactly should I do after installing it (both in order to find out whether I need to expand the unallocated space, and to do so if I indeed do need to)?

Use it to inspect your partitions, check for unallocated space and as necessary shrink a partition on your system disk to leave say 700Mb unallocated. It's well supported with help.

NB you probably can't shrink C: on line.

I can't see how to check for unallocated space in AOMEI.

I believe that Disk Management has the ability to shrink partitions. Would it be better to use it or AOMEI?

NB you probably can't shrink C: on line.

What do you mean?

EDIT: What are the chances of the 500 MB not being enough? One thing that I forgot to mention is that the previous computer that I had also upgraded to the Anniversary Update, and it had the same partition sizes as far as I can recall.
