Struggling to get ES 8.6.2 to work (on W10)

Hah. Got it.

I'll put this here in case it's useful for a future user.

Once again (as in the referenced question) I had to set a session-based environment variable:
>set ES_PATH_CONF=D:/apps/ElasticSearch/elasticsearch-8.6.2/config

Then:

D:\apps\ElasticSearch\elasticsearch-8.6.2\bin>elasticsearch-reset-password -u elastic interactive
This tool will reset the password of the [elastic] user to an autogenerated value.
The password will be printed in the console.
Please confirm that you would like to continue [y/N]y

Password for the [elastic] user successfully reset.
New value: YwP0X1n0Ym5KwOpXfojG

D:\apps\ElasticSearch\elasticsearch-8.6.2\bin>

... then got to the "you know, for search" at https://localhost:9500. Hurrah.
