I have noticed that it is possible to see Windows Phone as one of the sites where one can run SEDE queries. As an example, here is a query listing the recent posts.
This query shows the date as the most recent post from as September 2022. This announcement was posted in November 2022: The Windows Phone SE site has been archived The URL https://windowsphone.stackexchange.com/ redirects to Area51 page where you can read that the site "was closed 11 months ago."1
It seems that in the past closed sites used to be removed from SEDE manually, at least that's how I understood the answer to this question: When are closed sites removed from SEDE? Journeyman Geek asked about some stuff related to this site, including SEDE, in this answer: The Windows Phone SE site has been archived - but there wasn't any official response to that answer. (The comments there just confirm that this is done manually.)
Should the Windows Phone site be removed from SEDE at some point?
1Although it was pointed out in another Q&A that there are few remaining questions that do not redirect to Area51: Why is there one remaining page on Windows Phone Meta SE?
