On October 28, 2019, I got an e-mail with a link to an answer to a question I had posted. The URL of the link is long and complex, but redirects to:
Within a few days of getting that e-mail, I clicked the link, but there was no answer there. The question has since been "deleted" (actually hidden, although I am still able to access it when logged in), apparently because it got a downvote and has no answer.
The e-mail says that the answer started with: "If you're trying to restore permissions to Windows core OS files/directories, MS has a KB article...". That snippet suggests that the answer told me exactly what I wanted to know, which was documentation on how to revert a changed permission.
Was that answer deleted for some reason? Is it possible for me to see it? If I can't see the whole answer, can I at least be informed of the URL of the KB article it referenced? After all these months, I have not found the information, and I need it.
