If understand correctly "Toast" is a (recent-ish) windows facility to do the equivalent of daily morning tasks, such as checking for updates (and making the toast, sigh)
.
Do check that (in the git bash) that `git update` checks for updates, and gives you a 'deprecation' warning that you should use the long-form command... This at least checks that some of the update checking is working. Expect it to offer v2.26.2 at this moment. there was a Git security update yesterday.
