Windows Defender can need daily updates to keep up with the threats so there's that and if an update fails it retries. Such retries are logged at Microsoft and I've found they work themselves out over time.
My action is to do nothing when I see this.
My computer is updating every other day. Is this normal? I am thinking someone is putting some type of tracking on it. Is there anyway to stop the updates? I don't see anything about any new updates online.
