In the Event Viewer, we find the messages listed below. How can we resolve? Also, we had over 21.5GB's of this until we truncated and shrunk the DB. Is there a reason why this did not purge on its own? How can we set it up to do so?

We are running ML/DNN, so I think it would be best to just upgrade the app_browsers if that is possible. Can you tell me how and where can I find the data to download?

Do I just upload that folder (over-writing the current folder) and the problem is resolved?
