It seems this update, as has prior updates, has messed with Quicken and the way it does online downloads from financial accounts.
What normally happens, if I don't notice the change, is I end up being locked out of the account since it seems the password is handled differently. I will have to go in and reset my online registration to get it back to normal. I have no idea exactly what is changing or whether Quicken or Microsoft is responsible for the problem.
