The best ways to limit the bank's risk are to enable multifactor authentication for each support account and enforce account lockouts after five bad password attempts.

The technician should perform a rollback of the Windows update that caused the issue with the locally attached devices. A rollback is a process of uninstalling an update and restoring the previous version of the system. This can help to fix any compatibility or performance issues caused by the update1. To rollback an update, the technician can use the Settings app, the Control Panel, or the System Restore feature. The technician should also check for any device driver updates that might be needed after rolling back the update.
Disabling the Windows Update service is not a good practice, as it can prevent the system from receiving important security and feature updates. Checking for updates might not fix the issue, as the update that caused the issue might still be installed. Restoring hidden updates is not relevant, as it only applies to updates that have been hidden by the user to prevent them from being installed2.
