This is certainly a step backwards. Reminiscent of the web banner days of old. None of these software companies want you to own what you pay for from them. Reducing freedoms and trapping you into these un-optional setups. It's really getting quite frustrating for the consumer. This should be removable and optional to display. It also poses a potential "over the shoulder" security risk for people that work on the go and are in their settings.
Poor move Microsoft. I'd recommend you stop this behavior.
