There is a bug in Microsoft Office that will give you a message saying CiceroUIWndFrame not responding when you try and log off or shut down your computer. To fix this error you need to remove the Speech and Handwriting Recognition feature from Microsoft Office. Most people will never use this feature to begin with. To do so, do the following:
Open Control Panel
Double Click on Add/Remove Programs or Programs and Features depending on your version of Windows
Find Microsoft Office and click on the Change button
You may have to check the box that says Choose advanced customization of applications if you did a custom installation of Office
Browse to Office Shared Features, Alternative User Input, and then select for Speech and Handwriting recognition (both) and make them Not Available from the drop-down box and click on Update.
