Answer 1

From previous question:

"Apparently, that's part of Microsoft Office's Speech and Handwriting Recognition feature. You could try to update your version of Office my going to the Office website, or you could try to disable the S&HR by going to Add/Remove Programs, then Microsoft Office, then click on Change, and then browse to Office Shared Features, Alternative User Input, and select for Speech and Handwriting Recognition (both) "Not available" from the drop-down box"
