Right-click Start, and then click Explore.
Locate and then click the following folder, where drive is the drive on which Windows is installed: drive:\Program Files\Microsoft Office\Office\Startup
NOTE: This is the default location for the Office Startup folder. If you installed Word to a different location, the path to the Office Startup folder on your computer may be different.
Right-click the third-party dictation add-in file (for example, Dictation.dot), and then click Cut.
Click Start, right-click the My Documents folder, and then click Paste.
Repeat steps 4 and 5 for each third-party dictation add-in file in the Startup folder
