This may be caused by a font setting that is too large. To change the font setting;
- Click on Start > Control Panel > Appearance & Themes > Change Screen Resolution
- Select the "Settings" tab
- Click on "Advanced"
- Change the DPI setting to "Normal size 96 DPI" (before making the change note the setting it is currently at so that you can return it to that setting if you decide to)
- Save those changes
You may have to restart your PC for the change to take effect.
