Windows 8 and 8.1 contain built-in spell check features that automatically highlight and correct misspelled words in Internet Explorer 11. There is no add-on to enable -- as in Internet Explorer 10 and 11 on Windows 7 -- to activate spell checking. Access the Typing options to turn the spell check and autocorrect features on and off. The spell check affects not only Internet Explorer, but all applications and programs on the system.
Enabling the Spell Check Features
Mouse over the upper- or lower-right corner of the screen to display the Charms bar and then click "Settings." Click "Change PC settings" -- it may be labeled "PC Settings" or "More PC Settings" -- to display the PC Settings menu. Click "General" in Windows 8. In Windows 8.1, click "PC & devices" and then "Typing." Enable the "Highlight misspelled words" option if you want Internet Explorer 11 to highlight misspelled words without attempting to correct them. To allow the Web browser to also correct misspelled words, enable the "Autocorrect misspelled words" option. The system sometimes corrects words that have been entered as you wished them to be -- such as Internet slang. You can access the correction menu in Internet Explorer 11 by clicking inside a word and pressing "Shift-F10." Restart Internet Explorer to apply the changes; if the spell check features are not working as they were set to do, restart your computer to finalize the change.
