Autocorrect is kind of a love/hate thing no matter what platform you use it on. In Windows 10, it works much the same as on other platforms, automatically replacing misspelled words if they are in the dictionary and applying a red underline if the word isn’t found at all.
The trouble is, Autocorrect’s usefulness in Windows 10 really depends on what kind of device you’re using. Though it sometimes claims to be a system-wide feature, Windows 10’s Autocorrect doesn’t show up everywhere. It works in some universal apps (especially built-in apps like Edge and popular apps like Facebook), but not in others. It’s up to app developers whether they want to use the Windows Spell Checking API or not. Autocorrect doesn’t work on most traditional desktop apps at all. It can even interfere with other spellchecker apps or services you might have installed, such as Spell Check Anywhere or Grammarly.
If you’re using a Windows 10 phone or tablet, you might find Autocorrect handy. On desktop and laptop PCs, probably not so much. It’s enabled by default on all fresh Windows 10 installations, but it’s easy to turn off.
Disable Autocorrect and Other Typing Options
Press Windows+I to open the Settings app.
Click Devices and then in the Devices window, click the Typing category on the left. Turn off the “Autocorrect misspelled words” option to disable Autocorrect. You can also turn off the “Highlight misspelled words” option to disable the squiggly red underlines that appear under misspelled words. If you’re working without a touch screen, those are the only two options you’ll see. If you’re using a touch device, you can also disable additional correction options, such as showing text suggestions while you type and adding a period when you double-space.
If you have any apps open that use Autocorrect, you may have to close and reopen them for the changes to take effect, but that’s really all there is to it.
