How to Turn Windows 10 Spell Check and Windows Autocorrect on or Off

We show you how to turn Windows 10 spell check and Windows autocorrect on or off for use in Notepad, WordPad, and other apps.

How to Disable or Turn on Windows 10 Spell Check for Use in WordPad, Notepad, and More

Though many modern applications provide an in-built spell checker, many don't. This even the case with some applications such as WordPad and Notepad, to reduce their footprint. Thankfully, you can turn on the spell check feature, which will provide autocorrect and suggestions for not just Notepad, but your entire system.

Unfortunately, all the kinks haven't been ironed out of the spell checker. Some may find it doesn't work properly in certain applications or that its interface gets in the way. As a result, we'll also be showing you how to turn on spell check in Windows 10, but also how to disable it.

To be clear, spell check shows dotted red lines under misspelled words and shows suggestions for changes. Autocorrect is a bit more aggressive, changing words itself where it thinks there's little chance the user intended to spell them that way.

We're going to be showing two methods to turn Windows autocorrect and spellcheck on or off: via the settings menu, and through the registry. The settings path is the simplest and easiest, but the registry has more chance to persist across updates. Just make sure you read our safe registry editing guide first.
