The Notepad app was first introduced in 1983 as Multi-Tool Notepad, a mouse-based text editor created by Richard Brodie as a stripped-down version of Multi-Tool Word. It has been included in all versions of Windows since Windows 1.0 in 1985.
Notepad in Windows 11 is getting spellcheck and autocorrect features, more than 40 years after the text editor was launched5. The spellcheck feature works similarly to Word or Edge, highlighting misspelled words with a red underline. Autocorrect is also enabled when spellcheck is turned on. Additionally, Notepad now has a redesigned find and replace experience, multi-level undo support, and a dark theme6. These updates aim to improve productivity and performance.
The spellcheck feature in Notepad visually indicates errors by underlining misspelled words with a red squiggly line. When a word is misspelled, the red line appears beneath it, and right-clicking on the word provides suggestions for the correct spelling. This is similar to how spellcheck works in other Microsoft applications like Word or Edge.
