Starting with Microsoft Edge 83.x, Microsoft introduced a new spellcheck experience for Windows users, powered by Windows Spellcheck. The feature is supported on Windows 8.1 and above.

Here's the step-by-step process to enable the Windows SpellChecker on Microsoft Edge which will improve the quality of spell checking.

Microsoft claims in a blog announcement that if you are on Windows 10 May 2020 Update (version 2004), the Chromium-based Microsoft Edge browser consumes 27% less memory by leveraging the Windows segment heap memory.

With this in place, the Win32 applications will now manage memory more efficiently and deliver the best possible browsing experience.
