Although it was removed from both the installation and the Plugin Manager, you can still add/install the DSpellCheck plugin manually by following the steps below: DSpellCheck was included in the installation process of previous versions of Notepad++, but was recently removed as well.

Official distributors removed many plugins after Notepad++ version 7.5 due to advertisements.
