An upcoming feature of WordPad has been discovered by enthusiasts, revealing in-app ads that promote Microsoft Office. The change is hidden in recent Insider Preview builds, and not activated for most users.
Wordpad is a very simple text editor, more powerful than Notepad, but still less feature rich than Microsoft Word or LibreOffice Writer. It is good for creating a simple text document without complicated formatting. The good thing about WordPad is that it is a built-in Windows app and you do not need to install it.
