Notepad

Notepad is the default text editor of Microsoft Windows.

Since the app's debut appearance in Windows 1.0, it became a part of the Windows Accessories.

Notepad hasn't got major changes for a long time. With Windows 10 October 2018 Update, you can search for text in the Microsoft-own Bing search engine within Notepad. Since Windows 10 May 2020 Update an asterisk (*) in the title bar of a Notepad window shows you whether the changes you made have been saved or not:
 * When an asterisk is shown, the changes have not been saved yet.
 * When it has been gone, the changes have been saved.
