Notepad has been the default text editor of the Windows operating system for along time; the program has not changed all that much in the past decade, and many users install third-party editors like Notepad++, Text Editor Pro, or Sublime Text.
Through Windows 10 Insider Preview Build 17713, Microsoft has also improved Notepad. Business users can now authenticate remote desktop sessions using biometrics with Windows Hello, and a shared PC can be used more quickly thanks to a new "Fast Sign-in" feature. When using the word-wrap feature (which allows long lines to flow onto the next one), you'll now be given an accurate line and column count. Moreover, when users have text selected and open the find dialog, it will automatically populate the search field with the selected text.
For the first time, users can zoom text by holding ctrl and scrolling the mouse wheel. And there are new toolbar options in the PDF Reader in Edge as of Build 17713.
Microsoft said that it's now getting closer to releasing "Redstone 5" (RS5) build of Windows 10. Additionally, there is a new dictionary function that can be used to look up definitions for words when reading a page or document in Reading View or PDFs.
Microsoft's announcement explained that delta updates tended to have larger file sizes (around 300MB to 500MB) than express updates because the delta updates have "the full component (not just the individual files)".
Notepad displays the zoom level in the status bar (if enabled).
Security updates to Windows apps, Windows graphics, Windows datacenter networking, Windows virtualization, and Windows kernel. It seems unlikely that Microsoft will port the features back to previous versions of Windows 10 or even older versions of Windows that the company still supports. You should see fewer authentication errors when using a single gMSA with multiple container instances.
