Microsoft simply can not stop updating the notepad. Each Windows 10 update now includes improvements to Notepad, from support for Unix style line endings to Bing searches and performance improvements. Now Microsoft will update the editor much faster.
This change is part of Windows Insider build 1
Dona Sarkar and Brandon LeBlanc from Microsoft explain the change in a blog post:
Notepad has been a popular text editor in Windows for over 30 years. In recent releases, we've made a number of small improvements to Notepad based on your feedback (including support for extended end-of-line, orbital search, and viewing unsaved content). With this build, we'll start a change so that future Notepad updates are automatically available through the store. This gives us the flexibility to respond to problems and feedback beyond the limits of Windows versions. As always, if you have feedback on Notepad, we welcome it in the Feedback Hub under Apps> Notepad.
This is a pretty crazy change: is Notepad really changing so much that Microsoft needs the ability to update it more frequently than every six months? Apparently!
Although initially surprising, it should not be a shock to look at other recent developments. More and more apps have occasionally been moved to the store outside of Windows. The new Windows Terminal application is deployed through the store, and Microsoft's new Chromium-based Edge Web browser is also updated more frequently than the store every six months.
Who knew that Notepad would beat Microsoft Edge in the store?  RELATED: Everything New in Notepad in the October 2018 Update for Windows 10
