Late this afternoon Microsoft released Windows 10 Insider Preview build 19546 to Windows Insiders in the Fast Ring. This build comes with just two major new features for testing, a new graphing mode in Windows Calculator, and an Indexer Diagnostics app.

Starting first with the graphing calculator, Microsoft says this has been one of the top feature requests in Feedback Hub. There are a few things you can try out when testing it, which we describe below. These include plotting equations, using equations with variables, and analyzing graphs. Microsoft is also making the project available on GitHub, and is accepting contributions from developers. The app will also be available for anyone running Windows 10 version 1809 or higher.

  • Plot one or more equations on the graph. Enter multiple equations so that you can compare plots against each other and see interactions between the lines. You can also customize the line style and graph viewing window to suit your needs.
  • Add equations with variables. If you enter an equation with a secondary variable (e.g., “y = mx + b”), you’ll be able to easily manipulate those variables so that you can quickly understand how changes to the equation affect the graph.
  • Analyze the graph. Trace plots with your mouse or keyboard to better understand the relationship between variables in the equation on the graph. You can also analyze equations to help identify key graph features, like the x- and y- intercepts.

Secondly, there is the new Indexer Diagnostics app. This app isn’t linked to this build but is rather available in the Microsoft Store as a download. Microsoft says this app was created to help enhance your understanding of the capabilities of search. It is available for anyone running Windows 10 version 1809 or higher. You can find the link below.
