Windows 10 Servicing Release KB4505903 required for instrumented CPU captures

Steven Pratschner
Program Manager

If you’re running the 1903 build of Windows 10 (the Spring 2019) update, you must have KB4505903 installed to take Function Summary, Callgraph, and Tracked Functions captures.  Without this update, your title will hang when taking one of these captures.

To check whether you have this update, open Settings and go to Update and Recovery->View Update History.

KB4505903 is currently in the process of being rolled out through Windows Update.  If you need the fix before it gets pushed to you, install the patch directly from: http://www.catalog.update.microsoft.com/Search.aspx?q=KB4505903 .

We apologize for any inconvenience.

Steven.
