trace BackgroundTaskHost starts with xperf

Install the Windows Performance Toolkit (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt.aspx) (but use the Windows 10 SDK: https://dev.windows.com/en-us/downloads/windows-10-sdk), open the command prompt with admin rights.

Now run this command to capture the stop/closing of the poceses:

xperf -on PROC_THREAD+LOADER+PROFILE -stackwalk PROFILE+ProcessCreate+ProcessDelete+ImageLoad+ImageUnLoad -buffersize 1024 -MaxFile 1024 -FileMode Circular && timeout 120 && xperf -d C:\BackgroundTaskHost.etl

Let the countdown tick down to zero to stop tracing.

Compress the BackgroundTaskHost.etl as 7z/RAR (to reduce the size), upload it (Onedrive, dropbox) and paste a link here.
