Where can I find the batch file that you used in your demo?

You can create your batch file, here are the content of that batch file
@if %_echo%!==! echo off

set UserOptions=-BufferSize 1024 -MinBuffers 32 -MaxBuffers 32 -Buffering
set KernelOptions=-BufferSize 1024 -MinBuffers 64 -MaxBuffers 64 -Buffering

xperf -start xaml_user -on "Microsoft-Windows-XAML::5"+perftrack %UserOptions%
xperf -on base+cswitch %KernelOptions%

xperf -m BeginTrace
echo Event listeners started, run desired scenario then press any key
pause
xperf -m EndTrace

echo stopping xaml_kernel...
xperf -flush -f xaml_kernel.etl
xperf -stop

echo stopping xaml_user...
xperf -flush xaml_user -f xaml_user.etl
xperf -stop xaml_user

echo merging to xaml_merged.etl...
xperf -merge xaml_user.etl xaml_kernel.etl xaml_merged.etl

This is a great session Kiran, xperf, WPA and DebugSettings are great tools for XAML Windows store app developers.

Does anyone else have problems finding the XAML events discussed in the video? I used the batch file Kiran pasted above, but have no XAML events when I open the logfiles it makes in WPA.

I wrote an step-by-step article based on Kiran's presentation which might help your find the xaml startup events.
