trace slow PC/UI with xperf

Install the Windows Performance Toolkit (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt.aspx, use the Win10 v1511 SDK: https://go.microsoft.com/fwlink/p/?LinkID=698771 which is the last version that works in Win7), open the command prompt with admin rights.

Copy this into a new txt file and rename it to CMD and run it from the cmd:
//////////////////////////77

xperf -on latency+FILENAME+FILE_IO+FILE_IO_INIT+DISK_IO_INIT -stackwalk profile+FileCreate+FileCleanup+FileClose+FileRead+FileWrite+FileSetInformation+FileDelete+FileRename+DiskReadInit+DiskWriteInit -buffersize 2048 -MaxFile 2048 -FileMode Circular -f C:\kernel.etl

echo At this point, the test pass should be performed.

pause

Xperf -stop
Xperf -stop USERLogger
Xperf -merge C:\USER.etl C:\kernel.etl C:\Result.etl

del C:\USER.etl
del C:\kernel.etl

    Now capture 1-2 minutes of the slowness.

    zip the Result ETL files as 7z/RAR (to reduce the size), upload it (Onedrive, dropbox, Google Drive) and paste a link here.
