You should put phpcs.bat and phpcs in your PHP folder - e.g. d:\program\php\phpcs. The CodeSniffer itself should reside in d:\program\php\PEAR\PHP\CodeSniffer - there will be a script autoload.php and a subfolder src.
Then in Settings -> Languages & Frameworks -> PHP -> Code Sniffer you specify the path to phpcs.bat and Validate it.
Then in Settings -> Editor -> Inspections you find the node PHP Code Sniffer validation and enable it. After enabling it you will be able to configure it - specifically choose the coding standard.

This is my phpcs
#!D:\PROGRAM\Inet\Design\php\php.exe

Cannot run program "...\phpcs": CreateProcess error=193, %1 is not a valid Win32-Applicationphp.exeis system-wide discoverable? I mean -- will it show the right path if you runwhere phpin terminal (outside of IDE)?phpcs.bat-- perfect. .BAT file inside calls yourphp.exe(as it does not know anything about PhpStorm and PHP Interpreters and stuff) ... and right now it looks likephp.exeis not actually discoverable by OS. You need to put the path to it into systemPATHvariable. That's what error message suggests me...
