The PHP CLI as its called ( php for the Command Line Interface ) is called php.exe It lives in c:\wamp\bin\php\php5.x.y\php.exe ( where x and y are the version numbers of php that you have installed )
If you want to create php scrips to run from the command line then great its easy and very useful.
Create yourself a batch file like this, lets call it phppath.cmd :
PATH=%PATH%;c:\wamp\bin\php\php5.x.y
php -v
Save this into one of your folders that is already on your PATH, so you can run it from anywhere.
Now from a command window, cd into your source folder and run >phppath.
Then run
php bin/magento indexer:reindex
It should work like a dream.
just create your folder path and add "bin" directory For example :
c:\wamp\www\Magento2.0\bin>
and execute below command for reindex all indexes.
php magento indexer:reindex
