Magento – how to reindex magento 2 in wamp server windows8

From the XAMPP control panel you click the 'Shell' button. In the console prompt, type cd htdocs/{magento-directory} using the name of your magento directory. Now you can enter the command :

php bin/magento module:enable {module-name}

You can run php pages using php.exe create some php file with php code and in the cmd write:

[PATH to php.ext]\php.exe [path_to_file]\file.php

Example Case for you:

1. My XAMPP is installed on D:\php\ and php.exe resides in D:\php\php and Magento folder is here D:\php\htdocs\MG\m212 ( http://localhost/MG/m212/)
2. Re-indexing:   
    i. Go on to D:
    ii. D:\php\php>php D:\php\htdocs\MG\m212\bin\magento indexer:reindex   

On XAMPP

 Installed Xampp_root/php>php   'Path_to_project'

It will work for you.

EDIT:

1. Go to php installation: cd c:\xampp\php\
2. After that run: php.exe C:\xampp\htdocs\magento2\bin\magento indexer:reindex
