WordPress Permalinks on Windows IIS

Normally we host the wordpress site in linux hosting and everythings works fine with permalinks. But sometime server may be different , let say for the Windows IIS server the permalinks may not works hence resulting the URL that isnot SEO friendly. So to overcome this issue we need to create web.config in root directory and add the following code in the file.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <rewrite>
      <rules>
        <rule name="wordpress" stopProcessing="true">
          <match url=".*" />
          <conditions logicalGrouping="MatchAll">
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
            <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
          </conditions>
          <action type="Rewrite" url="index.php" />
        </rule>
      </rules>
    </rewrite>
  </system.webServer>
</configuration>
