Strict Standards: Accessing static property JCache::$_handler as non static in E:\xampp\htdocs\joomla_176\libraries\joomla\cache\cache.php on line 422

2. Change error_reporting = E_ALL | E_STRICT to error_reporting = E_ALL & ~E_NOTICE
3. One more thing select the Server (XAMPP) application and right click-> and check for 'run always as administrator'

After doing the above points, its working fine...
