Fixing error "PHP extension "curl" must be loaded." while installing Magento

While installing Magento I faces a error "PHP extension "curl" must be loaded.". I did some googling and found a solution which mentioned to remove colon(';') before 'extension=php_curl.dll'. To do this open php.ini file on your system and search for "extension=php_curl.dll" and then remove colon. and restart all your sevices. Thats all.
