Two warning message:
intl should be installed and enabled for best results

Intl extension is used to improve internationalization support, such as locale aware sorting.

MS Windows

To enable this extension add the following line to your php.ini file usually found in /php:
extension=php_intl.dll
And then set the intl.default_locale and intl.error_level directives in your php.ini file.
[intl]
intl.default_locale = en_utf8
intl.error_level = E_WARNING 

 opcache.enable
PHP setting should be changed.

PHP opcode caching improves performance and lowers memory requirements, OPcache extension is recommended and fully supported.

PHP.ini settings:

[opcache]
opcache.enable = 1
opcache.memory_consumption = 128
opcache.max_accelerated_files = 4000
opcache.revalidate_freq = 60
 
; Required for Moodle
opcache.use_cwd = 1
opcache.validate_timestamps = 1
opcache.save_comments = 1
opcache.enable_file_override = 0

upgrade my php form 5.3 to 5.5
download it from for Windows
http://windows.php.net/download/
download thread-safe
"A Thread Safe version should be used if you install PHP as an Apache module. The Non Thread Safe version should be used if you install PHP as a CGI binary."

The reason is that  when we use Apache http server, we normally use mod-php. The PHP is loaded into Apache as threads. So we need thread safe  PHP  for Apache.

in httpd.conf, line 835 change
LoadModule php5_module "C:\php\php5apache2_2.dll"
to
LoadModule php5_module "C:\php\php5apache2_4.dll"
somehow apache failed. Need to check
