How to upgrade PHP on windows?

Hi I need to update my version of PHP. Its running on a windows box. Anyone any experience in doing so?

Security scan shows this


According to its banner, the version of PHP 5.4.x installed on the remote host is a version prior to 5.4.30. It is, therefore, affected by the following vulnerabilities :

- Boundary checking errors exist related to the Fileinfo extension, Composite Document Format (CDF) handling and the functions 'cdf_read_short_sector', 'cdf_check_stream_offset', 'cdf_count_chain', and 'cdf_read_property_info'. (CVE-2014-0207, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487)

- A pascal string size handling error exists related to the Fileinfo extension and the function 'mconvert'.
(CVE-2014-3478)

- A type-confusion error exists related to the Standard PHP Library (SPL) extension and the function 'unserialize'. (CVE-2014-3515)

- An error exists related to configuration scripts and temporary file handling that could allow insecure file usage. (CVE-2014-3981)

- A heap-based buffer overflow error exists related to the function 'dns_get_record' that could allow execution of arbitrary code. (CVE-2014-4049)

- A type-confusion error exists related to the function 'php_print_info' that could allow disclosure of sensitive information. (CVE-2014-4721)

- An error exists related to unserialization and 'SplFileObject' handling that could allow denial of service attacks. (Bug #67072)

- A double free error exists related to the Intl extension and the method 'Locale::parseLocale' having unspecified impact. (Bug #67349)

- A buffer overflow error exists related to the Intl extension and the functions 'locale_get_display_name' and 'uloc_getDisplayName' having unspecified impact.
(Bug #67397)

Note that Nessus has not attempted to exploit these issues, but has instead relied only on the application's self-reported version number.
Solution

This isn't a box I'm 100% familiar with so apologies for the silly question, what would be the easiest way to find these extensions? (assuming any exist)
PHP extensions always exist and they are included with the Windows binaries.  Except for some third party extensions like the Microsoft SQLSRV driver for SQL Server which you download from the Microsoft web site.  They are normally in the 'ext' subdirectory under the PHP subdirectory.  I always put my PHP in C:\PHP but some others don't.
One of the main reasons for 'php.ini' is to tell which extensions to enable.  The ones that are enabled are loaded when PHP is launched and the rest are not.
@gman: normally, the zipfile addresses that by not having a php.ini - it has a couple of samples, but doesn't give either of them the "active" name.

@Dave: I usually copy the existing installation and then install over the top, knowing I can restore it back by just copying the copies back to the original location. that saves having to tell everything that already uses php where to find the new copy.  Another alternative is to use a versioning system (such as tortoisegit) to version the directory - that lets you keep track of updates (not just this one, but any changes to the php ini, new modules etc) and gives you finer control over the content.
What I do is essentially the same except I'm changing only directory names.  I usually copy the 'php.ini' file from the previous version to the new one.  When I'm done the 'new' one has the directory name of the old one and none of my other programs knows the difference.
