note 105503 added to install.windows.manual

Likely other paths too. Should be checked and documented. ---- Server IP: 69.147.83.197 Probable Submitter: 93.150.0.223 ---- Manual Page -- http://www.php.net/manual/en/install.windows.manual.php Edit -- https://master.php.net/note/edit/105503 Del: integrated -- https://master.php.net/note/delete/105503/integrated Del: useless -- https://master.php.net/note/delete/105503/useless Del: bad code -- https://master.php.net/note/delete/105503/bad+code Del: spam -- https://master.php.net/note/delete/105503/spam Del: non-english -- https://master.php.net/note/delete/105503/non-english Del: in docs -- https://master.php.net/note/delete/105503/in+docs Del: other reasons-- https://master.php.net/note/delete/105503 Reject -- https://master.php.net/note/reject/105503 Search -- https://master.php.net/manage/user-notes.php
