re: Windows OS is not suitable for large installations because PHP is limited to 32bit even in 64bit Windows, please consider using Linux or other unix-like operating systems instead
I dont think this is a valid statement anymore, php7+ supports 64bit windows. We previously used php5 and had no issues with a medium sized university as well (400 simultaneous active users, moderate hardware, 1000 courses).
