Wampserver's internal scripts currently use PHP 7.4.33.
It is no longer possible to change this version for the simple reason that I am certain that the scripts work correctly and without error with this version, but there is no guarantee that they will work without error with another PHP version.
A PHP version is less than 100 MB!
