php.ini in green WAMP icon left-click apparently not the same as running one (no replies)

I'm not seeing how to attach a screenshot, but in the Windows 10 system tray WAMP icon, left-clicking into the php.ini option:

I commented out the uncommented line:
error_reporting = E_ALL

and added a new setting (to suppress warnings):
error_reporting = E_ERROR | E_PARSE

However, after restarting the Apache service (and also after restarting all services) the VirtualHost site I'm running still shows PHP warnings.

When I left-click into "PHP settings" (above the "php.ini" left-click option), it shows error_reporting as E_ERROR...

Am I supposed to restart Windows? I'm not sure whether it's using the same file or just not reloading the php.ini file... and I'm not seeing an option to just reload the php.ini file.
