cURL only works if apache isnt running as System

[dr_snapid]

Hello friends

When I start apache, the log says:
PHP Warning: PHP Startup: Unable to load dynamic library 'curl' (tried: c:\\xampp\\php7\\ext\\curl (The specified module could not be found.), c:\\xampp\\php7\\ext\\php_curl.dll (The specified module could not be found.)) in Unknown on line 0

If i change the apache windows service to run as my user instead of System, it works fine.

I cannot see any difference in the permissions of php_curl.dll and the other DLLs, system user seems to have full control, same as administrators.

Does anyone have any ideas why curl fails to load when the apache service is running as the local system account?

Hope y'all are awesome

Different environment variables, especially the crucial value of PATH variable.
