Why doesn't PHP7 find its extensions under Windows 10?

Question

PHP

I can't install PHP extensions on Windows 10
1) edited PHP.INI
- uncommented the necessary extensions
- uncommented the line extension_dir = "ext"
2) copied the copy to C:/WINDOWS
3) set the environment variable PATH -> %Home/PHP ( where the binaries are)
php --ini
Configuration File (php.ini) Path: C:\Windows
Loaded Configuration File: (none)
Scan for additional .ini files in: (none)
Additional .ini files parsed: (none)
When browsing php -m can't find the modules I need.

Answer 1

what for %Home/PHP? %Home%/PHP, probably
then
