Can't install it on Windows

[fullstacker999]

1. Ubuntu
   I have tried as ReadMe instructed. In other words, I have made so file and copied into relevant directory that contians other .so files. And I made snappy.ini file in /etc/php/7.2/conf.d and 20-snappy.ini file /etc/php/7.2/mods-available.
   After that, I have tried to composer install again. But still it says my system has no php extension snappy.

2. Windows
   Is there no solution for this extension. I can't find any solution here.
