Updated CA Cert: http://curl.haxx.se/ca/cacert.pem
I know I've done this on another machine but I can't find the resources that I found before when I had to perform this.
I want to update WAMP to use the .pem above, but I can't for the life of me remember where to do that with what command.
If you're running at least php 5.3.7, you can put this in the ini at the end of your php.ini file:
curl.cainfo=c:\path\to\cacert.pem
You'll need to find the specific php.ini file for the version of php one you've selected to use.
