Topic: Adobe.PPKLite signature handler

I understand that if I develop a signature plug-in and I want that every user with Acrobat Reader will be able to verify the signature without the need to install my plug-in, I need to write in the Filter key Adobe.PPKLite, since this handler is built in the Acrobat Reader and able to verify a PDF standard signature.
My question is how Adobe.PPKlite security handler verifies the certificate of the signer which is inserted to the Cert key in the signature dictionary.
Does it look for the root certificate in the Windows system store ?
