Title: Windows fixes

Rename is not realiable on windows - sometimes it fails in ArchiveDownloader with "Access denied" error.

Also I hit PHP Warnings on Windows when extracting zip files - we already check if everything went fine so we can mute the PHP warnings.

These changes fixed those issues for me.
