Disk Drill for Windows is the best file recovery software in case your Recycle Bin has already been emptied (some moments ago or quite some time) and you don't have any backup files. This app offers versatile algorithms for deleted file recovery to help you with pretty much any data loss issue.
Disconnecting the storage where the data was lost the very moment you realized it happened, greatly increases your chances of deleted file recovery on Windows. It is also recommended that you boot from some other drive rather than the one with erased files. Try not to use the drive with lost data until you are ready to start the file recovery process.
