Let's be clear here.
System Restore: A utility from within Windows. When you install software, or when Windows is updated, a System Restore point is created. If there are problems with the install of the software/updates, then you can return Windows to the state it was before the installation/update.
System Recovery: This is usually a destructive re-installation of Windows. Everything is wiped clean and you start again with Windows as if it was new. No data is saved in the process and so we rely on our backups to help us protect the files we cannot afford to lose.
So which did you do, and tell us more please. If you did a system recovery everything is gone. If you have no backups then your only option is to stop using that system immediately and take the disk to a commercial data recovery business who will attempt to recover your lost data. But nothing is guaranteed and the cost is likely to be high.
If you continue using that disk more and more of your file remnants will be over-written.
