If you use a Windows operating system, you can attempt to restore your files using the ‘System Restore’ utility. Since this tool stores backups of your Windows device, you would be able to recover versions of the file that haven’t been encrypted by the ransomware.
Follow these steps to use the System Restore option:
Navigate to the Control Panel.
Now, select the System and Security option.
Choose Backup and Restore, and click Restore Files from Backup to complete the process.
