Restore your files with File History
If you're missing an important file or folder that you've backed up, here's how to get it back:
In the search box on the taskbar, type restore files, and then select Restore your files with File History.
Look for the file you need, then use the arrows to see all its versions.
When you find the version you want, select Restore to save it in its original location. To save it in a different place, right-click Restore, select Restore to, and then choose a new location.
Find your backups created on previous versions of Windows
If you used Backup and Restore to back up files or create system image backups in previous versions of Windows, your old backup is still available in Windows 10. In the search box on the taskbar, type control panel. Then select Control Panel > System and Security > Backup and Restore (Windows 7).
