It is often not possible to directly retrieve an older version of a file in Windows 10. However, there are some tricks you can try.
You may have made a change to a file that you later regret. Or maybe something went wrong and that's why you need an earlier version. In Windows 10, files are usually overwritten when a modified version of them is saved. Therefore, it is usually not possible to consult or restore an older version.

Previous versions

Backups

If you use File History, the built-in backup function of Windows 10, older versions of your files will still be stored Previous versions provided you plug the backup disk into your computer.
Some online backup services add a restore option in the context menu of files so that you can restore them directly from File Explorer.
