Previous versions are copies of files and folders created by
Windows Backup when you back up your files, and copies of files and folders that Windows automatically saves as part of a
restore point. When
system protection is turned on,
Windows 7 will only automatically create previous versions of files and folders that have been modified since the last restore point was made.
When you restore a previous version from a
restore point, the file is already saved on your computer, so you don't have to do anything additional. If you want to restore a previous version of a file or folder from a
backup, after you select the previous version and click Restore, Windows opens the Restore Files wizard, and then you follow the steps in the wizard. The drive or media that your backup is stored on needs to be available for you to restore items from a backup.
This will show you how to use
previous versions to restore files and folders in Windows 7 that you accidentally modified or deleted, or that were damaged. Depending on the type of file or folder, you can open, save to a different location, or restore a previous version.
