Windows 7 includes a feature called as the Credential Manager. This is not exactly a new feature and is similar to technology in past versions of Windows like Vista or XP, in the sense that it stores your passwords, which you can access & manage easily. However, in Windows 7 Microsoft has added the ability to back up & restore your passwords.
The default storage vault for the credential manager information is referred to as the Windows Vault.
You can use the Windows 7 Credential Manager to save credentials like user-names & passwords so that you can easily log onto websites or secure computers. You can access the Credential Manager through the Control Panel.

From the Windows 7 Credential Manager, you can :
- Add a Windows credential
- Add a generic credential
- Add a certificate based credential
- Backup and store the Windows Vault
- Restore the Windows vault
All are self explainatory and easy to operate.
