Windows – How to get back the saved password in the workstation

Older versions of Remote Desktop client store the password in the .rdp file, which can easily be decrypted.

As of Remote Desktop Client v6, credentials are stored using Windows Credentials API. The passwords are securely encrypted using a key tied to your Windows user account (CryptProtectData as described in the SecurityXploded article @StackExchanger linked to), and accessing them requires your Windows password (or the "password recovery" disk). They can be read by any program you run, however, such as NetPass.

Note that if someone has physical access, they can crack the passwords using something like Ophcrack, or install a keylogger.

You will need console access (i.e. be ON the physical server) to reset the password, if you don't have any other passwords available. Is this server connected to an AD server? If so reset the password on the domain controller. If it is only using local usernames and passwords, try something such as the UBCD4Win CD to reset the password.

The way that passwords are stored for users of a Windows system, you can not "recover" or "view" the password in clear text, only hashed form. Because of the vast possibilities that could create that password, you're better off clearing the password, and setting a new one
