Windows 2K/NT::Security::Cached Credentials
By default, Windows saves the credentials of the last 10 users to logon from a workstation. This allows me, for example, to take my laptop home and logon locally using my domain logon & password allowing me to work with local resources using the same profile that I use at work.
Data Type: REG_SZ
Set to 0 to disable caching credentials.
Set to 1 to just save the last one.
