Remove all the
users added by VS Studio. They are there to support remote debugging, and you likely will never use the feature.
In the alternative, use the Sysinternals utility (freeware) called Autlogon:
You can do this yourself through the registry, but it is slightly a pain:
[HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows NT \CurrentVersion \Winlogon]
DefaultUserName = "MyUserName"
DefaultPassword = "MyPassword"
DefaultDomainName = "MyNetworkDomain or MyComputerName"
AutoAdminLogon = "1"
Note the security policy "Don't Display Last Username" must be disabled for the automatic logon to work. This can be done with this STRING registry value:
[HKEY_LOCAL_MACHINE \Software \Microsoft \Windows NT \CurrentVersion \Winlogon]
DontDisplayLastUserName = "0"
