I want to disable the Shift bypass on a machine with Autologon to make sure the Users can´t lock them out of the machine because the don´t know the Password to get in again.

My current Reg Keys for Autologin in LOCAL MACHINE Winlogon:

• AutoAdminLogon: 1
• DefaultUserName: [UserName]
• DefaultPassword: [Password]
• DefaultDomainName: [myDomain]
• ForceAutologon: 1
