Description
When a computer starts up (SIMATIC IPC, for example), you are asked which user name you want to use to log on to the system. This interrupts the automatic startup, which is undesirable, for example, after a power failure.

Validity
Microsoft Windows 2000
Microsoft Windows XP
Microsoft Windows Vista
Microsoft Windows 7
Microsoft Windows 8
Microsoft Windows XP Embedded
Microsoft Windows Embedded Standard 2009
Microsoft Windows Embedded Standard 7
Microsoft Windows Server 2003
Microsoft Windows Server 2008
Microsoft Windows Server 2012

Note
Refer to the versions of the Microsoft operating system released for your product in the Compatibility Tool here: Link.

Remedy
As a remedy we recommend you install automatic logon. Depending on whether your computer (SIMATIC IPC, for example) is member of a Windows working group or domain you have different options for installing automatic logon.

Automatic logon to a domain/working group using the Microsoft "Autologon for Windows" tool
To install automatic logon to a domain or working group we recommend you use the Microsoft "Autologon for Windows". The "Autologon for Windows" tool is available at this website:
http://technet.microsoft.com/en-us/sysinternals/bb963905.
The tool can be used with Microsoft Windows XP or Microsoft Windows Server 2003 onwards.

Automatic logon to a domain/working group using the Microsoft "Autologon for Windows" tool
If you wish to install automatic logon without an additional tool on your computer (SIMATIC IPC, for example), proceed as described in the table below.
 
No. Procedure
1

Open the "Run" dialog field with "Start > Run" or the key combination "Windows-Logo + R".

2

If you are using

  • Microsoft Windows 2000

you enter the command

"control userpasswords".

If you are using

  • Microsoft Windows XP

  • Microsoft Windows Vista

  • Microsoft Windows XP Embedded

  • Microsoft Windows Embedded Standard 2009

  • Microsoft Windows Embedded Standard 7

  • Microsoft Windows Server 2003

you enter the command

"control userpasswords2".

If you are using

  • Microsoft Windows 7

  • Microsoft Windows 8

  • Microsoft Windows Server 2008

  • Microsoft Windows Server 2012

you enter the command

"netplwiz.exe".


Fig. 01

Confirm your input by clicking the "OK" button. This opens the "User Accounts" dialog.

3

In the "User Accounts" dialog you open the "Users" tab.

Disable the "Users must enter a user name and password to use this computer" check box.


Fig. 02

Then click the "Apply" button. The "Automatically Log On" dialog window opens.

4

Note
If in a domain you cannot select "Users must enter a user name and password to use this computer", note the following.


Fig. 03

  • Close the "User Accounts" window.

5
  • Repeat steps 1 and 2 displayed in the table, then enter the "regedit.exe" command instead of "netplwiz.exe".


Fig. 04

  • In the "Registry Editor" window you open this Registry folder: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\".

6
  • Right-click the Registry item "AutoAdminLogon" and then click "Modify...".


Fig. 05

7
  • Enter 1 in the "Value data:" field and then click "OK".


Fig. 06

Note
Restart the computer after this modification.

8

Note
If the Registry item "AutoAdminLogon" is not available, proceed as follows.

  • Right-click the Registry folder "Winlogon", then click "New" and then "String Value".


Fig. 07

9
  • Change the "String Value" to "AutoAdminLogon".


Fig. 08

  • Repeat steps 6 and 7 displayed in the table.

10

In the "Automatically Log On" dialog you specify the name and ID that is to be logged on automatically when the computer starts up.

Note
In a domain the following is to be entered as user name: "<Domain name>\user".


Fig. 09

Confirm your input by clicking the "OK" button.

11

Automatic Logon is now installed. After a restart or reboot of the computer (SIMATIC IPC, for example), the Windows logon is executed automatically and you can start using your application immediately.

Notes

  • The two passwords entered in the "Automatically Log On" window are checked for parity. However, the passwords are not checked for correctness. If two identical but incorrect passwords are preset, automatic logon does not work when you start the computer (SIMATIC IPC, for example).

  • You must disable the Enhanced Write Filter (EWF) before making changes in Microsoft Windows Embedded operating systems. See also Entry ID: 40108744.

  • If automatic logon is already configured, but you still want to make changes, then check the option check box "Users must enter a user name and password to use this computer" and then clear it again afterwards. Now you can click the "Accept" or "OK" button and the "Automatically Log On" window opens.

Important
This entry contains information for editing the registry. You should make a backup copy of the Registry before editing it. More information about making a backup copy, restoring and editing the Registry is available in the Microsoft Knowledge Base in Entry ID 256986. Incorrect use of the Registry editor can cause serious problems that affect the complete system and make it necessary to reinstall the operating system. You use the Registry editor at your own risk.
