Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
You may experience certain situations where you may want to prevent a computer from running a user logon script. For example, you may want to do this when a terminal server hosts a special environment for a forest.
The user logon script is started from the Userinit.exe process. The Userinit registry value describes the programs that are started by the Winlogon.exe process. The Winlogon.exe process retrieves the Userinit startup parameters from a registry entry inside the following Winlogon registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
The parameter that controls the user logon script is set in the UserInitLoginScript variable.
To prevent the system from running the user logon script, the UserInitLoginScript variable must be removed. To do this, follow these steps:
- Click Start, point to Programs, point to Accessories, and then click Notepad.
- Copy and paste the following code into Notepad:
@echo off
Set UserInitLogonScript=
Start %systemroot%\system32\userinit.exe
exit
- Save the text file as a program file by using the .cmd file name extension. For example, save it as DisableLogonScript.cmd.
- Click Start, click Run, type regedit, and then click OK.
- Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
- In the right pane, double-click Userinit.
- In the Value data box, delete the userinit.exe entry, and then type the full path of the file that you created in step 3.
- Click OK.
- Exit Registry Editor.
