When I try to install applications they fail with a permissions error when accessing HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows

I have tried regedit, right clicking on permissions. It tells me that I don't have permission to view... but can make changes. In the permissions dialog there are no users or groups i the list. I can add users but when I apply the changes I get access denied.

I have also tried this from UBD4WIN using remote registry editor with the same result.

Any Ideas.

If the value for "MSS: (AutoAdminLogon) Enable Automatic Logon (not recommended)" is not set to "Disabled", this is a finding.

The policy referenced configures the following registry value:

Registry Hive: HKEY_LOCAL_MACHINE Subkey: \Software\Microsoft\Windows NT\CurrentVersion\Winlogon\

Value Name: AutoAdminLogon

Type: REG_SZ Value: 0

Automatic logon for a user is enabled by setting the value of AutoAdminLogon to 1, the value of DefaultUserName to the name of an existing user and DefaultPassword to his/her password.

When in a domain, DefaultDomain is additionally needed.

@set /p password="Enter password for %USERNAME%: " @reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultUserName /t REG_SZ /d %USERNAME% /f @reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /t REG_SZ /d %password% /f @reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d 1 /f

In order to bypass this mechanism, the shift key must be pressed after/while starting Windows.

This article describes an issue where you can't sign in to the system and you're prompted for user name and password repeatedly.

Applies to: Windows Server 2003 Original KB number: 555648

Symptoms

Windows logs on and logs off immediately when you try logging on to Windows. When you type the user name and password, you're again presented with User name and Password dialogue box. You try hard to get in but to no avail.

Cause

You can't log on to system using either Normal Mode or Safe Mode. This occurs only when Winlogon service tries to load the Windows default shell (explorer.exe) and user shell (userinit.exe) from registry. This service searches for Explorer.exe and Userinit.exe in the following path of registry:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

Resolution

Edit these values and type the correct path of shell:

Shell = explorer.exe Userinit=X:\windows\system32\userinit.exe

Note

These files may also be deleted by spywares. You may need to extract them using Windows CD.

Steps for rectifying this problem

• Log on to a networked computer.
• Run Regedit.exe.
• Point your cursor to HKEY_LOCAL_MACHINE.
• Select File > Connect Remote Registry.
• Type the computer name (infected computer).
• Navigate to the following location in registry of destination or infected computer: HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
• Edit these two values in right pane: Shell Userinit
• Change these two values to Shell=explorer.exe Userinit = x:\windows\system32\userinit.exe
• Exit from Registry.
• Restart the infected computer.
• You should be able to log on to the computer.
