Disable double CTRL - ALT -DEL

I use vmware client view 4.5 on workstation "kiosk" with Windows 7 "blocked". I would like to set that the "ctrl - alt - del" press button event is sent only in the virtual machine and not in the local machine. I try to use Group Policy but I don't disable this event in local machine because in that case it shows two screen "one disabled and one not" It is possible?

Thanks

I would think it would have to be disabled on the client side. Inside of the View session users would use ctrl, alt, insert to lock the OS

In fact I would like to disable any screen when I press ctrl alt del on "physic" workstation but I don't know how.

Take a look at this KB. Maybe a GPO can do this too.

I've already looked this article and I use group policy that can only disabled what ctrl alt del show in the screen like task manager, disconnect, change user, etc but my problem is that i wouldn't that the workstation do anything (it's not acceptable a blank screen) when I press button ctrl alt del. I would like to view only the ctrl alt del of the virtual machine.

thanks

This is currently not possible. It requires hooking into Windows at a pretty low level to essentially do what Microsoft doesn't want anyone to do: hook CtrlAltDel so the system doesn't see it first. Workstation has this functionality only because of a component named vmkbd. We currently don't bundle this in the View Client so it is not possible.

Sorry to bump an old thread, but I came across this while looking for a solution and I have infact found a solution to disable Control Alt Delete on a Windows XP machine.  We are using XP ThinClients that have the View Client installed on them.

There is an undocumented way to disable the Ctrl Alt Del key sequence on Windows NT/2000/XP using the registry.
The key, 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : AutoAdminLogon (REG_SZ)' has only two legal values, according to Microsoft: "0" and "1". 0 disables automatic logon of the account stored, and 1 enables it. The strange thing is that if you set the key to "2", it will enable automatic logon AND disable CTRL + ALT + DEL sequence registration by windows on boot, effectively disabling Task Manager, etc... Of course for this to work you will have to set the "DefaultUserName" and "DefaultPassword" keys to the username to automatically logon.
I've found this the easiest way to kill the Ctrl-Alt-Del sequence.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : AutoAdminLogon = "2"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : DefaultUserName = "(the username to automatically logon)"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : DefaultPassword = "(password for default username)"

Sorry, need to bump this.  Just wondering if nzorn's solution above is still needed or if there is some provision in the latest client that handles this?  I'm in the same boat where I am repurposing a test desktop booting the shell directly to the client.  C/A/D still passes on to the physical desktop first.
