Is it possible to change the Ctrl+Alt+Del Key combination to something else? let's say Alt+Shift+0.

I'm trying to lock a down a system to prevent unauthorized use.

The System is running Windows 7

You can't change it. But can't you just put a password on it?

No Ctrl-Alt-Del is built into the BIOS. You would have to re-write the BIOS code to change it.

Putting a password on the account would require a password when logging on, something that we do not want to happen.

"No password" and "lock down" are contradictional ...

Passwords are not the only way to lock things down.

The system uses a program to scan inserted flash drives for a key file. When the key file is detected it launches our software.

Right click is disabled and the start menu has been removed. The only thing on the desktop is the background.

My Internet isn't working correctly right now... so I'm copying and pasting from a saved article I have of "Article ID: 308226 - Last Review: December 10, 2010 - Revision: 3.1 How to enable or disable the CTRL+ALT+DELETE sequence for logging on to Windows XP, to Windows Vista, and to Windows 7"

Maybe this can do it for you.  

Windows Vista and Windows 7, follow these steps:
Click Start, type Control Userpasswords2, in the Search box and then press ENTER.
Note You are required to type the user name and password when the system prompts the dialog box to type the user name and password of the administrator of the computer.
Click the Advanced tab.
In the Secure logon section, click to clear the Require users to press Ctrl+Alt+Delete check box if you want to disable the CTRL+ALT+DELETE sequence.

Note: On MS-DOS-based computers (and some older UNIX-based systems), pressing CTRL+ALT+DELETE gains the attention of the BIOS, causing a "warm" reboot. You can use the keyboard to shut down the operating system. On Windows-based computers (starting with Microsoft Windows NT), the CTRL+ALT+DELETE sequence is intercepted by Windows. The advantage of the keystroke-intercept technique is to help prevent Windows from being shut down by someone who does not have access to do so.

mchyzik--Perhaps of help

But it is a little unclear what you want to do?  Block access to Task Manager, block logon to PC, etc.?  (There are several other ways to access Task Manager.)

Sorry, I got carried away.  I re-read and realize you want to change the keyboard sequence... not disable it.  So, I don't have an answer and not going for points.  Maybe look at this program, AutoHotKey for shortcuts at http://www.autohotkey.com .  I've never used it and it looks complicated but it might be able to do what you need.  But, check out this link too, because it shows how to change the hotkeys that are built into Windows itself. http://www.autohotkey.com/docs/misc/Override.htm

Let me try and explain a little better of what we are trying to protect.  We have designed special software on our systems which are similar to 'kiosks'.  The software relies on a special 'usb key' for login access.. once 'logged in' the user see's our desktop and can then access our software.  We do not want any acces to other programs on the computer (ie: windows 7 applications, etc).  We have found some users 'tampering' wit hour system to try and break into windows to use it (get onto the internet) at night.. without the 'usb key' (you have to be a paid member to get/use the usb key).  We simply want to inhibit/alter the use the normal ctrl/alt/del sequence so they do not get the task manager as this is where we believe they are gaining access.  We are finding the systems in the morning 'looking for a windows login'... which is caused by them tampering with task manager,  SOOOO... if we could perhaps define a different keystroke for task manager, or something similar so they can not gain access.

Try if changing the following settings in gpedit.msc will help: Locking Ctrl-Alt-Del actionsYou should set all (or at least "Remove Task Manager") to "Enabled", which should prohibt the usage.

Another way would be to rename taskmgr.exe, but because of the protection mechanisms of Vista/W7 that needs some effort (taking ownership, granting access, rename - for all occurances including your localized one).

Since no one seems to understand what I am asking I will try again.

Is there any way to change the Ctrl + Alt + Delete key combination to a different combination?

I would like some other combination such as Alt + Shift + 0 to act exactly as if it were Ctrl + Alt + Delete.

Hopefully this cuts down on all of this confusion.

Again - you can't do that, that's why we try to give you alternatives to your original problem.

Ctrl+Shift+Esc also brings up task manager so you'll need to change that, too?

1. You won't get another ideas, since it is not feasible.
2. The proper way to "ping" a question after over a month is to Request Attention. However, because of above I don't think it will lead to more.

I agree with Qlemo's last comment, but with due respect to Qlemo, accept Speedfox6 post http:#a 34928370 .  Speedfox6 said it cannot be done right at the beginning.

It is a difficult situation to award points for an answer that in no way solves the issue presented. Points have been awarded to the first person who answered with what is now apparent "It cannot be done".
