Customizing the Windows Security Window
When you press Ctrl+Alt+Delete while logged on to Windows 7, you see the Windows Security window, which contains the following buttons: Lock This Computer, Switch User, Log Off, Change A Password, and Start Task Manager. Of these five commands, all but Switch User are customizable using Windows 7’s group policies.
So if you find that you never use one or more of those commands, or (more likely) if you want to prevent a user from accessing one or more of the commands, you can use group policies to remove them from the Windows Security window.
Here are the steps to follow:
First open Windows Group Policy Editor by opening the ‘search programs and files box’ and then typing gpedit.msc.
When the Group Policy Editor pops up open the User Configuration | Administrative Templates | System | Ctrl+Alt+Del Options branch.
Now double-click one of the following policies:
1. Remove Change Password — You can use this policy to disable the Change A Password button in the Windows Security window.
2. Remove Lock This Computer — You can use this policy to disable the Lock Computer button in the Windows Security window.
3. Remove Task Manager — You can use this policy to disable the Start Task Manager button in the Windows Security window.
4. Remove Logoff — You can use this policy to disable the Log Off button in the Windows Security window.
When you click on one of the above policies a policy dialog box appears. So now click Enabled and then click OK.
Repeat this simple procedure to disable all the buttons you don’t want to display.
