Microsoft wrote:It's important to keep your computer as secure as possible. One way to do so is to enable secure logon so that you are required to press CTRL+ALT+DELETE to log on. Using secure logon provides an additional layer of security for your computer by ensuring that the authentic Windows logon screen appears. When secure logon is enabled, no other program (such as a virus or spyware) can intercept your user name and password as you enter it.
In other words, with Secure Logon enabled, you can be assured that the authentic Windows logon screen appears, making it more difficult for malware to trick you with a fake logon screen.
Enabling or disabling Secure Logon is really quite easy...
Important: You must be logged in using an Administrator account before proceeding with these instructions.
For Windows XP
- Go to Start, then select Run
- Copy the text in the code box below, then paste it in the "Run" window and hit enter
- Code: Select all
Control Userpasswords2
- The User Accounts window will now be open - Select the Advanced tab.
- In the Secure logon section, click the Require users to press Ctrl+Alt+Delete check box
- Close the Secure logon window. The next time you reboot, you will be prompted to press Ctrl+Alt+Delete to log in to your computer.
For Windows Vista and Windows 7
- Click on Start, type netplwiz in the "Search" window, then hit enter
- The User Accounts window will now be open - Select the Advanced tab.
- In the Secure logon section, click the Require users to press Ctrl+Alt+Delete check box
- Close the Secure logon window. The next time you reboot, you will be prompted to press Ctrl+Alt+Delete to log in to your computer.
If you decide you would rather not have Secure Logon enabled, simply repeat the above procedure but this time click the Require users to press Ctrl+Alt+Delete check box again to disable the CTRL+ALT+DELETE sequence.
Note: There is a Microsoft "Fix it for me" download available HERE if you prefer not to do this manually
