At work, I have a Windows XP computer. When I use the keyboard shortcut CTRL+ALT+DEL, Task Manager does not open. Instead the login box appears.
Many of you have faced the same problem like this.. Right?? I had found the sollution and I want to share it with you.
The Welcome Screen is the simple login screen that shows your user icon during login. You just click your username and enter your password to login.
When XP is set to use the Welcome screen and you press CTRL+ALT+DEL, Task Manager will open but if the setting is disabled (not checked) and you press CTRL+ALT+DEL, Task Manager does not open. Instead you will see the Windows Classic login prompt (more secure method for logging on). This setting is used mostly by companies where your work PC is joined to a Windows domain.
To change the setting so CTRL+ALT+DEL keyboard shortcut opens Task Manager, click on Start \ Settings \Control Panel, then once Control Panel opens, click on User Accounts icon.
Under Pick a task… section, click the Change the way users log on or off link.
Then click the check box next to Use the Welcome screen, followed by clicking the Apply Options button to enable the setting.
and you are done…!!
NOTE : Note, that your Company may not allow you to change this option and prefer that the secure login screen is used instead.
