Windows 10 provides new security features and represents the most secure Windows ever through new techniques and technologies developed to protect users against the latest threats and intrusions.
Having to supply logon information through a password, pin, or even Windows Hello's new biometrics options is a best practice. It helps keep the unwanted from gaining access to your personal information. If you're one of those that just really loved the way Windows used to require the 3-finger salute (Ctrl-Alt-Del) to logon, you can re-enable that in Windows 10 to add an extra level of logon security.
Here's how to do it…
In the "Ask me anything" area of the Windows 10 taskbar…
…type: netplwiz and choose the "Run command" option.
When the "User Accounts" window opens, select the "Advanced" tab and check the box for "Require users to press Ctrl-Alt-Del."
For IT Administrators, this option can be turned on across the entire PC population using Group Policy.
