How to Enable or Disable Secure Sign-in with Ctrl+Alt+Delete in Windows 10
It's important to keep your PC as secure as possible. One way to do this is to enable secure sign-in, which requires users to press Ctrl + Alt + Delete on the lock screen before signing in. This guarantees that the authentic Windows sign-in screen appears, protecting the system from programs that mimic a sign-in to retrieve password information.
This tutorial will show you how to enable or disable secure sign-in to require users to press Ctrl + Alt + Delete on the lock screen before signing in to Windows 10.
You must be signed in as an administrator to be able to enable or disable secure sign-in.
If you enable secure sign-in, the default lock screen will show at startup, and the slide show (if turned on) will no longer play for all users.

- Option Two: To Enable or Disable Secure Sign-in in Local Security Policy
- Option Three: To Enable or Disable Secure Sign-in using a REG file
EXAMPLE: Lock screen with Ctrl+Alt+Delete secure sign-in enabled
1 Press the Win + R keys to open Run, type netplwiz into Run, and click/tap on OK.
2 Click/tap on the Advanced tab, and check (on) or uncheck (off) the Require users to press Ctrl+Alt+Delete box under Secure sign-in for what you want set, and click/tap on OK. (see screenshot below)
If the Require users to press Ctrl+Alt+Delete setting is grayed out, then it means that Option Three below is set overriding it.
You can use Option Two below to ungray the Require users to press Ctrl+Alt+Delete setting.
This option is not available in the Windows 10 Home edition since Local Security Policy is not included.
Windows 10 Home PCs can use Option One or Option Three instead.
Using Option Three below to disable will reset this security policy back to Not Defined.
1 Open the Local Security Policy editor.
2 In the left pane, expand Local Policies, and click/tap on Security Options to open it. (see screenshot below)
3 In the right pane of Security Options, double click/tap on Interactive Logon: Do not required CTRL+ALT+DEL to open it's properties. (see screenshot above)
4 Select (dot) Enabled (off) or Disabled (on) for what you want set, and click/tap on OK. (see screenshot below)
5 You can now close Local Security Policy if you like.
The downloadable .reg files below will modify the DWORD value in the registry key below.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
