How to enable the combo key unlock screen in Win10 System
In the Win10 system lock status, by default, you can press the keyboard or mouse button to enter the logon interface. This may give some people with ulterior motives the opportunity to access the logon page and crack the password. Even if there is no password, they can directly access the system. Therefore, users with high system security requirements can enable Ctrl + Alt + Del to prevent remote unlock. Windows does not recognize the Ctrl + Alt + Del combination key signal sent by the software or application. It can only be implemented by pressing the user's actual button.
The specific method is as follows:
1. Enter regedit in the search bar of Cortana and press enter to enter the Registry Editor.
2. Locate
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon
3. Find DisableCad (if not, create a New DWORD Value and name it), double-click it, change "value data" to 0, and click "OK ",
4. Press Win + R to open "run", enter control userpasswords2, and click "OK ",
5. Click the "advanced" tab in "User Account", select "require users to press Ctrl + Alt + Delete" at the bottom, and click "OK ",
Now, after entering the screen lock page (Press Win + L for testing), a prompt will be displayed, pressing Ctrl + Alt + Del to unlock. No key or mouse button can be unlocked. To restore the default mode, you can change the values modified in the preceding steps to the default project.
