disable the function key Ctrl＋Alt＋Del

Hello Sum,

Thank you for your question and for reaching out with your question today.

To disable the function key Ctrl+Alt+Del and the "Traditional" option on the virtual keyboard in Windows 11 Pro, you can follow these steps:

Disable Ctrl+Alt+Del:

1. Press the Windows key + R on your keyboard to open the Run dialog box.
2. Type "secpol.msc" (without quotes) and press Enter to open the Local Security Policy.
3. In the Local Security Policy window, navigate to Security Settings -> Local Policies -> Security Options.
4. Locate the policy named "Interactive logon: Do not require CTRL+ALT+DEL" in the list.
5. Double-click on the policy to open its properties.
6. Select the "Enabled" option and click Apply, then click OK.
7. Close the Local Security Policy window.

By enabling this policy, you disable the requirement of pressing Ctrl+Alt+Del to log in or access the secure attention sequence (SAS) options.

Disable the "Traditional" option on the virtual keyboard:

1. Click on the Start button and select the gear icon to open the Windows Settings.
2. In the Settings window, click on "Accessibility" from the list of options.
3. On the left-hand side, click on "Keyboard" under the "Interaction" section.
4. Scroll down and click on the "Advanced keyboard settings" link.
5. In the Advanced keyboard settings, click on the "Input" tab.
6. Under the "Virtual keyboard" section, click on the "On-Screen Keyboard" link.
7. The On-Screen Keyboard will open. Click on the "Options" key on the keyboard.
8. In the options menu, uncheck the "Traditional" option.
9. Close the On-Screen Keyboard.

Disabling the "Traditional" option removes the Ctrl+Alt+Del button from the virtual keyboard, preventing users from using that function.

Please note that these steps are based on the information available up to Windows 11 Pro's release. If Microsoft introduces any changes or updates to the user interface or settings, the steps may vary.
