How to remove the power button from Ctrl+Alt+Del screen ? Windows 10

A have this application where i disable the options presented at Ctrl+Alt+Del screen by changing the values in windows registry progamatically. (It is imp that i do this due to security reasons).

Since i have moved the application to Windows 10, i have been able to remove the command list like "Sign out, Lock, Change a password, Switch user etc..".

Till windows 8 changing the value of, HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoLogoff and HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoClose

from 0 to 1 used to do the trick. However in windows 10, the keys exist but they are not of any help.

Please respond if any one has any clue.

Thanks in advance.

Edit: The application was written in VB6 and it has worked well on CP, Windows 7, 8, 8.1. If there are other ways, like suggested by @code gray, where i could change the group policy options programmatically and obtain the desired result i would appreciate the details for them as well.

Solution

  • I have been able to identify a possible solution.

    For ctrl+Alt+Del screen change the following registry key in Windows 10. If you dont find the "NoClose" key then create one there.

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer "NoClose"=dword:00000001

    For Start menu:

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer "NoClose"=dword:00000001

    This solution will not remove the PowerButton Icon from the Ctrl+Alt+Del but it will be of no use.

    Hope it helps others searching for the same solution. Thanks !
