How to remove the power button from Ctrl+Alt+Del screen ? Windows 10
<p>A have this application where i disable the options presented at <strong>Ctrl+Alt+Del</strong> screen by changing the values in windows registry progamatically. (It is imp that i do this due to security reasons).</p>

<p>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..". </p>

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

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

<p>Please respond if any one has any clue.</p>

<p>Thanks in advance.</p>

<p>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.</p>
