title: How to prevent user changing system date/time (in Windows 7)?
body: <p>Having googled, the general advice is to create a standard, non-administrator account.</p>
  
  <p>I just tried that. I only had one account, my own, which is an administrator and then created a second (not the Guest account). I logged out of my own account and into the new one and tried to change the time. Windows 7 popped up a box asking if my main account would allow this (and prompting for its password).</p>
  
  <p>I have been told "it shall not be possible to change system date/time". I intended to deliver a PC with only a standard account and my s/w, but can't (I think) prevent the user from creating an administrative account and changing date/time.</p>
  
  <p>Can I prevent this programatially from Delphi, or do I just have to say that if the user wants to be destructive I can't prevent it?</p>
