How do I lock and force the user to re-enter one's windows password?

Question

I want to lock the accessing of current operating user, as if the user

clicked on Start → pointed to shutdown → click on LOCK

How to do that in C#?

You can make an application that runs the following command line. No Dll imports involved here. http://www.idsecuritysuite.com/blog/how-to-lock-your-computer-using-command-line — Adrian Marinica, Feb 08 '13 at 14:47
Are you trying authorize the user? Maybe as an admin? http://stackoverflow.com/questions/3583501/c-net-acquire-administrator-rights — MrFox, Feb 08 '13 at 14:49

A much better design that isn't hard coded to your windows system paths, etc:

using System.Runtime.InteropServices;

[DllImport("user32.dll")] public static extern void LockWorkStation();

Then just call LockWorkStation();

 System.Diagnostics.Process.Start("shutdown.exe -l");





      it will LOG OFF your computer and now if the account has secure with some password then windows will ask for password otherwise not.
