How to make the registry changes take effect immediately?

nothankss

After modifying the registry, how can I make it take effect immediately without restarting? You can end the explorer process manually and then start it again to take effect.
How can I get it in the program? Just like the Group Policy Editor, clicking Apply will take effect immediately.

You should be able to log out.

Yes, how is it used in the program, and what functions are available? Thank you!

First, the registry changes are effective immediately.

What you said is effective, just let the program that reads the value in the registry read it again.
So what you want to achieve is to be able to reload the programs that read the registry.

   // Get the LUID for the shutdown privilege.
 
   LookupPrivilegeValue (NULL, SE_SHUTDOWN_NAME,
        &tkp.Privileges [0] .Luid);
 
   tkp.PrivilegeCount = 1; // one privilege to set
   tkp.Privileges [0] .Attributes = SE_PRIVILEGE_ENABLED;
 
   // Get the shutdown privilege for this process.
 
   AdjustTokenPrivileges (hToken, FALSE,&tkp, 0,
        (PTOKEN_PRIVILEGES) NULL, 0);
 
   if (GetLastError ()! = ERROR_SUCCESS)
      return FALSE;
 
   // Shut down the system and force all applications to close.
 
   if (! ExitWindowsEx (EWX_LOGOFF | EWX_FORCE, 0))
      return FALSE;

It depends on what process your modified registry affects. If it affects desktop operation, directly end the explorer.exe process and create another one without registration. If it is another process, the same, just restart the process!

How do I end the explorer process in the program and then reopen it? How is the application implemented?

I checked online, ::SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, NULL, NULL) can meet the requirements!
