首先我是参照大神"注册表文件解析完整解决方案”
这篇文章 ,想通过系统hive文件来读写注册表，在xp下读写都没有问题，但在win7 32或64位系统中，发现写入后，利用hive方式也能够读出键值，但是用注册表工具“RegWorkshop.exe”这个查看，键值并不存在。然后用pchunter.exe查看键值，也并不存在，如图1·，但使用pchunter的hive分析模式解析注册表，就能查看到键值，如图2
(图1)
(图2)
写入后，重启电脑，键值就消失了，百思不得解。
这里我贴下我写的代码。希望通过各路大神的帮助能解决问题
驱动部分都是参照上面引用的文章源码里修改文件句柄的访问权限
//

{
dprintf("找到源权限");
Param->AccessMask = Entry->GrantedAccess;
return true;
}
}
else

{
dprintf("修改成功!GrantedAccess:\n");
Entry->GrantedAccess = Param->AccessMask;
return true;
}
}
return false;
