虽然平时不怎么关机，但是每次重启系统之后都会看到这个蛋疼的R6025错误也是一件很蛋疼的事情，以前曾经尝试过解决这个问题，虽然当时是没有什么问题了，但是后来这个问题却又出现了（传送门链接：http://www.h4ck.org.cn/2012/11/win7-x64-explorer-exe-r6025-pure-virtual-function-call/）。
今天又看到这个鸟错误，实在受不了鸟，于是直接操起windbg挂在exporer.exe进行调试。启动之后会发现调用堆栈基本没什么东西。
转到未处理的异常，然后中断调试，查看调用堆栈：

可以看到是ntdll返回出现了错误，直接进行分析，得到如下的内容：

系统给出的错误可能原因是ntdll.dll文件，但是用脚指头想想也不可能是这个问题，而加载的用户的dll只有一个，就是：C:\Users\obaby\AppData\Roaming\baidu\BaiduYun\NetdiskExt64.dll – 这个东西是百度云盘的客户端，没有对这个文件进行详细的分析，但是大体已经可以确定问题的原因了，直接删除百度云盘，然后重新启动，嗯，系统从此就清静了。
但是重启之后出现了另外一个问题，就是原来的百度云盘的那个图标没了，在系统的盘符浏览器那里看起来灰常的蛋疼，处理的方式也比较简单，删除注册表的如下项目即可：

原来是百度网盘这坑爹货！问题解决！谢谢！
娃哈哈，还真有遇到同样问题的。可怜的孩子。不过很多的软件做的挺烂得，烂到出了问题都不知道是谁出的。
