注：以下操作对win8 win10 系统都使用
1、通过注册表
在HKLM/SYSTEM/CuurentControlSet/Control/Session Manager下新建一个名称为Debug Print Filter的key；在Debug Print Filter下新建一个项：Default,值为0xF.设置完成后需要重启系统。
写成可导入的REG文件如下：
Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session Manager/Debug Print Filter] "DEFAULT"=dword:0000000f2、使用windbg调试内核
执行如下命令，即可显示DbgPrint输出
ed nt!Kd_DPFLTR_MASK oxf3、通过应用程序打开
通过调用 SetDbgPrintFiltering 函数，来修改nt!Kd_DPFLTR_MASK变量
ekdprint 就是配置各种DPFLTR_TYPE 为不同LEVEL 的应用程序。
**下载ekdprint **
打开DbgPrint输出
在cmd下执行，如下命令
ekdprint.exe 101 0xf或者直接双击运行，默认参数就这样。
关闭DbgPrint输出
ekdprint.exe 101 0ekdprint使用帮助
