注：如下操做对win8 win10 系统都使用
一、经过注册表
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. 设置完成后须要重启系统。函数
写成可导入的REG文件以下：调试
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session Manager/Debug Print Filter]
"DEFAULT"=dword:0000000f
二、使用windbg调试内核
执行以下命令，便可显示DbgPrint输出code
ed nt!Kd_DPFLTR_MASK oxf
三、经过应用程序打开
经过调用 SetDbgPrintFiltering 函数，来修改nt!Kd_DPFLTR_MASK变量ip
ekdprint 就是配置各类DPFLTR_TYPE 为不一样LEVEL 的应用程序。get
**下载ekdprint **cmd
打开DbgPrint输出
在cmd下执行，以下命令it
ekdprint.exe 101 0xf
或者直接双击运行，默认参数就这样。io
关闭DbgPrint输出
ekdprint.exe 101 0
ekdprint使用帮助
c:\test> ekdprint.exe -h ekdprint v1.0 Copyright (C) 2014-2017 ranfs.com usage: ekdprint [ComponentId] [mask] example: ekdprint 101 0x0f Notice: No parameters, default Enable DbgPrint output
返回值：成功执行错误代码0，错误为1。 注：本程序须要管理员权限。class
