1、安装python （坑，分x86和x64,对应windbg版本）

2、安装pykd：'pip install pykd'

3、安装Windbg插件，

排坑记录：

1、执行!py命令后提示：failed to find python interpreter

解决方案：安装对于版本的python

2、执行!py命令后windbg闪退

排错过程：

windbg加载C:UsersxxxAppDataLocalCrashDumps目录下的dump文件

!analyze -v

应该是环境的问题，搜索中发现：https://stackoverflow.com/questions/43688302/windbg-cant-find-python-interpreter-for-pykd/45856752#45856752

I had this issue when having multiple python installations on the same machine. Managed to solve it by manually creating required registry key, as I did not want to reinstall any python versions, nor change the global path/pythonpath variables.

Note that you will need x64 python for windbgx64 and x86 python for windbgx86

Let's say you want to use python 3.7x86 installed at c:python37_x86, and python 3.6x64installed at c:python36_x64

Create keys leading to HKEY_LOCAL_MACHINESOFTWAREWOW6432NodePythonPythonCore3.7-32InstallPath there, and set the (Default) to c:python37_x86 (the trailing backslash is important!)
Similarly, create keys leading to HKEY_LOCAL_MACHINESOFTWAREPythonPythonCore3.6InstallPath there, and set the (Default) to c:python36_x64
Unfortunately the PYTHONPATH environment variable is still being used, and must match the referenced python version(otherwise you will encounter Fatal Python error: unable to load the file system codec . NOTE: this may only be important if one of the versions is 2.x and the other 3.x. Try making it work without this step

To circumvent the last issue I created .bat files to modify the environment and launch windbg with the correct environment.

For example for launching 32 bit windbg:

set PYTHONPATH=C:python37_x86Lib;[...Rest of the PYTHONPATH for this python version...]
start windbgx -debugArch x86 -c ".load c:dev	oolspykdx86pykd.dll"

解决方案：使用bat脚本启动对应windbg

根据个人环境修改

x86:

e:
cd E:Windows Kits10Debuggersx86
set PYTHONPATH=D:sdkpython37_86Lib;
start windbg

x64

e:
cd E:Windows Kits10Debuggersx64
set PYTHONPATH=D:sdkAnaconda3Lib;
start windbg

over！
