如果是如题所述的Dump文件。
当使用WinDbg Preview调试时，输入命令!threads，提示如下：
0:000> !threads
The version of SOS does not match the version of CLR you are debugging. Please
load the matching version of SOS for the version of CLR you are debugging.
CLR Version: 4.7.3750.0
SOS Version: 4.8.4420.0
Failed to load data access DLL, 0x80004005
Verify that 1) you have a recent build of the debugger (6.2.14 or newer)
2) the file mscordacwks.dll that matches your version of clr.dll is
in the version directory or on the symbol path
3) or, if you are debugging a dump file, verify that the file
mscordacwks___.dll is on your symbol path.
4) you are debugging on supported cross platform architecture as
the dump file. For example, an ARM dump file must be debugged
on an X86 or an ARM machine; an AMD64 dump file must be
debugged on an AMD64 machine.
You can also run the debugger command .cordll to control the debugger's
load of mscordacwks.dll. .cordll -ve -u -l will do a verbose reload.
If that succeeds, the SOS command should work on retry.
If you are debugging a minidump, you need to make sure that your executable
path is pointing to clr.dll as well.
即使去生成dump的机器上Copy了相关版本的dll(sos、clr、mscordacwks)再加载，也是不行，其实吧，就是工具用错了
应该使用对应32位版本的WinDbg(X86)工具调试，但是当我输入命令时提示依然不对：
0:000> !threads
SOS does not support the current target architecture.
这看起来就是SOS不对口呗，后来几经周折，在stackoverflow上找到了一个靠谱儿的答案：
最终，需要加载一个soswow64.dll工具来协助，大家可以看下这个工具的介绍，稍微了解一下：
WOW64将soswow64.dll放到一个文件夹下，比如C:DLLsoswow64.dll
再来打开Windbg调试器：使用命令加载此dll
.load C:DLLsoswow64.dll
0:000> .load C:DLLsoswow64.dll
Successfully hooked IDebugControl::GetExecutingProcessorType.
Failed patching DbgEng!X86MachineInfo::ConvertCanonContextToTarget, stack related commands may not work correctly.
注意以上Failed提示，部分堆栈相关命令可能无法正常工作，但问题不大，先继续！
然后，使用命令!wow64exts.sw切换到x86模式下
0:000> !wow64exts.sw
Switched to Guest (WoW) mode
Ok，万事俱备，接下来就可以正常的玩耍了：
