Add Windbg (kd>) Commands to Program Default for Dump Files

jcgriff2 · Jul 5, 2014

Most of us have Windbg set up as the default program for dump files - Register Windbg for dump files (File Associations)

Did you know that you can also add kd commands to run by default as well?

Simply setting up Windbg as the default program leaves Windbg at this point after double-clicking on a dump file -- waiting for you to enter additional commands at the kd> line such as !analyze -v -

Code:

*******************************************************************************
*                                                                             *
*                        Bugcheck Analysis                                    *
*                                                                             *
*******************************************************************************

Use !analyze -v to get detailed debugging information.

BugCheck 50, {fffff80011b0e74d, 8, fffff80011b0e74d, 2}

Could not read faulting driver name
Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+43346 )

I changed my default set up to include these commands -

Code:

!analyze -v;r;kv;lmtn;lmtsmn;.bugcheck

So, when I double-click on a dump file, all of the basic commands that I like to run do so without me having to enter them at the kd> command line.

Try it out!

Back up your registry first (I opted to create a system restore point).

Maneuver to this registry key and add your default Windbg commands -

Code:

HKLM\SOFTWARE\Classes\WinDbg.DumpFile.1\shell\Open\command

The (Default) should look something like this (by default):

Code:

"C:\Program Files (x86)\Windows Kits\8.1\Debuggers\x64\windbg.exe" -z "%1"

I added the kd commands that I mentioned above (listed in RED):

Code:

"C:\Program Files (x86)\Windows Kits\8.1\Debuggers\x64\windbg.exe" -z "%1" -c "!analyze -v;r;kv;lmtn;lmtsmn;.bugcheck"

Double-clicking on a dump file now runs all of the commands in RED by default.

Please note that I made these changes yesterday for the first time, so it is far from 100% tested.

Sorry for the "gravedig", but I just followed these instructions on my work laptop that have WinDbg and it worked perfectly :) Thank you for the tip John, very useful. I'll be sure to do it on my home computer as well.

Glad it worked out.

The registry changes sure do save time from having to enter all of the KD commands manually for every dump -- which can add up quickly each day.

No worries on the "grave dig" -- do so anytime; any thread.

Works perfectly for me :smile9:
Do you have had any problems with the tweak?

Here we are 3.5 years later and while I have received numerous THANK YOU PMs for this -- none have complained that it didn't work.

So... All looks good.

What OS was this used on? I have Windows 10 and in Software/Class.... WinDbg isn't there. Also I always install programs on a different disk.

On my Windows 10 Pro 1703, registry export

Code:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WinDbg.DumpFile.1\shell\Open\command]
@="\"C:\\Program Files (x86)\\Windows Kits\\10\\Debuggers\\x86\\windbg.exe\" -z \"%1\" -c \"!load cmkd; !load procdumpext; !load niemiro; !analyze -v; lmtsmn; !rawstack; !dpx; !sysinfo smbios; !sysinfo machineid; !sysinfo cpuspeed; !thread; .bugcheck; .time;\""
