I get this a lot recently when debugging dumps:
Unable to get current machine context, Win32 error 0n30
GetContextState failed, 0x8007001E
It seems mostly when I debug dumps with AMD processors - but today I got it with a system that had an i5
I'm using 10.0.15063.468 WinDbg and kd.exe
When using the new Windows Store version of WinDbg Preview (10.0.16365.1002) I get what I presume to be the correct results

Not much helpful on the web, and ntdebugging blog hasn't posted anything since January of 2016


From this topic: IRQL NOT LESS OR EQUAL with Netgear Wifi adapter - Windows Crashes, BSOD, and Hangs Help and Support
OP identified USB WiFi device as being the problem
Netgear scmndisp.sys dates from 2007 - and I often see this when there are USB WiFi device problems.

kd.exe (10.0.15063.468) finds nt to be at fault (using writhziden's app)
WinDbg Preview (10.0.16365.1002) finds scmndisp.sys to be at fault


Thoughts/ideas/suggestions/discussion?

Does it happen with both Mike's app + Windbg GUI?

Yes it does. The only "solution" that I've found from others is to revert to a previous version haven't tried it myself yet.

EDIT: I'm having problems finding older versions. Any ideas/links?

EDIT2: Currently ripping out all WDK/SDK/Debugging Tools for Windows installations. I didn't realize how much crud I'd accumulated!!!
