Kernel trace Windows 7 WinDbg

Question

I'm getting no debug information when debugging en_windows_7_checked_build_dvd_x86_398742. I can't see even my own trace info (ATLTRACE). In opposite, Windows XP Checked works like a charm. I get "Bad QueryIdType:5" msg on debug session start with Windows 7. Kernel debug is set up properly obviously. Please help...

I was able to fix it from within windbg, on windows 7 32 bit:

ed Kd_DEFAULT_Mask 8

According to the msdn article, you can also use the registry, but you must reboot for it to take effect. Create a DWORD key under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Debug Print Filter called DEFAULT with a value of 8.

The up to date microsoft documentation is available here: http://msdn.microsoft.com/en-us/library/windows/hardware/ff551519(v=vs.85).aspx
