DbgView doesn't work in Windows Vista December CTP. When it starts the message box with the following information is shown: "This version of DebugView will not capture kernel debug output for this version of Windows. Check the Sysinternals site for Updates." I use the latest version of programm. I have wrote email to Mark Russinovich ( the author of DebugView ). His answer was: "Sorry, I don't have plans to update DebugView until the official Beta 2 release". So, I don't see any possibility to capture debug kernel output ( except cracking DebugView :) ).

You can capture debug kernel output using Remote Debugger. I have used IEEE 1394 connection on previous versions. To enable kernel debugging through IEEE 1394 on previous versions of Windows Vista ( for example build 5112 ) or Windows XP/2003 you should edit boot.ini and add new line like the following:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Pro" /fastdetect /NoExecute=OptIn /DEBUG /DEBUGPORT=1394 /CHANNEL=4

But.... There is no BOOT.INI in Windows Vista build 5270! MSNning the internet give the me the knowledge how to enable remote debug.

There is a command-line utility BCDEDIT to modify boot manager options.

Steps are:

1. Run cmd.exe
2. Type bcdedit -dbgsettings 1394 channel:4 and press enter ( of course you can choose different channel )
3. Reboot and choose "Debugging mode" in advanced boot menu.

Following steps are equal to steps for previous OS versions.

P.S. Sorry my english is so terrible :(
