When I have to look in log files for errors and other things, I always use CMtrace. It is a very good log file viewer. CMtrace is already included in WinPE. But not in windows. So this small .cmd file will add it to windows and then you can use it on all your windows installations.
1. Create a package with “CMTrace.exe” and “copy_cmtrace.cmd”. You can download the here.
2. Create a “Run Command Line” step after WinPE phase in your task sequence with the following settings:
Command line: copy_cmtrace.cmd
After that you can just type “cmtrace” in windows.
