Use this script in a TS to set the Default Log File Viewer for *.LOG and *.LO_ files in Windows.
I originally got this script from Jorgen at CCMexec.com who has some great content, but I just shortened it a bit for my own use to use in my Windows Server 2016/2019 Build TS running as a “Run PowerShell Script” step.

I think there is something wrong with line 10
Looks wrong in the ISE and errors with
New-Item : A positional parameter cannot be found that accepts argument ‘C:\Windows\CCM\CMTrace.exe
%1‘.The formatting seemed to get messed up when I pasted it for the post and added some extra characters in that I didn’t notice. I’ve updated it, thanks for letting me know!
Be careful when using this script in tandem with the Group Policy object “set a default associations configuration file” – I found that the OP’s script was working only in one of my OUs, that I was already setting a line as follows: “”
It wasn’t working in my other OUs that used a different xml file as its default associations, but it immediately started working when I added that line from the first xml, to the non-working one.
ah i see the wordpress filtering is stripping out my example – with the brackets removed, what is supposed to be between those two quotations was
Association Identifier=”.log” ProgId=”Log.File” ApplicationName=”Configuration Manager Trace Log Tool”
should be
New-Item -Path HKLM:\SOFTWARE\Classes\.lo_ -Value “Log.File” -Force -ErrorAction SilentlyContinue
New-Item -Path HKLM:\SOFTWARE\Classes\.log -Value “Log.File” -Force -ErrorAction SilentlyContinue
