Search SharePoint ULS Logs with Windows

I have a standard/new Windows 2008 R2 install with SharePoint 2010 and am looking for a SharePoint expectation that occurred sometime during the last week.

So I open windows explorer, then go to the logs directory (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\LOGS). In the toolbar I can enter some search text (exception) or i can Ctrl-F which puts my cursor in the same search box. First it searches the filenames, comes back with no results, and then i click File Contents. And it comes back with still no results.

Now I think, maybe there are no errors, so i search for something that I know is in the log (w3wp), still no results.

In previous versions of windows, i could usually fix this by making *.log files read as text. But apparently (http://technet.microsoft.com/en-us/library/cc725753(WS开发者_如何学JAVA.10).aspx) *.log files should already be read as text.

Any idea how to make the search, really search log files. I would prefer a solution that did not involve installing any 3rd party software (eg like ULSViewer), but registry/powershell settings are okay.

Windows OOTB txt search sucks without installing something like WIndows Search. ULSViewer is not an install, it's .NEt so just copying it to the machine should suffice.
