View folders first in File Explorer

I often view my files in descending Modified Date order so that the most recent files are at the top.  However, by default the folders appear last when I do this.  The solution is to first sort by Modified Date, and then Shift and click the Name column.

Hosts file location

C:\Windows\System32\drivers\etc

.evt versus .evtx log files

"Classic" .evt log files do not necessarily convert to the new .evtx format.  This becomes an issue when you get sent a log from a Windows Server 2003 server, and need to examine it using the Event Viewer on your Windows 7 pc.  Sometimes you can use Event Viewer's "Save all events as" feature to convert the file to a .evtx file, but this does not always work.  Occasionally you get a "The data is invalid" error.  When this happens, the only way I know of to efficiently examine the log file is to copy it over to a Windows Server 2003 server, and look at it using the old Event Viewer.
