When you Windows computer runs into problems connecting to the Internet, it will display a message with a link called "Troubleshoot". If you click on it, Windows will start to troubleshoot the problem,

In most cases, Windows will identify the problem and repair the problem by itself.

At the same time, Windows will create 3 temporary files named as *.Diagnose.0.etl, *.Repair.1.etl, and *.Verify.2.etl. For example:

131,072   65B963F4-297B-4928-94B3-6D6A0623F8EA.Repair.1.etl
196,608   65B963F4-297B-4928-94B3-6D6A0623F8EA.Diagnose.0.etl

Those temporary files are called ETL (Event Tracing Log) files. If you have the right tool, you open and read them to see what was the root cause of the problem, and how it was repaired.
