In the time of incidents, Windows Event logs provide a plenty of useful information for the Incident responder.As you know Windows can generate thousands of events in few minutes ,in this diary I will talk about some of the most useful events and in the next diary I would discuss how to use PowerShell to search for them .

Here is of the most useful events for Forensics/Incident response:
