In Windows, what default event sources are available in the Application Event Log?

I am sure this is frowned upon, as I should distinguish my application using its own event source. But this is for infrequent fatal errors, which should be getting logged elsewhere by my code. I just want a really easy place to find them on a client machine in case it all goes wrong...

When I try to write to the Appliction Event Log, I get a security exception. (The Windows event logging infrastructure is trying to create me a new event source, and gets a security violation.)

I have just answered this here: Using EventLog in ClickOnce application

So I would like to try reusing an existing event source. I have found a only two"generic-sounding" sources in the Application Event Log. Are these always part of a Windows installation, and would make a reasonable choice?

It's really not wise to do this. Existing event sources will be used by either Windows applications, or by third party applications. If any of those are removed, or changed by something like a service pack or patch, your program will crash unless you have implemented exception handling to handle the exception gracefully, but then you wont have any event logging.

Also consider the work you may have to do to port your app to the next version of Windows. I suggest you will be making a rod for your own back.

In the answer I linked to, I suggested the best way to handle the problem, is to install your application using admin privs with the installer creating the source, or by creating a simple app that effectively does the same using the admin role.

The only thing else I can suggest is to always run your application in admin mode.
