I run Windows 7.

I notice that there's an environment variable called asl.log. What is this thing? Who puts it there?

What's the purpose of it?

I searched and found only references to MacOS and Apple System Log.
But as I said, this is a Windows7 machine from Dell. It doesn't run MacOS.

Yep, I have it on an XP laptop with iTunes installed too. – Mark Hurd Sep 28 '11 at 17:12

I have it too in W7. A SYSTEM environment variable asl.log with the value Destination=file

Found this reference in the register: HKEY_CURRENT_USER\Software\Apple Inc.\ASL\filenames\asl.log value REG_SZ asl.103843_28May11.log

I am pretty sure it is an Apple thing.
