Your system is recording them, not Microsoft.

However, Microsoft is the one that implemented the keys. They are there on a clean install of Windows since Windows 98 and still exist on Server 2003 with no 3rd party software installations.

Just not sure exactly what the real purpose is for them as I'm unable to find anyting on Microsoft site or Google that explains the real intent or purpose for them.

I'm not saying their evil, I'm not sure what there for.
