If you’re on Windows 10, you already had it. But if you are on Windows 8.1, Windows Server 2012 R2, Windows 7 Service Pack 1 (SP1), or Windows Server 2008 R2 SP1, be aware that during a recent update, Microsoft stuck a little cookie on you.
By the way, it’s a Patch that allows you to send information to Microsoft to improve their operating system.
Unfortunately Microsoft does not reveal enough details on the subject, here is the message from Microsoft on this Patch somewhere.
