Does Microsoft make pieces of software code that don't belong on Microsoft systems?

Not to my knowledge. But the code does not need to be MSFT's.

But the code does not need to be MSFT's.

It was described as a Microsoft implan and I assumed they were wrong about the second term. But if it an non-MS implant targetting MS systems, that would be very serious. But I doubt that's the case.
