A good software developer should add logging of errors, unexpected values, and operations that take longer to complete than expected, and there should be a user option to have these logs sent back to the developer. So ok that seems to be what's happening here. As this is an OS it's probably also sniffing for malware like behaviour.
Being Slashdot I guess the unspoken worry is that MS are recording videos of slashdotters watching porn and the developers are having a good laugh. However I doubt that is happening.
