I have to admit that I immediately thought of the Symantec enterprise software that serves roughly the same purpose, but much more intrusively. That's the sort of thing that seems to kill performance on something with a lot of file opens and closes, like VS, in addition to slowing down app startup. It's popular with businesses.

The oddball feature that causes Windows disk I/O to basically lock up on occasion, and I'm amazed that they haven't turned it off by default by now, is volume shadow copy and the automatic creation of restore points. It's bad on an SSD because it's very slow and uses a lot of space, and on a hard disk it's so slow that it ought to be criminal.
