What happenned to my restore points in Windows 10?

They disappeared because there was an automatic update of the operating system.

One creates system restore points to go back in case there is a problem. Typically when you encounter some rpoblem you would want to go back to a restore point you have created. The restore point would still be available to you were it not for the automatic Windows Updates.

It would be nice if there is a way of having OS on one drive that does not update (so restore points are available) and OS on the other that can update and install the better(?) code.
