Purchased new Lenovo system, upgraded from Win 8.0 to 8.1. Copied stuff from old system to new, went to defrag the system. There is one drive that shows in Disk Optimization, that does not optimize, no matter how many times I click on it. In the Optimization attachment I am talking about the "\\?\Volume..." drive. I also attached a screen shot of the System disk admin screen. I found some articles online that refer to the upgrade from Win 8.0 to 8.1, but I have not found out how to fix (optimize the drive).
