Every time I run SFC ScanNow, Cortana process re-appears. The only way I know how to safely prevent it from working is by trying to rename it to whatever new name, at which point Windows tells me that renaming is not possible and shows me "Try Again" button, then opening Task Manager, select Cortana, and pressing Delete, followed by immediate pressing of "Try Again" button. Then Cortana doesn't come back! The problem is that those renamed Cortana folders still cannot be deleted and I've already got 8 of them, now taking over 1GB of space! How do I get rid of them for good? I am only going to leave one (the latest one) in case some kind of problems related to Cortana arise.
