I am having the same problem. It's so frustrating! I cannot move, delete, rename. Always get this stupid Invalid MS DOS function.

Thank you Snakeyes, it worked.

Thanks for the reply. Will do.

In the meantime, I took sfc /scannow and it found some errors and fixed them. I guess it's good to go.

Still not resolved, however.

Come back with the results.

It says I've been signed in with a temporary profile and in msconfig it won't go to normal startup.

I have only one account with administrative privileges. However, at reboot, Windows 10 starts fresh. It says preparing system.
