When I open System Restore it says no restore points have been created (they used to be there, I don't know why they've gone). It says open System Protection but that says there's an unexpected error in the property page.
I tried to run the procedure given in ComputerActive issue 426, entering 'cmd' in the Start box, then in the DOS screen entering 'sfc/scannow' to see if the restore points could be found, but it says 'you must be an Administrator running a console session in order to use the sfc utility'. I'm logged on as Administrator, but I don't know what a console session is nor how to run one. Help appreciated.
I'm running Win 7 Home on a Lenovo all-in-one PC.
