Hi To All, Thank you for your responses.
To pwillener your suggested forum solved the problem. By using Ccleaner and then creating a restore point, the system can be restored completely to the new point created, all other points prior to using ccleaner cannot be restored.
To rridgely, using the default settings of ccleaner as from installation, having run ccleaner with these default settings, system restore points are still shown e.g system checkpoint, new software installation, application removed etc, when selecting any restore point windows attempts to restore and upon restart displays a window stating windows cannot be restored to this point.
Having created a manual system restore point after using ccleaner with no problems I can only summise that the problem is due to cleaning the registry of windows, which then causes the problem.
Once again many thanks to you all, keep up the good work on this forum.
Kindest Regards
