thank you for your reply but I think I haven't explained myself very well.
We don't have a problem on the laptop as in we need to use system restore point.
I was showing my daughter how to take a restore point and went to show her where the restore point is should she ever need to use it. When I clicked on the 'system restore' box the next window won't load so it is to get this window to open we need help with please. so it is the window 'restore system files and settings' that won't open.
hope that clearer to understand
