Having lots of probs with msconfig as follows:

Currently when I activate PC my system configuration utily screen is appearing which is not normal. Apart from that the system.ini / win.ini sections are showing absolutely nothing.
In the process of trying to analyse what could possibly be wrong I inadvertently unclicked one of the options in Selective Startup which as it turns out has turned off my system restore. T/4 unable to restore to a previous point.
To best of my knowledge whenever any changes are made in msconfig and you restart PC usually a screen appears asking whether to show this message or change the system configuration utiliy when windows start. This message is no longer appearing.
Can anyone offer some advise what is possibly the cause and a maybe a solution to get things back on track.

Thanks
