Start Menu problem

[ND22]

I have Vista and it works just fine except one problem: I can't modify start menu privacy options in the taskbar and start menu properties, every time I select those chekboxes and click apply windows deselectes them and as a consequence no word or excel files are remembered by windows to have been modified.

Have you specified any Group or Local Security policy options? These can override your selection.
