Winutilities problem

I downloaded the new winutilities from give away of the day and used disk cleaner and history cleaner, on my vista home premium 64 bit system.

Now microsoft games do not work, when I click a game to play, a window comes up with Microsoft Games, and desktop in it, when I click on desktop, notepad comes up.

When I go to microsoft restore, the only date is a month old.

Any help would be appreciated,
