1. start-> control panel (click) -> add /remove programs
2. Go to add /remove programs(click).
3. at accessories and utils click details.
4. check if games is unchecked or not. if unchecked , then it has been uninstalled by some super intelligent being.. Check the box next to games.
5. In the same dialog click accessories and then see if calculator is checked or not . if unchecked again super intelligent being is at work.. Check the box next calculator.
6. put your windows xp cd into cd drive.
7. pray that super intelligent being gets some wisdom and stop bothering other humans.
if both of the above are checked and still you don't have ur shortcuts. then remove them from add/ remove windows components and then reinstall it..
