ultimate list of free system utilities

System utilities always required by the system administrators and network support engineers when you need a utility you have to search from internet and waste some precious time on searching and downloading. I tried to make a list of these utilities and will update it in future so that someone can find it easily and save time. There is a long list and no one can sum it up but one can try. Please share your system utility with us.
