Choose the disk protection level that fits how your computer is used and whether or not your users need to save data for a specific length of time.
For example, if your shared computers are used by different people every day, you can set SteadyState to remove all changes at every restart. This is a good choice in a library or an Internet cafÃƒÂ©.
You can also choose to retain changes for a specified period of time. This is a good option if you have the same users every day for a limited duration, such as a school term or an ongoing computer lab project.
However you choose to use Windows Disk Protection, you can rest easy knowing that a clean return to its original state is available.
