It is quite a good option to donate the old computer to schools and charity organizations, but before you actually do it, one thing you care about the most is the private or important information in the computer, can it be restored and seen by the prying eyes. Here I strongly suggest you have a complete cleanup with Wise Care 365 Pro and erase the disk with Disk Eraser in Privacy Protector column of Wise Care 365, do remember to choose 35 passes. Then all the information deleted and cleaned will not be restored.
