system restore has a definite amount of space on a harddrive it uses. when system restore uses up that amount of harddrive space, it starts deleting some of the older restore points to make space for a new one. this means that you wont be able to make a restore point now and then restore your computer to this time a year from now. there may be another program that i don't know of that can do this. so do some research and let us know.
