It's an all or nothing system. You can flush them all by turning off then back one the System Restore feature. You can also control how much space it uses and it does automatically retire old entries as it bumps into the space limit you set. However there is no control to delete this or that date.
1) Is it a good idea to delete old restore dates from System Restore? I have some listed there that are so old I will never use them to restore my computer.
2) If so, how do I do it?
