I've had the last two restore points fail completely, so they appear to be a waste of space, and I wouldn't want to restore any earlier than these two points anyway.
That sounds straightforward, but a little research tells me a number of different things.
1: Switching off System Restore completely would automatically clear all relevant System Volume Information, and achieve the result I want.
2: You can get software to carry out this task.
3: You can simply delete the entire folder if the permissions are OK, or sorted out to do this.
4: Don't delete the folder because there's more stuff in there than just System Restore Information. Stuff not recommended you discard.
