I have some very old system image restore points, and the actual system image in the external hard drive has long been deleted (external HDD partition containing the system images has been formatted).
Yet, if i click on "show more restore points" to reveal the full list, these old (obsolete) restore points show up:



Any idea how to get rid of these in Windows 8.1?

Tried the disk cleanup/more options/restore points.
Disk cleanup just completed, but the problem is NOT fixed.
The "System Image" restore points are not cleaned up by disk cleanup, it just deleted the normal restore points/system checkpoints.
Anything else I can try?
