How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.

 

System restore points automatically deleted?

Hi Karanza725

Large Windows 10 updates, like those released in march and September each year will automatically delete all your Restore points to maintain system stability

Apart from that, a size is set on your hard drive to store System Restore points, when your restore points exceed that size, older Restore Points are automatically deleted, in order to make room for new restore points

Click your Start Button, then just type restore

From there open the System Restore App

Select your C Drive and click 'Configure'

From there you can set the space used by System Restore points . ..

 

System restore point automatic create not working....need help.

Were you seeing CAPI2 errors with Macrium & System Restore.

And after enabling system protection.
1) Does System Protection automatically create and populate checkpoints to list.
Does System Protection create restore points when called by a program and populate checkpoints to list.

2) I'd like to confirm whether my issue is unique to me or common.
My issue is that I can manually create restore points okay and those manual created will populate to my list.
Automatic restore points do not populate to my list. Albeit, Task Scheduler shows Last Run time change.
Automatic restore points do not populate to my list e.g., with Windows Updates.
When create restore point is called by a program. I see activity that suggest restore point is being created ...but, again the activity does not translate to an entry in my list.
