Windows 10: Computer run slow after system restore and delete update

Hi, Before this problem occurs, my computer is having an issue so I restore and delete updates.

And when everything seems to turn normal again. I noticed my computer is running slower than usual.

I tried to use the command prompt "sfc /scannow" but no problem detected.

Even a right click on the desktop will show the blue spinning circle first when click. Usually the right-click menu comes up instantly

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.

How to delete inactive System Image Restore Points in System Restore

AndreTen - I have tried Disk Cleanup but unfortunately the problem entries did not go away.
I feel certain Bree (VIP Member) has identified the correct cause of this problem as above and his adviced solution should also do the trick.

Bree - Thank you. I must admit that I did use 'Create system image' a few times in 'Backup & Restore (Windows 7)' instead of 'Backup now' and these ghost entries relate to those actions. You have rightly identified the cause of this issue.
It is crazy that Microsoft has put two different backup options causing the issue of these ghost restore points.

Regarding your advice on how to rectify the issue - I must add that I am not very computer savvy and feel reluctant to use Diskpart utility etc to delete 'WindowsImageBackup\SPPMetadataCache' and 'WindowsImageBackup\Catalog folders' from within 'System Volume Information' folder with command Prompt as I fear damaging the pc by making any mistakes, as I have never done this before.

Please advice if there may be another simpler method to delete the above folders OR if you are able and have time to post a step by step instructions (with pictures if possible) on how to follow your advice. Much appreciated.
