Windows 10: How do I automate rolling back windows to a restore point?

I work at a place that has a public computer lab. Students make silly changes. We would like to set it up so that the entire lab automatically rolls back to a specific restore point nightly, but I can't figure out how to make this happen. The local community college does this, so I know its possible, but I'm not sure if it is native to windows or if I need a lot of special setup.

System Restore Point Questions

Thanks, Dave!

Suppose I go back to an earlier version of C: with the desired restore point, restore from it and create a restore point on D:, then reload the current C:. Will I be able to restore from that restore point on D:?

Step by step:

1. Enable Restore for D:
   
2. Back up the C: drive with Acronis.
   
3. Restore C: to an earlier date with the desired restore point, from the Acronis backup image.
   
4. Restore the system from the desired restore point.
   
5. See if Restore is still enabled for D:. If not, enable it there, with the same capacity as in step 1.
   
6. Disable Restore for C:.
   
7. Create a restore point. Since there's no availability on C:, it should be created on D:, and be identical to the desired restore point.
   
8. Now put C: back to the current version using the backup created in step 2.
   

Will the system now recognize that restore point on D: and let me restore from it?

(Edited to add the explanation, and step 4.)

 

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.

 

Restore points are using more space than is allocated?

Thank you. 1. 'Disk Space Usage' box clearly states "older restore points will be deleted to make room for new ones" but this is not happening. 2. Step 1 should have deleted all restore points but Step 2 suggests that it had found "older restore points". User settings are being ignored by Windows? Maybe a Windows 10 bug? Not a big problem. Just another annoyance. I'll just have to manually delete RPs from time to time I think.
