Windows 10: Would a system restore point revert edits made to my system registry?

Hello,

I want to run a program and check if it makes any suspicious edits to my registry for reasons. If I make a restore point before running, and after there are registry edits made to the system, will restoring revert those changes back to normal (as in the original)? Further more, could restoring not restore every part of the system? If so, what parts would be un-revertible?

Thanks.

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.

 

Can a system restore point revert my OS?

I am currently running Windows 10. If I want to use system restore to revert my computer to an earlier point in time, will all recovery options listed keep my computer on Windows 10 or it will one have the ability to revert my system back to Windows
7? And if it reverts me back to Windows 7, will I still be able to get a free upgrade back to Windows 10?

 

System restore points are lost

Hi Tom,

I understand the frustration when Restore points are lost.

Restore points are saved until the disk space System Restore reserves is filled up. As new restore points are created, old ones are deleted. If you turn off system protection (the feature that creates restore points) on a disk, all restore points are deleted
from that disk. When you turn system protection back on, new restore points are created.

Perform steps mentioned below and see if it helps.

a: Press Windows key + X.

b: Then click Command prompt(Admin)

Type Vssadmin list shadowstorage
c: Take note of what the shadow storage allocation is on the drive you're having issues with.

d: Change the allocation by using the Vssadmin command, syntax:
vssadmin resize shadowstorage /On=C: /For=C: /Maxsize=1G (where Maxsize=the amount of disk space you've allocated to System Restore points. In my case it was 20 GB



e: In the case of the C: drive, the syntax would be VSSAdmin resize shadowstorage /On=C: /For=C: /Maxsize =20G, after increasing the size and rebooting my restore points were still intact and no longer being deleted.

Please revert if you have any issues with Windows in future.
