You can use CCleaner Cloud to remove System Restore points. Once removed, nobody will be able to restore the system to that point.
To remove System Restore points:
- In CCleaner, select the Tools icon at left.
- Click System Restore.
- Using the check boxes on the left, select the restore points you wish to remove.
- Click Remove Selected. You are prompted to confirm the deletion. Click OK.
- If you remove a System Restore point, files and software may still be available from an earlier System Restore point.
- You cannot remove the last System Restore point for safety reasons. As a result, the last System Restore point is always grayed out and cannot be selected.
There are three System Restore points, as follows:
- September 1/2015 Installed Microsoft Office 2007
- September 15/2015 Installed CCleaner
- September 30/2015 Uninstalled Microsoft Office 2007
When you uninstalled Office, Windows deleted the software and related configuration files. If someone restored the system to the September 15, 2009 point, Office 2007 would also be restored.
If you delete the September 15, 2009 point, someone can still restore the system to the September 1, 2009 point to get to Office. The solution is to go back as far as the program was installed (if possible) and to remove that System Restore point.
Note: CCleaner removes references to the System Restore points, but may not actually remove all files related to each point.
