Disable-ComputerRestore doesn't turn off system protection

Question

I'm programmatically trying to enable/disable System Restore in Windows 7. I have enable system restore working "Enable-ComputerRestore", but disable is giving me issues.

Disable-ComputerRestore -drive "C:\"

doesn't set my C: drive to "Turn off system protection". It sets it to "Only restore previous versions of files" instead. Anyone have a clue as to why this could be happening?

Answer 1

You just have to do it localy (no remote) as administrator :

The command

Be careful, you have to close the system properties windo and reopen it to see the result.

Answer 2

I'm solving this using WMI and the following C# code adapted from here .

    public void disableSystemRestore(string drive)
    {
        try
        {
            ManagementScope scope = new ManagementScope("\\\\localhost\\root\\default");
            ManagementPath path = new ManagementPath("SystemRestore");
            ObjectGetOptions options = new ObjectGetOptions();
            ManagementClass process = new ManagementClass(scope, path, options);
            ManagementBaseObject inParams = process.GetMethodParameters("Disable");
            inParams["Drive"] =  drive;
            ManagementBaseObject outParams = process.InvokeMethod("Disable", inParams, null);
        }
        catch(ManagementException err)
        {
            MessageBox.Show("An error occurred while trying to execute the WMI method: " + err.Message);
        }
    }
