Found another fix for the error you are getting try this
If the VSS error code 0x800423f3 is reported, the reason is a corrupt state of WMI (wmiutils.dll). This may happen if a registry cleaner was used or a third-party application was uninstalled incorrectly. What you need to do is re-register wmiutils.dll and then restart the WMI service.
In the command prompt, execute the following three lines (note that stopping the WMI service does NOT stop VMs, it only stops the management service):
net stop winmgmt
net start winmgmt
