VSS fails due to modification by 3rd party software


Backup aborted! - Failed To Create Volume Snapshot. Result Code: 0x8004230f

You may also see the error VSS_E_UNEXPECTED_PROVIDER_ERROR in the VSS log.


This error often occurs if a product called ShadowProtect (from StorageCraft) or other similar programs such as Acronis are or have been installed on your PC.

If you receive the following error at the end of your image log then it is likely that Macrium Reflect has a conflict with other imaging software on your PC (or that has been previously removed).

To fix this problem please take the following steps:

If ShadowProtect is installed on your PC then you must uninstall it if you want to use Macrium Reflect.
  1. Remove the following registry key:
    This key can be left behind after uninstalling ShadowProtect and will cause a VSS error when Reflect creates a shadow copy.
  2. Restart Windows.
For help on editing the registry please see this Microsoft KB article here
If you don't have the registry key above then make sure that you only have the following entry for VSS software providers in registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Providers

If the key shown above is missing it may need to be recreated using the steps below.

To add the default VSS provider registry entry

1. Copy the following text to Windows notepad:
Windows Registry Editor Version 5.00

@="Microsoft Software Shadow Copy provider 1.0"


2. Save as 'VSSWriters.reg'

3. Double click 'VSSWriters.reg' in Windows Explorer to import the entries in your system registry
