Проблемы с теневой копией тома в Windows 7

У меня есть проблема с Теневой копией тома в моем Windows 7 Ultimate PC. В основном я не могу использовать программу, которая полагается на Теневую копию тома, поскольку они всегда перестали работать (включая Windows Backup) с целым списком ошибок (в зависимости от программы). Например, когда я запускаю Windows Backup, я добираюсь:

The backup was not successful. The error is: Windows Backup failed while trying to read from the shadow copy on one of the volumes being backed up. Please check in the event logs for any relevant errors. (0x81000037).

Затем я получаю эту Ошибку VSS:

Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface.  hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process. 

Operation:
   Gathering Writer Data

Context:
   Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220}
   Writer Name: System Writer
   Writer Instance ID: {33e11ab5-bc29-4cd0-b993-656570b23fe3}

Затем, когда я выполняю Образцовое Системное Резервное копирование (версия 9.5), я получаю следующее (после того, как это говорит мне, что существует проблема с VSS):

Volume Shadow Copy Service information: The COM Server with CLSID {4e14fba2-2e22-11d1-9964-00c04fbbb345} and name CEventSystem cannot be started. [0x80070013, The media is write protected.
] 

Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance.  hr = 0x80070013, The media is write protected.
.

] 

Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance.  hr = 0x80070013, The media is write protected.
. 

Затем я получаю высказывание информационного сообщения:

The VSS service is shutting down due to idle timeout. 

(Я получил 5 из тех, когда я пытался выполнить резервное копирование вчера),

Затем я получаю эти предупреждения:

Volume Shadow Copy Service warning: VSS was denied access to the root of volume \\?\Volume{2d3b403a-2f5a-11df-846a-005056c00008}\. Denying administrators from accessing volume roots can cause many unexpected failures, and will prevent VSS from functioning properly.  Check security on the volume, and try the operation again.
