Ensure that status of all VSS writers and providers are stable:
-
To output the list of writers and their status, enter the following commands in an elevated command prompt:
Important: All writer should have status of [1] Stable.>vssadmin list writers
-
To output the list of providers present, enter the following command in an elevated command prompt:

Ensure that left-over snapshots are cleaned up:
-
Enter the following command in an elevated command prompt:
This will clean up all VSS snapshots.>vssadmin delete shadows /all
Defect operating system may often accumulate hundreds of VSS snapshots that persist in the system and cause Windows to become un-responsive.
In some case, you may not be able to delete the VSS snapshots with the above command. Perform the following instead:
-
To decrease the maximum shadow storage size, enter the following command in an elevated command prompt:
If there is no VSS writer error displayed, but the system is not creating a new VSS snapshot, increase the max shadow storage size on the system instead.>vssadmin resize ShadowStorage /For=C: /On=C: /MaxSize=300MB
-
To increase the maximum shadow storage, enter the following command in an elevated command prompt:
>vssadmin resize ShadowStorage /For=C: /On=C: /MaxSize=10GB
The problem persists after going through all steps outlined above?
Issue related to the Volume Shadow Copy (VSS) Windows services, or the Windows operating system itself should be further pursued with Microsoft support staff.
