Volume Shadow Copy Service, also known as Volume Snapshot Service or VSS, is an inbuilt utility in Windows that allows you to create backup snapshots or copies of computer files/volumes whether you are in use or not. When your files are lost or the system is crashed, you can use it to restore them.

However, when Volume Shadow Copy Service is incapable of completing a backup or restore operation, you will receive Event ID 8193 in Event Viewer. The complete error message is: Event ID: 8193. Volume Shadow Copy Service error: Unexpected error calling routine. Access is denied.

Many factors can contribute to VSS error 8193 Windows 10. Here are some possible culprits:

• Volume Shadow Copy Service is disabled.

• The Network Service account is disabled and System Writer is initialized.

• Other applications that use Volume Shadow Copy Service interfere with the process.

• Some components of Volume Shadow Copy Service are missing or corrupted.

• The disk space is insufficient.

The error code 0x80070006 means "The handle is invalid." This error occurs when the Volume Shadow Copy Service (VSS) tries to access a process that does not exist or that is not running.

The error message "Unexpected error calling routine QueryFullProcessImageNameW" means that VSS was unable to get the name of the process that it was trying to access. This can happen if the process is not running or if the VSS service does not have the permissions to access the process.

If you see this error message, you can try restarting the VSS service. You can also check the permissions for the VSS service to make sure that it has the permissions to access the process.

Here are some possible causes of the error code 0x80070006:

• The process that VSS is trying to access does not exist.

• The process that VSS is trying to access is not running.
