VSS Event Log Errors: Event IDs 8193 and 13

After upgrading to Windows 10 v1903, two VSS error entries appear in the Application event log during every shutdown. The Event IDs are 8193 and 13 with the event source as VSS. Along with the two error logs, an informational event (ID: 8224) is also recorded during the user session instead of shutdown. Here are the sample events:

VSS Event Log Errors in Windows 10: Event IDs 8193 and 13

It appears that some program or service is trying to start the VSS service during shutdown. Some users say that Acronis True Image or Macrium Reflect cause this. However, the above errors occur in one of my Windows 10 computers where none of the two imaging tools are installed.

The oldest VSS errors (ID: 8193 and 13) date back to May 22, 2019 10:43:47 AM — i.e., within hours after I upgraded to v1903. These errors don’t seem to appear when you shutdown the computer with Fast Startup enabled.

The error code 0x8007045b (return code ERROR_SHUTDOWN_IN_PROGRESS) translates to A system shutdown is in progress. However, it’s unclear what is invoking VSS during the shutdown. I plan to run a boot trace in one of the systems to see if I can find anything. Another thing some users observed is that the automatic Restore Point creation does not work, but creating restore points manually works. Also, turning off the System Restore protection feature stopped the VSS errors from appearing in some systems.

Workaround: Stop the “CryptSvc” service manually before shutdown

I can confirm that the following workaround of stopping Cryptographic Services manually before shutdown prevents the VSS errors from appearing. You can do it by creating a Windows Batch file with the following contents, and run it as administrator.

net stop cryptsvc
shutdown /s /t 0

I shall post more details on this issue if I find anything interesting. Watch this space for further updates.
