I have followed the guide at: support.microsoft.com/kb/2537096 to correct the VSS Warnings detailed in the kb
This initially corrected the issue but after reboot I noticed that the Service (SPWriterV4) was in a disabled state, I set the service back to auto then re-started it and noticed that the original VSS Warnings began to appear again in Event Viewer.
After checking the registry I noticed that the DOMAIN\spfarm entry had been re-created and now continues to do so every time I remove it.
Any guidance here is greatly appreciated as I am currently relying on a batch file to enable and restart the service every 30 minutes.
