After posting about Hyper-V and Event ID 58 the other week – I had a number of people ask me about Event ID 157. They told me that each time they backed up a virtual machine they were seeing this event inside of the virtual machine as well.
At first, I could not figure out why they were seeing this – as I did not see it on my system. Then I discovered why I was not seeing this – my systems are up-to-date!
So if you are seeing this event log being filed:
- Install these updates!
- Or, know that you can safely ignore this message if it is happening when a virtual machine backup is happening.
