Hi,

Thank you for writing to Microsoft Community Forums.

I understand that you’re seeing error messages in Event Viewer. I will certainly try my best to assist you with the issue.

For further clarity on the issue, please respond to the questions below:

Which build version of Windows 10 are you using currently?
Are you aware of any changes made to the PC prior to which you weren’t facing this issue?
Are you facing any issues on the PC?
When exactly do you receive the error?

Refer the article Which version of Windows operating system am I running?

Ideally, if the PC is working fine and you’re not facing any issues then you can safely ignore the error messages.

However, if you’re facing issues on the PC then you can get back to us with the details, and we will assist you further.
