A certificate chain processed but terminated in a root certificate which is not trusted by the trust provider

A certificate chain processed but terminated in a root certificate which is not trusted by the trust provider

I noticed that some binaries on my machine were showing up as "Invalid Signature", and looking closer at one of them in particular (Microsoft's "widgets.exe") I noticed something that seemed odd.

Why does it end up with an untrusted root certificate on a Microsoft component?

I dug as far as my limited knowledge in this area can take me, and ended up logging events in Event Viewer for Microsoft/Windows/CAPI2/Operational, and sure enough after a minute or two, the error below appears.

Is this a cause for concern? Why is this only occuring for "widgets.exe"? And if it is a problem, how would I go about resolving this?
