Looks like the FSF has weighed in on this exact topic:

https://www.gnu.org/licenses/gpl-faq.html#WindowsRuntimeAndGPL

You can link a GPL program against the MSVC runtime and claim it as a
system library, but you cannot then distribute the MSVC runtime with
your application. The user would have to download the runtime
themselves... which defeats the entire purpose of this exercise.
