C++ Windows Store app validation fails

If  you’ve recently run the Windows App Cert Kit for your C++ Windows Store app, you might have encountered these or similar failures of the Supported API test:

You’ve ensured you’re not building in Debug mode. The error persists. And you could swear, a few days ago, everything was fine.

Clearly, msvc dlls are not the type of code you would have written yourself. So what to do about this?

Luckily, the friendly folks over at the MSDN forums have isolated the issue, verifying that it can (temporarily) be resolved by uninstalling the recent Windows update KB2976978. This is the officially recommended workaround by Microsoft for the time being, as well.

Note that the above errors won’t cause your app to fail submission.

I’ll update this post as soon as there’s anything new!
