For drivers you should blame your OEM instead of pretending that MS completely ignored them when rolling this out.

I don't really know about the missing files, but it's certainly been a common complaint across all new windows releases. Usually the cause has been user error.

I personally find the windows 10 UI to be a significant improvement.
