The Win7 UI was comfortable, and still configurable enough that I could make the tool work for me rather than having to work for the tool.

I'd be more interested if it brought back the performance of Win7. That OS was released into a world that still had HDD boot drives and had to pay attention to the details. I still run a Win7 machine that boots in under ten seconds.

Sadly no extension can bring either of those back and we are unlikely to see anything along those lines from MS ever again.
