Thanks again Hazelnut for that ClassicShell link. I went into its settings today and found out how to get back 99% of my old Win7 Start menu the way I had it laid out earlier.
As an extra plus I downloaded 8GadgetPack Tools and got my analog clock back.
The windows' white header solve you posted only lets you turn the headers blue, but only if you use its generic Win10 desktop. No biggie, I will survive. ( I wonder if WindowBlinds is trying to tweak W10s' GUI these days. )

Just looked. They seem pretty peed waiting for a new version that's compatible.
