> And the progress on Windows's side is what exactly?

Safety, performance, stability, easier UI (for the average user).

Yeah, none of these things feature well in tv advertisements, but compared to its predecessors Windows 10 actually does excel in all of those. Heck, i installed 10 on my parents' cheapo PC and with the same programs and such installed it actually is more responsive.

> It stills sucks majorly at giving you a proper estimate of the time it will take to copy a file.

That's not a software problem, that's a hardware problem. Particularly on SSDs you have to deal with deletions being surprisingly slow, and in the copying process itself you often have a very fast phase at the beginning when it's just slurping the file into ram; and then it drops off when it runs into the write limit of the target medium and/or runs out of ram to use cache. If you're copying to the same medium you get an even stronger drop due to read/write happening on the same thing.

Predicting this is HARD.

The only way to get reliable predictions out of the copy dialog would be to disable memory caching while copying, and uh, you kinda don't want that. It would just be predictably slow.
