I had Windows 10 on an older (but not ancient) machine and it was literally unusable. 10-15 minute boot time and another 5 or so just to get a browser to open. The misery didn’t end once things were open; everything was still slower than when I had windows 7 on what would now be considered a truly ancient machine. I put Linux on it and experienced a roughly 5x speedup.
