I see that the ATX page on wikipediamentions that 24-pin ATX is backward-compatible, and I can find 20-to-24 pin adapters to buy for a couple of dollars/pounds at lots of places, but I can’t find any mention…

It seems that the recent Synaptics driver update for Synaptics SMBus TouchPad on Windows 10 (build 100049) somehow doesn’t see my middle-button. Uninstalling, and installing an older driver for Windows 8.1 from the HP site (my machine is HP EliteBook 8570w) restores the middle button functionality. Few days later, the driver updates itself again, and…
