    Unfortunately, as of the Windows 10 ver. 2004 update, all USB ports now remained powered in Standby mode. It’s part of Microsoft’s “Modern Standby” initiative, as they figure some users want to recharge other devices from their PCs’s USB ports. On some systems, network connections also stay on in Standby (!) “so updates and email can be downloaded” when the system isn’t being used. This has greatly reduced Standby time on battery power. I’ve looked far and wide for a fix, but apparently there isn’t one. Even selecting “Stop devices when my screen is off” in Settings > USB settings has no effect; nor does setting to “1” the corresponding registry key (Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\USB\AutomaticSurpriseRemoval), which is why it’s supposed to be there. It’s just the latest example of Microsoft determining how people should use their own computers.
