USB Power Feeds While PC is Shutdown

Just thought I would throw this out there in case it can inspire a driver fix within Windows 10. I recently upgraded from Windows 7 and now my LEDs on my mouse wont shut off once my PC is shutdown (plugged into rear USB port). Additionally, my front USB ports seem to also feed power as I had my phone plugged into the PC and when it shutdown power still fed to it. For clarification I'll list my specs below that may be involved in this issue.

Corsair Carbide Series 500R Chassis
Intel Core i5-3570k Ivy Bridge Processor
Asus P8Z77-V LK LGA Intel Z77 Mobo
Coolmaster MB24 Keyboard/MSK2 Mouse (Note: keyboard LEDs turn off; possibly plugged into a different bus)

Edit: Neither of this issues existed when running Windows 7

I don't know why your mouse stays lit up, but power to USB in an off state is a feature in modern motherboards. There's probably a setting in your bios to disable it if you like.

Oh, ok I'll check that out. Thank you! Just thought it was odd since I had never noticed anything like this before the upgrade.
