I know that lately a lot of people have had the same problem, i.e. Win 10 won't go to sleep. For me, first it was USOCoreworker (Windows update). So I set that to Manual in Services. Now, it's showing Legacy Kernel when I run powercfg -requests. I'm stumped again. I have win 10 Home Pro 64, 24 gigs ram, ssd main drive, a lot of peripheral USB stuff. I want to put the whole computer system to sleep until I touch the mouse. Power settings accordingly.

Legacy Kernel?

Thanks y'all. You are SO valuable to me, for years!
