So this morning I noticed that the LEDs were on on the computer I built even after I shut it down. That's how it works by default, but I didn't like it, so changed the setting in the BIOS. I have to think that something reset back to the defaults, and I'm guessing Windows 10? I built it so I know it, but I guess I still don't own it. And don't get me started on how Windows 10 never goes to sleep like it should.

Maybe I'm curmudgeonly, but I'm tired of things I choose being changed on me, things I own be used to profit on me, things I use to spy on me. And its not just software and hardware. For example, I bank at X, but they've merged with another bank and are becoming Y. So now different website, different checks, different name, etc. and for what? for a line on some CEOs resume. Similar when I make a loan and the loan is sold to someone else, and my payment processing routine has to change to accommodate someone else's profit-making deal.

I don't think I've seen Windows touch any BIOS settings with the exception of the boot order (which it only does during install).

It's more likely the CMOS battery is duff or some other issue

Well, if you built it, it was you who put Windows 10 on it. I'm not convinced this is an example of you not owning the hardware so much as not realizing that the software was going to turn on you.

have you tried fixing your i-devices? I would not call it complete control if seemingly unrelated parts stop working after replacing some part yourself

I think GP was being sarcastic.
