Windows 10: OS sleeps after 15 minutes of being idle

I have tried everything. I have changed to never in every area that is offered by my system. I have even changed it in hkey and STILL at various (meaning when it feels the need to change) it either changes or sleeps after 15 minutes. Id done it three times already, this last time all the settings were still set for never and it still slept.
How can I stop my OS from sleeping indefinitely. I dont like the sleep option, never have. Never used it. Dont want to start. Turn on turn off. Im good with that...
If anyone has any other suggestions other than what I have already tried I would greatly appreciate that.

display settings
Power & sleep
{never/never}
clicked additional power settings
Advanced SystemCare Power Plan/change plan settings
{never/never}
save
change advanced power settings
Sleep
Sleep after/never
Allow hybrid sleep/off
Hibernate after/never
Allow wake timers/enable

Power buttons and lids
Display
Never and off

display
Turn off display after/never
Enable adaptive brightness/off
OK
save changes

I found an article that told how to dive into the HKEY and stop it from happening. nothing. still slept.

PC rebooting itself if not used for 15 minutes

Ok, I'm not actually talking to myself here but I have partially solved the issue by switching it to go into sleep mode after 15 minutes, however this is not something I usually have set so I would still like to know why it started rebooting after being
idle since the last windows update.

 

laptop sleep without time limit

My laptop setting was only 15 minutes before sleep but my laptop even not idle, suddenly sleep. What does mean?

 

Hello, suggest you inspect your event log (event viewer) and look for event ID 42 which is recorded when your PC sleeps.
That may help identify what's doing this.

Meanwhile, to hopefully prevent this (as a workaround so you can use your PC), you can download and run 'Don't Sleep' (freeware).

There are many many threads on this forum about sleep issues - please use these as a resource for research.

E.g.
Solved Computer turns off display/goes to sleep when idle for a short time - Windows 10 Forums
Solved Machine goes to sleep, can wake it - Windows 10 Forums
Solved Computer goes into sleep or hibernation whenever idle - Windows 10 Forums
Solved Windows 10 sleeps after 3 minutes, no matter what. - Windows 10 Forums

 

I found an event id 42 but it didn't offer anything that I can see to change. I have changed the hkey before and it still didn't work. I think I will try the don't sleep until this new system that is alive deletes it like it does the download I added to be able to control my files and folders:

I swear this OS is alive... SMH
