Windows 8/10 wakes up on its own despite settings?

Question

Windows

Sometimes there is a problem: Windows almost immediately returns from sleep. During the night, the cycle of "woke up - worked - fell asleep" can repeat itself seven times before the computer remains working until the morning.
No, I was not banned in Google, if everything was so simple, this question would not exist. Wake timers are disabled
in power plan settings . Respectively,

C:\Windows>powercfg /waketimers
There are no active wake timers in the system.

C:\Windows>powercfg /devicequery wake_armed
NONE

C:\Windows>powercfg /requests
DISPLAY:
None.

SYSTEM:
None.

AWAYMODE:
None.

EXECUTION:
None.

PERFBOOST:
None.

All relevant UEFI settings are also set to Disabled.
In Device Manager , for all devices, the wake-up checkbox is inactive or unchecked.
Event Log is replete with a dozen events for the last night:

The system has returned from a low power state.

Sleep Time: ‎2015‎-‎06‎-‎08T23:57:16.720464600Z
Wake Time: ‎2015‎-‎06‎-‎08T23:57:59.194424600Z

Wake Source: Unknown

User: LOCAL SERVICE.
The problem manifested itself under both Windows 8.1 and Windows 10 (10130). Please, prompt, where to dig?

Answer 1

No matter how strange it may sound, disabling the hibernation mode, as well as the timers for stopping the disk and when powered from the mains, helps.
cmd commands under admin:
powercfg -h off
powercfg -change -disk-timeout-ac 0
powercfg -change -standby-timeout-ac 0

Answer 2

Since I asked the question, I
- rebooted (after applying the settings, I did not do this);
- turned off wake-timers for all power plans (there are three of them by default) - based on , although the article is a little about something else.
The computer turned itself on only once to update itself.
Alas, I can’t say if any of this helped, and if so, what exactly.
