the solution WAS : (its now different if you do a clean install with windows 10 version 20H2)
the "C:\Windows\System32\Tasks\Microsoft\Windows\UpdateOrchestrator\Universal Orchestrator Start" file is now replaced in version 20H2 by UpdateModelTask file
5 nights later after clean install of version 20H2 no awaking in sleep mode, like it did with version 2004 and older version without any modification
read this all before doing anything
with windows 10 home version 2004 :
stop the updater in C:\windows\system32\tasks\microsoft\windows\UpdateOrchestrator by doing these :
DO A COPY of "Universal Orchestrator Start" file to return to "normal" when you'll do the windows updates... store it where you will know to use it for when you'll do windows updates and only modify the the file kept in C:\Windows\System32\Tasks\Microsoft\Windows\UpdateOrchestrator
modify
file "Universal Orchestrator Start" in properties\security, add your user administrator name and check "full control" , disable inheritance in advance
in powershell as administrator,
Disable-ScheduledTask "\Microsoft\Windows\UpdateOrchestrator\Universal Orchestrator Start"
BUT
it stops all updatings
