my former wrong assumption:
*it drains my notebook battery and I've no shortage of RAM.
In Task manager you see ntoskrnl.exe is eating more CPU time than any other process.
this feature does not appear to be optional and came 2 days ago with the 1st Win10 Update (Win10Pro in my case).*
Modification :
Je veux disable it, au moins to exclude it as a culprit for my (unproven) assumptions.
That process never came to my attention in the last 2 months and in Gestionnaire des tâches's long name it's called "system memory and compressed memory".
Comment désactiver Windows 10 mémoire compression?
Re: Comment désactiver Windows 10 mémoire compression?
This is a [good feature to avoid paging (writing data to pagefile.sys on the HDD)](https://superuser.com/a/952142/174557) .
Si vous voulez to test your Windows 10 without memory compression, [start powershell en tant qu'administrateur](http://www.thewindowsclub.com/how-to-open-an-elevated-powershell-prompt-in-windows-10)
and run the command `Disable-MMAgent -mc` and reboot. This disables the compression. To enable it later again, run again powershell en tant qu'administrateur and run the `Enable-MMAgent -mc` command.
