Hello Claudeir,
I have a Dutch Windows 11 Home 64, that complicates things a little.
I get to: settings> system> power and sleep (Aan/uit & accu). I can not find the "change plan settings" or "change advanced power settings". What looks most like it is change power settings (Energiemodus), but there I can only switch between the three modes, I can not change settings.
When I go into the "old configuration screen"(configuratiescherm), all settings are still the same as they were under Windows 10.
I think the screen/functionality has been removed from Windows 11.
Thanks, Gerard.
