Windows has advanced power management so the Intel utility is not really needed.

@HedgeFundManager​ If possible, tell me more about this. I found information on the Microsoft website: Power profiles provide system wide configuration of processor power management, impacting all running workloads equally. In contrast, the Quality of Service (QoS) feature provides differentiated performance and power for workloads with different QoS levels. For example, this enables tuning foreground HighQoS activity to prioritize performance, while tuning other QoS levels to prioritize power efficiency. It turns out that these are different things. And I would like to understand whether Dell Power Manager affects all this?

There are advanced settings in the control panel but the defaults are fine for 99.9% of users.

@HedgeFundManager​ I unpacked the driver file as an example. There are many parameters that cannot be viewed (changed) through the control panel. In any case, they are not displayed there. Where in the system (Windows 11) can I view (change) the data entered by this driver?

I would leave well enough alone.

In the UEFI, check to see if C-states are enabled so that the CPU can activate better power management

To many programs to count so I leave well enough alone to be sure windows does not mangled
