How to quickly change the maximum processor state in Windows 10?

+4
−0

I am using a Lenovo Legion laptop and one thing I have noticed is the fan working at full speed from time to time. This seems to be related to the CPU jumping to a high frequency to deliver more processing power.

Since I rarely need all that power, I have changed the power plan to not allow CPU to go beyond 99% (Processor power management -> maximum processor state = 99%).

This prevented the CPU from going to higher frequencies (Power Boost Option?) and the fan almost never goes to a high speed.

Currently, I am making the switch manually and it is quite tedious: power plan -> change advance power settings -> change the maximum processor state.

I would like to make this as simple as possible, ideally using shortcut keys to use my default (99%) and 100% maximum processor state.

Considering how much can be done with either, I wouldn't be the least bit surprised if that setting can be changed through a Powershell script and/or using WMIC. That said, I don't really know where to begin looking for the correct incantation.

Canina‭ Yes, Powershell is the way to go as suggested in this Reddit thread.

However, I think I found a better way (at least in terms of maintainability) and provided it as an answer.
