Power options missing High Performance option

The command should be: powercfg /list

Well, it looks like this below was reported to work, but it will remove "Sleep" with CsEnabled set to 0.

Leaving the slider at "Best Performance" would be the same as using High Performance though.

 

Fall Creators Update: Missing power mode slider in the taskbar

Hello Mark,

If you have a missing battery slider after the Fall Creators Update, it’s likely because you are using the High Performance power plan. Although it shouldn’t work like that, but it seems that if the high performance plan is enabled, the battery slider disappears.
The fix in this case is simple; select the Balanced power plan and the slider will come back.

We recommend that you post a report regarding the power mode slider in Microsoft Feedback Hub. To post a report, you may follow the steps provided in this

Feel free to post your query should you need assistance.

 

Missing Adjust Screen Brightness slider in Power Options

My HP laptop performed a Windows Update today. As a result, I've lost my "Adjust Screen Brightness" slider in Power Options. I can still find it in Settings - Display.

I have Win 10. I've found a YouTube video (specifically for Win 7) that suggests going to Device Manager - Monitors - Properties - Uninstall Device, but I've also read that doing so will merely result in the same driver being reinstalled.

What should I do to get the "Adjust Screen Brightness" slider back in Power Options?

Thanks so much for your help.
