My presumption is that there may be an issue with the "Memory: 512GB" part of the My Computer, don't think the Home version of Win10 supports that much.

sorry what does that mean? Im currently using a Windows 10 Pro version.

I am also having issues applying this feature on my ASUS Zenbook 14, I don't know the issue and I tried doing the command prompt and powershell way with nothing happening, what BIOS setting could be interfering with this?

I ran into the same problem on a Microsoft Surface Pro with Windows 10 20H2. After creating Attribes=2 as dword in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00. I could see the settings I enabled unsucessful with powercfg. Please note I created the content of the following .reg file manual with regedit, not through importing a .reg file. BR



Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00]
"Attributes"=dword:00000002

Made an account just to say THANK YOU!

While fixing something else today, I inadvertently got the missing power option to come back. Explained here: Change Maximum Processor Frequency in Windows 10
