Hi, What does powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 command do in Windows? Is it safe to use? Looking for explanation.
 
The command creates and activates the hidden Ultimate Performance power plan in Windows, maximizing CPU performance and disabling power-saving features, ideal for high-performance tasks but increasing power consumption significantly.
 
It basically creates a copy of Windows’ hidden Ultimate Performance power plan using that ID, so you can use it on your system. Totally safe, I’ve used it myself, it just unlocks a high-performance mode with no risk
