Advanced users can create custom power plans or modify existing ones using the powercfg command-line tool. For example:

powercfg /query

powercfg /setactive SCHEME_MIN

powercfg /setacvalueindex SCHEME_BALANCED SUB_PROCESSOR PROCTHROTTLEMAX 100

Registry and Service Optimizations

Several registry tweaks and service configurations can improve Windows 10 performance:

1. Disable Visual Effects: System Properties > Advanced > Performance Settings > Adjust for best performance
2. Disable Startup Programs: Task Manager > Startup tab > Disable unnecessary applications
3. Optimize Page File: System Properties > Advanced > Performance Settings > Advanced > Virtual memory
4. Disable Superfetch: Services.msc > Superfetch > Disable (not recommended for HDDs)
