Manages power policy and power policy notification delivery. It runs C:\Windows\System32\svchost.exe (svchost.exe -k DcomLaunch -p) as LocalSystem.
Can I disable Power?
Leave it alone. Microsoft's guidance for Windows 10 and 11 IoT Enterprise rates it Don't disable, and its default startup type is Automatic.

How do I change how the PC uses power?
Through power plans, not through the service. Microsoft documents powercfg as the tool that controls power plans, and powercfg /list shows the plans on the PC. The service itself is rated Don't disable, and on Windows 11 build 26300 the running service did not accept a stop request.
Which process hosts the Power service?
