This open source program allows you to run any programs with system privileges on almost any verision of Windows, as long as you have admin privileges. I must warn you: running unknown programs with systemprivileges may damage your system.Since you are running Windows 11, you can use this program to run Explorer. Then, double-clicking any program will run it with system privileges. However, because the Windows Start menu is a UWP program, it cannot run with system privileges. You must install a third-party Start menu like StartAllBack or StartIsBack (eppatcher is not usable).
Similarly, no UWP apps can run as system user, including Settings and the Control Center. So this is a bad idea.
