Sometimes we may want a program to run as a window, to be automatically minimized after running, to run multiple instances of a program with different parameters (i.e.: software multi-opening, multi-boxing), or to automatically appear somewhere with a fixed window size after running... These ideas are beautiful, but they are very difficult to implement. But now you can try Advanced Run.

Windows services are essentially executable applications that can run in the background for a long time. They can be automatically started when the computer starts, and paused and restarted, run in the secure context of a special account or a default account, and do not display any user interface. Therefore, services are ideal for when you need to run a program for long periods of time without affecting other users working on the same computer.

FlightGear Flight Simulator (FlightGear or FGFS for short) is a free, open-source and cross-platform atmospheric and orbital flight simulation tool that was started by David Murr in 1996 and first released in 1997, now developed by FlightGear developers & contributors around the world.

SubInACL is a tiny tool from Microsoft for performing permission management on folders, files, registries, services, and other objects. It was released as one of the tools in Windows Resource Kits. It is very powerful and practical, and much more powerful than cacls and its replacement, icacls. It is considered to be an edge tool for setting access permissions, suitable for professionals such as programmers and administrators.

As we all know, Google Services Framework (GSF for Short) is an important component built into Google's Android system (it's ostensibly an application that can be removed manually, and essentially a package of APIs that are deeply integrated into the Android system and runs in the background). It is mainly used to support the normal launch and running of all Google applications and some 3rd-party apps and games developed based on it.
