In the process of using Windows, we may have encountered such situations: the system restarts, shuts down or becomes blue screen, black screen without any warning or notice. Then you can no longer log on to the system, or get into an endless loop of blue/black screen + reboot. This case, you may first think that this is probably caused by hardware failures. However, that is almost always caused by conflicts between hardware drivers or errors of system kernel modules. The former is usually shown as a blue screen (+ restart), while the latter is usually shown as an automatic restart by default.

Root refers to the technology that allows user to obtain the Superuser permissions for Android operating system. Root enables user to bypass all kinds of limitations made by the phone's manufacturers, to uninstall the numerous, useless apps that are pre-installed on the phone, and to run some applications that require superuser privileges.

SuperSU (AKA: 超级授权管理) is a professional and very popular Superuser access permissions management edge tool for Android devices that have been rooted. It was originally developed by Chainfire (full name: Jorrit Chainfire Jongma), later purchased by Coding Code Mobile Technology (CCMT) from China in 2015. Although it has stopped development and mysteriously disappeared from the Internet, it has reached the point where it can root Android 5.0/6.0/7.0 perfectly and easily without modifying the Android kernel.

ILSpy is a free and open-source .NET assembly browser and decompression tool that is pretty popular in the C# development field, developed by ICSharpCode (i.e. the development team of SharpDevelop). It has the user interface, layout, and decompilation functions similar to Red Gate Software's .NET Reflector. Moreover, sometimes for some assemblies that can not be decompiled with .NET Reflector (because of encryption), it's still possible to do that using ILSpy. Simply speaking, it has only one purpose - to finally completely replace .NET Reflector and do better.

The runtime library (RTL for short) is literally the library file that a program needs when it's running. It is usually provided in the form of dynamic-link library (DLL for short), and generally includes various functions that are commonly used in programming. It is a practical way to implement the concept of sharing function libraries in Windows. The extensions of these library function files are mainly *.dll, *.ocx (ActiveX control library), and *.drv (old system driver).
