Solutions include troubleshooting plug-ins, optimizing settings, and uninstalling suspicious software. 1. Use the ShellExView tool to view and disable non-essential Shell extensions, and gradually test to find plug-ins that slow down the right-click menu; 2. For advanced users, you can lower the menu delay time to 0 or 200 milliseconds by modifying the MenuShowDelay key value in the registry to speed up the response speed, but you need to be careful to backup before operation to avoid causing system abnormalities; 3. Uninstall or update software that may cause conflicts such as old compression tools, screenshot software, antivirus software, etc., and observe whether the right-click menu returns to normal. If the problem is alleviated, it means that it is the performance problem caused by the software.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
