Most enterprise companies, frameworks (like Spring Boot 3+), and CI/CD pipelines have standardized on JDK 17, ensuring better compatibility with libraries and tools. 2. Performance Enhancements on Windows
最稳妥的做法是在同一总目录（如 D:\Program Files\Java ）下放置不同版本的JDK文件夹，如：
JDK 17 introduced and refined major language enhancements that make code cleaner and execution faster: jdk17windowsx64binexe better
Enhanced CPU instruction sets that make JVM startup times and garbage collection faster on Windows 10 and 11. 4. Long-Term Support (LTS) Stability
: It adds Java menu items and links to official documentation for easy access. Most enterprise companies, frameworks (like Spring Boot 3+),
The most significant advantage of JDK 17 is its status as an LTS release.
| JDK Version | Release Date | Key Features | | --- | --- | --- | | JDK 8 | March 2014 | Lambda expressions, method references, and functional programming | | JDK 11 | September 2018 | New HTTP client, Flight Recorder, and Java Mission Control | | JDK 17 | September 2021 | Sealed classes, records, pattern matching for switch statements, and improved performance | | JDK Version | Release Date | Key
JDK 17在bin目录下保留了 java 启动器，同时允许我们在启动应用时直接挂载JVM参数来定制垃圾回收器。JDK 17的演进里程碑之一是，它在低延迟场景下表现极其出色，同时通过并发的标记和压缩，可以减少程序长时间的STW（Stop-The-World）停顿。
The installation process for JDK 17 on Windows x64 is straightforward. The jdk-17_windows-x64_bin.exe file provides a simple and intuitive installation experience. Once installed, developers can easily configure the JDK to work with their preferred IDE or text editor.
从生产环境来看，JDK 17现已成为Spring Boot 3和Spring Framework 6等主流框架的最低版本要求，因此对于新项目来说，选择JDK 17不仅可以规避未来的迁移成本，也能直接享受到“开箱即用”的最优化表现。
If a Windows machine has multiple user profiles, software deployment needs to be global.
