win7安装python3

python官网显示python3.9以上已不支持win7，所以找一下python3.8

Note that Python 3.9+ cannot be used on Windows 7 or earlier.

python3.8提供安装包的版本只到python3.8.10

# https://www.python.org/downloads/release/python-3816/
Python 3.8.10 was the last full bugfix release of Python 3.8 with binary installers.

从这里下载相应安装包：

安装日志显示需要安装KB2533623补丁：

[09D4:09E4][2023-02-23T08:03:25]e000: Detected Windows 7 SP1 without KB2533623
[09D4:09E4][2023-02-23T08:03:25]e000: KB2533623 update is required to continue.

实测该补丁不适用于win7，偶然发现安装火绒后可以安装python3，发现安装了KB4474419补丁，测试确定安装该补丁重启系统后就可以安装pyhton3
