电脑上有很多端口，有些是常用的，有些是不常用的，有些是高危的。高危端口指的是那些容易被黑客利用的端口，比如135、137、138、139和445等。如果你不需要使用这些端口，你可以通过以下方法关闭它们：

使用本地安全策略来设置IP安全策略，禁止所有入站和出站的数据包。使用防火墙来设置高级安全规则，拒绝所有入站和出站的连接请求。使用命令行工具netsh来关闭指定的端口，例如netsh advfirewall firewall add rule name=“Block 445” dir=in action=block protocol=TCP localport=445。

关闭高危端口可以提高电脑的安全性，避免被勒索病毒或者肉鸡等恶意软件攻击。但是也要注意，关闭一些必要的端口可能会影响电脑的正常功能，比如文件共享或者远程桌面等。所以在关闭前，请确保你了解每个端口的作用，并做好备份。
