对于Windows系统：
1. 打开开始菜单：点击屏幕左下角的“开始”按钮（通常显示为一个蓝色箭头）。
2. 选择“设置”：在开始菜单中搜索“设置”（或直接按下Win键 + I），然后点击进入。
3. 访问“应用和功能”：在设置窗，点击左侧菜单中的“应用”，然后在右侧找到并点击“应用和功能”。
4. 找到默认浏览器：在应用列表中找到“Internet Explorer”，点击它。如果找不到，可能是因为你的系统是最新的，所以默认浏览器已经更改为Edge。
5. 启动浏览器：点击“Internet Explorer”后，系统可能会提示你重启浏览器以完成更新。点击“确定”或“重新启动”按钮。
6. 使用快捷键：如果你想要快速启动浏览器，可以按Win键 + R键，然后输入“inetcpl.cpl”并回车，这将打开Internet选项对话框，在这里你可以调整默认浏览器。
对于Mac系统：
1. 打开应用程序文件夹：在屏幕顶部的菜单栏中，点击“应用程序”图标，然后选择“实用工具”下的“实用工具”。
2. 选择“终端”：在应用程序文件夹中，找到并双击“实用工具”文件夹，然后选择其中的“终端”。
3. 输入命令：在终端中，输入以下命令并按回车键：
