1. Open the webpage by calling Google browser (Open Baidu)

2. Call IE to open the page (Open Baidu)

3. Call the default browser to open the Baidu page.

All tests are successful. Some computers fail to open IE because they have not installed IE, especially some Ghost systems. I suggest you call Google Chrome, because this is one of the most popular browsers, Google opens the default system if it does not, and IE if it does not.

In the project test, some customers could not open their computers with IE, and finally installed Google.
