I recently read the relevant information about the registry, and I found that I can customize the system default IE search.
When using the IE search, the system default is the 3721 website for searching. In fact, we can change its original definition through the registry to find [HKEY_CURRENT_USER / SOFTWARE / Microsoft / Internet Explorer / Main], find Search Page in the window on the right. After you can see the original http://www.microsoft.com/isapi/redir.dll?prd=ie&ot, you can customize, such as: http://baidu.com
