How to downgrade IE to support 12306 online booking and other websites

  
 

Small version of the Windows
7 system that has been used for many years, the browser is also IE9, recently, I heard that IE11 is good, 30% faster than similar browsers, reducing CPU usage, so the whim is upgraded. This is good, the online booking 12306 website is not compatible, can not complete the booking task, certainly can not wait for the website upgrade.

Solutions

Given that it is impossible to wait for the website to upgrade, we can only solve our own problems and downgrade IE11. Let me show you first, I am the IE11 version.


Open Control Panel - Programs - Programs and Features - Installed updates and see all the Windows related stuff we installed. Note that this is not seen in the uninstallation of the program, Microsoft is positioning IE for updates, not a software.


Find IE11, right click and select Uninstall.


Uninstalling, please wait a few minutes later, everyone will wait patiently.


The uninstallation is successful and the computer will not take effect.


In the startup interface, Windows Update is automatically configured. Do not shut down during this process.


Completed, I have downgraded IE to IE10, and some IE11 incompatible websites have been opened before.
